 Okay, thank you very much for the presentation. I will present it for finishing this session. Another extraordinary rare items for a mineral that it's mostly fluoride that we are presenting here. Personal ornaments are made of a wide representation of raw materials as we all know, but usually it was less characterized than we deserved. So, our main question was to characterize the transmission and transferring items, and personal ornament items, for evaluating this distribution, its importance and that, and have evaluated this situation for the first time in the green peninsula. We will start presenting the problematic of this color-valued translucent items. Mostly of them, as we will see, are green issues, are green colors, sorry. But we have also different patterns of color that are not usual in late prehistory ornamental items, as pink, pale, purple, et cetera. Ornaments, of course, are very personal categories of transmitting identity in late prehistory societies. And they represent a very special condition of reports between the individual alzine and the group, and transmit the social roles and the social perception of the individual and the reports with the values and the properties of the individual in society. Color and brightness are being highlighted, not some last years, but some of them, that has been a secondary problematic of personal ornaments, have been a minoritarian question of research and traditionally in late prehistory. And we have started in the last decades having more research and characterization of the raw materials, mostly in mineral ornaments. But also, we have still the problematic and the theory problems about considering identity in these matters. I have chosen this picture for this very representative and we have some beautiful pictures and some very beautiful individuals with all the beads and ornaments attached. It's just for reflecting that we usually think about enclave beads when we have these kind of pieces, but they are more complex uses in that, also attached to textiles or to different compliments, to the clothes and arms and belts, et cetera. As we are sitting here in this work of Wright and Garrett, the most complex also, the structure, the communication problem, the more complex also, the color combinations, et cetera. That's also our point with these transverse materials. I also referred here a very classic work of Berlin and Kate, reporting a very non-work of martial science. Evaluating also the complexity of societies, the complexity of color transmission, different aspects of material life. As we can see here, white and black terms or colors, categories also, they discuss also linguistically the perception of that without entering this part. As we can see, people knows the problematic from upper part of the leafy to the early leafy, all the colors are available in personal ornaments and black and white, mostly, until the arrival of amber and green beads and that in the early leafy station, the mid-serena. We can see that that tendons also, the more complex the communication skills, the more complex the social code transmitted, the more complex and the more required codes are needed for that, and colors are reflecting this problematic. We have a problem with the transverse and transparent items, mostly about the literature, usually the items from the last all works and that, we're reporting now there were color beads or necklace beads or ornaments and that, sometimes now concrete this in nothing, about context, about raw materials, nothing. Also, the raw materials were characterized mostly in the case of personal ornaments, just by eye. This is green beads, this is black, this is stone, this is calcite, the most known ones, and we have detected transverse beads are reported always as quarks, it was the only known mineral for the people that excavated that. Sometimes it's true, as we will see, there are quarks beads too, but we don't have nothing more than trusting the world of these people until revisiting the materials. Also, counting on the slide of characterization studies that I have talked in before, we have that also some minerals and some defensals of the components resemble the same when we look at these examples for example, we have white, pink quarks, pink halcyon, pink micas, pink florids. They are all translucent minerals or can be translucent, can be white, green, can be in so many issues and only characterization and precious characterization can solve this problem of identification that we can trust in our naked eye sometimes. We have more examples apart of that farmer that is also very highly persuaded, translucent. Ornament, raw material for ornamentation. As I have said before, the colors that we have also come here are colors that are not present in more raw materials or more contents. Pink, purple are not colors that you're showing in prehistory. Science and dental ethyl, but we have some European samples from upper part of the ethyl in Hong Kong. We have this first approach for fish uses of raw materials made of tracers and minerals and that. Florid was the main mineral that we have documented here in the Green Peninsula. It's a mineral that's relatively frequent in the year, relatively. And it's also very common, relatively also in the western part of the Green Peninsula, practically stops in Germany, but it's also very frequent in France and Belgium and Italy and also in the Green Peninsula. It's also a soft mineral, it's easy to work, it's also easy to cleaveage due to its formation, it's covical formation usually, lots of massive aggregations, et cetera, that it's also very easy as micas or other soft minerals that are used for personal ornamentation. Florids are common as I have said in geological context, but not in archeological context. Or scarce audiences, scarce publications concerning florids are mostly regarding the western part of Europe, but particularly in Belgium works in France. That has been documented since cyberpalliolithic in Belgium, when we have documented also in, what we find in Belgium. There are works that have documented also the florid production of ornaments in some caves with circa 1,400 grand or close to that percentage in some upper-pallific context, and we have seen that in the neolithic, the spread of the transit beads made of florids goes over France, western part of European continent, and are present in so many from Iranian context. The only works that we had in the Green Peninsula as I have presented now, are some sites in all texts of literature, that refers to florids. We have one work from 2002 that performed some PDAs analysis in two bits from the same time that we have studied after that, and one work in 2012 from Joris Cardoso regarding the Extremadura region of Portugal, evaluating the five sites he documented with florid ornaments. Also, florid ornaments were documented in previous digit, yes, as a remark. Due to its easily working properties, transit and appearance. Now, so it's luminescent properties, that is a term of luminescent, the bark of fluorescent, that we think that could be also a performance characteristic of florid ornaments as usually big barrel beads that can afford some light in caves or ritual processes regarding the burials. Our case study in the Green Peninsula, we have one president, very early president with scientific characterization of florid ornaments from Casa da Moura in Ovidos, Portugal, in 19th century, this very old case. The cases I have cited before, this is the only literature that exists for the Green Peninsula, and the first regional approach, a part of sitting in florids, sometimes wrongly, was this work of Cardoso. We have identified 35 sites here in Green Peninsula regarding Spain and Portugal with this set of materials. It's also the transverse beads, and we have characterized it 72 items, that we reported 72 items. We have analyzed it 46, as we have used it in different stages of our research projects with ramensentroscope, aspectroscope, X-ray refraction, portable energy, dispersive, X-rays, et cetera, et cetera. This is the fortunately also for this mineral that with industrial interest, so for our sociologists, it's very hard to define geological outcrops and define the provenance of these geological sources. And we have this beautiful map from the Geological European Institute with the main outcrops of the Green Peninsula in the western part of the Pure with florids. As we can see, the main of the fountains of florid ornaments, here only reported florid ornaments are very close to the geological outcrops, exception made for the Tagus basin, as we will discuss in the last part. Every region has more or less close access or regional access to circuits that provided these minerals. This is the inventory of the items. It's a very scarce quantity, proportionally to other minerals used for historic ornamentation. And the total weight we have for florid ornaments are only 264 grams. That's a very low-represented quantity. There are some identifications also when we characterize the florids. We have to identify three components, maybe rare bands for florids. And we are trying now to solve the question of provenance. We are trying to identify this characteristic of florids. These three components are representative probably provenance studies. More spectra, one of these groups is characterized for this band here, this spiking and 320 more or less. Band in the Raman. These are the characteristics of the first group we have identified. With these bands, also another group that is more scarce in representation. And the last one is only relative to florid beds from darker colors or mostly part of them. Maybe correspond to these rare elements that provided also color characteristic. We have the very special case in here in Antigrande de la Comenda de Igreza in Ibera region that it's the megalith. It's a very important orthostatic megalith from the last 40 million in the middle of Calculated, the middle of the million. This is the represented border context that has already more transminerals, three, four beds, one of them decorated as you can see here with this particular pattern. And this bead that is the second larger in the Iberian Peninsula also, and this little one is greener than it resembles now. And also Antigrande de la Comenda de Igreza provided other three transminerals, two calcites. No, one calcite and two simcates. Not only Antigrande de la Comenda de Igreza, but also Sao Paulo Dois that we have talked before about the fake embers. Also has a very important decorated bead that is also the first important one in size and weight. And we have seen these different patterns and also decorated beads are very rare in Iberian Peninsula. This helps us to avoid this interpretation of just another green mineral to present this could be a special mineral, special consideration of this raw material in particular. We only have the beads and made of fluoride, but we also have two examples of archeological use of mineral of fluoride. But curiously, in the pro-instruction theory, yes, but not provided any fluoride bead. We have very large fragment of green fluoride that you can see here, Bill, with 90 grams, practically. Thank you. And another fragment, maybe a prism of fluoride, green fluoride, too, in Balenciaga Concepción, very well-known thermilinear site, with only one gram, it's not interesting. But they are the only examples used in archeological context, both of the thermilinear. And Cualano-Morquero is a tholos that is very well-defined chronologically, also has the bakers and that. And they are the only two examples that we have recorded till now in the Green Peninsula of fluoride minerals used in archeological context of the late British. Other raw materials that we have identified in this pursuit of transatlantic minerals are calcites that are also used in the late British history vials, in the form mostly of metallic items, special items, mostly in Portugal that we have. Some translucent idols also, et cetera. Silicates that are also frequent in crystallic ornamentation, in the form of micas, et cetera, but are more scarce in translucent forms. And also quartz is the most common mineral in the earth, but we don't have practically any bead made of quartz, but we have a very large set of assemblies in rock-tree-cell and quartz in every context in the Green Peninsula also, but using quartz as a very common leaky provider, not as ornament. There are the spectra of calcite that we have identified in some cases, just for exemplified. Example of silicates and quartz beads that we have characterized both in Portugal, the spectra of the quartz beads of Sao Paulo that we have also resembled. And according to the performing analysis, we have recorded three to three flawed beads, 10 calcite beads, seven quartz beads, five silicates, and 17 undefined in terms of the beads that weren't preserved until now or are in lost collections, are in very restrictive museums, et cetera. Or also this, where we can find this set of materials. We also have a very important problem with the chronological approach to these materials, because usually they don't have, for instance, chronological association with materials or for instance, chronological association with context or whatever. But we can assemblage these materials with the transition of the fourth thermal linea mostly and also to the middle part of the thermal linea due to its natural, most of the context were megalithic monuments, ortho-static megalithic monuments that are 40 examples of 40 sites of megalithic monuments, eight natural keeps with long recuperations, primary recuperation from the laniolithic to the late calcolific. And also we have two contexts that are not funerary, that are beyond Ova de Sao Pedro and Leseia, both are calcolific 45 sites, very well known in the Tagus basin, that also provided one flooring bead each one. As last conclusions, as the first approach to this problematic independent insular, we can affirm that probably flooring had a special consideration in the circulation of raw materials for making ornaments due to its nature, to the chance of sand and visual appearance, and also these strange colors being purple that can be seen. But also for these four sands and charmol smith sand properties that are exclusive from the flooring. Other minerals have also been in the fight. It's a very limited range anyway. Other quartz, calcium, muscovites, et cetera, silicates. But with a very scarce representation on the archaeological record. The inventory that I have talked about before, from the only eight sites known to now in the very peninsular with flooring tournaments, we have provided 53. So it was necessary to make these approaches to raw materials in all contexts revisited. The consumption of flooring, as if you remember the map, is mostly Atlantica in the northern part of Tagus river that in the southern part of the Tagus, in the Setúbal Peninsula, seems that the circulation of flooring could be came in for the northern part of Sierra Morena, to the western part, sorry, of Sierra Morena, of course. And we are trying to evaluate now this issue of prominence, but seem that it's another circulation. The same cases in the Wallachia we are basing. These cases are presented with minerals and are close also to geological off-crocks of flooring. So we can discard this local use also. And Tagus is also exempt for this proximity to geological sources of flooring, that we think that also Tagus basing for some external amount of exotica and ivory, embers, et cetera, that can be as help us to affirm the extraordinary presence of these materials supports the special consideration of flooring. As I have said, most also the context studied here are important monuments, important funerary context with very large amounts of exotica or very considered prestige innovations or prestige boreos or prestige items, et cetera. Between them, we have find these transduced beads. And as I have said, the chronological mark of these transduced beads regards the last part of the Port Milenia in the middle of the third one. The only evidence we have recorded here in the Grand Peninsula concerning the Bronze Age is in the Argyric area and are two flooring beads that are in the town of 117 in Fontana. It's a very important site also of Argyric culture. This is the only example we have till now of floric consumption here. If I don't mind, there's also a floric bead in Belgium also for the second millennia. So we can also establish this continuity or symbolic continuity in the early Bronze Age from the transduced minerals. So thank you very much for your attention. I'm for questions.
