 I'll now go through the answer of what happened here. So basically down here we have a slate. This would have started off as something like a mudstone deposited underwater. Then we have this quartzite layer and that might have started off as like a sandstone with lots of quartz clasped in it. And then we have more mudstone on top of that. So that would have originally been deposited horizontally. And then we would have had compressional, those units would have been subjected to some compression which would have caused this folding and the metamorphism of these rocks. So the mudstone would have transformed into the slate. The sandstone with quartz rich clasped would have transformed into the quartzite. And yeah, so then we formed this. Then after that we had this granite body which intruded into these metamorphosed slates and quartzites. And so this granite doesn't really have the same like folded fabric as this stuff. So we know that it must be younger than what it's intruding into. Then all of this would have been eroded to create this unconformity here. So this represents a gap in time where we have rocks being lost from the geological record. After that we would have had the deposition of these round clasts which formed the conglomerate and the deposition of calcium carbonate material which would have formed the limestone. Then all of this, you can see that all of this stuff is tilted, right? So then what would have happened next is these sediments that were originally horizontal would have been tilted like this. Then it would have been eroded away to create another unconformity. So we have this surface where the tilt of the beds underneath it is different from above. So that's another place where we have sediments being lost from the geological record. Then we would have had sandstone being deposited on top and making up the sandstone would have been lithified. Then we had erosion. The very final thing to have happened here is this basaltic intrusion which came up and cut through all of these layers. So this is the youngest unit here. So that's the relative sequence of events that happened here. I just want to remind you again that this is what geologists all around the world did to create that geological time scale that you've seen. It's this process, looking at rocks all around the world using cross-cutting relationships and just basic knowledge about sedimentology to determine what are the youngest rocks in Earth, what's the story of what happened all throughout the history of the Earth.
