 Rare beds containing Crandolite, a CaL phosphate enriched in senior and Ba, were found within otherwise monotonous cleric lecustrine sediments of the most basin in the Central European Neo-gene or Rift system. These beds were formed at specific times and trace element and organic geochemistry, Heryar geochronology and CO-senior isotope systematics were used to infer their source and processes leading to their formation. The most enigmatic aspect of the formation of these Crandolite beds is the removal of a huge amount of phosphorus from its biogenic cycle in the lecustrine system, which was otherwise stable for Ca0.8 mi. Formation of detritus poor Crandolite beds could result from exceptional environmental disruptions that hindered transport of fine clastic material to the basin floor. Solicic volcanic activity in the area of the Pinonian basin could have triggered this disruption. Crandolite could provide evidence of long-lasting droughts and acidification of the exogenic environment as they are roughly co-evil with the onset of the Miocene Climatic Optimum at Ca17.0 ma.
