Depositional model for the Lower Miocene mixed carbonate-silicilcastic ramp system from the northern Falcón Basin showing the lateral distribution of the different facies domains and their main biogenic components. The facies boundaries are marked by changes in sedimentary conditions (e.g. photic conditions, siliciclastic input, energy, depositional profile). The facies boundaries can be transitional or sharp depending on the gradual or abrupt nature of the changes in sedimentary conditions. The deltaic facies correspond to the Patiecitos Formation, the platform carbonates to the San Luis Formation and the basin turbidites and marls to the Pedregoso Formation. D= Delta, UR= Upper Ramp, (P)MR= Proximal Middle Ramp, (D)MR= Distal Middle Ramp, LR= Lower Ramp, BF= Basin Floor.

Calcite - Mineral Properties, Photos and Occurence Overview of calcite mineral physical properties, structure and its origin and occurence in nature.

A full 2% of the Earth's crust are made of #Calcite. There are over 2000 crystal shapes described, which makes it super popular among collectors.
