How are caves in C.R formed?
” Speleogenesis is the word used by those who study caves to refer to the origin or way the caves were formed. As we said, most causes in C.R happen to develop in limestone rock. As said, limestone, is the consequence of deposition, in shallow seas, of billons of sediments, bones and marine shells of all type, from microscopical to corals, large fish, etc, when C.R haven’t even been formed. The largest mineral present was calcite, that is, CACO3, that is, limestone. Eventually, this layers emerged (were pushed out) out of the sea-bed by tectonic action. (the Earths surface is composed of large “blocks” that float and move, and their interaction is called tectonism, largely associated with earth quakes). In C.R, we have limestone as old as the upper Cretaceous (Sta. Elena Peninsula and near byes of Golfito, higher than 80.000.000 years old. But the majority of our limestone lies between upper Eocene (South + Central Pacific) and Eocene-Oligocene (Barra Honda and Tempisque area ) and Mio
