Origin Of Carbonate Sedimentary Rocks Pdf New Review

Understanding origin directly impacts exploration:

Unlike siliciclastic rocks, which originate from the weathering of pre-existing mountains, most carbonate rocks are born within their basin of deposition. They are fundamentally "extrabasinal" in chemical origin but "intrabasinal" in physical form. In modern environments, the primary drivers are calcifying organisms. Corals, mollusks, and calcareous algae extract calcium and bicarbonate ions from seawater to build skeletal structures. Upon death, these skeletons break down into grains ranging from large bioclasts to microscopic lime mud. origin of carbonate sedimentary rocks pdf new
