Sedimentology and Stratigraphy. Most macrofossils can be treated with 1 acid to remove carbonates, and 2 alkali to remove humic acids that might be in the sediment. CrossRef Google Scholar. Carbonate in sediments can come from the natural development of carbonate nodules in the sediment called pedogenic carbonates or from the movement of carbonates that are dissolved out of geologic formations like limestone, marl and other carbonate bearing minerals which are then redeposited into the sediment.
