WebThere are two major ideas on how the Anastasia Formation was lithified. One states that the Anastasia represents ancient beach rock and that the cementation occurred in the tidal zone as seawater evaporated at low tide. WebTwo important steps are needed for sediments to lithify. Sediments are squeezed together by the weight of overlying sediments on top of them. This is called compaction. Cemented, non-organic sediments become clastic rocks. If organic material is included, they are bioclastic rocks.
