Carbonate Sequence Stratigraphy

Carbonate sequence stratigraphy is the study of layered carbonate rocks, like limestone, to understand how they formed over time. It examines how changes in sea level, climate, and sea chemistry cause shifts in the deposition of carbonate sediments—like reefs and shoals—creating distinct sequences. These layers reveal patterns of natural events such as transgressions (sea levels rising) and regressions (sea levels falling). By analyzing these sequences, geologists can interpret Earth's past environments, predict where valuable reservoirs like oil might be found, and better understand the history of sea changes over millions of years.
