The primary source of the calcite in limestone is most commonly marine organisms Some of these organisms can construct mounds of rock known as reefs building upon past generations Below about 3 000 meters water pressure and temperature conditions cause the dissolution of calcite to increase nonlinearly so limestone typically does not form in deeper waters see lysocline
