daryl stewart Micrite is one of the most common carbonate rocks. Most of what people call " limestone" is largely or exclusively micrite. As with clay (shale) it is deposited in generally quiet water, and appears in any environment where those conditions exist. Often we associate quiet water with deep water, where waves and currents do not touch bottom. michele leatherskansas ranked C'est une roche biomicrite (calcaire à micro-organismes et à grain fin), friable et poreuse.
