     Micrite = lime mud; CaCO3, the mineral calcite. Micrite is the equivalent of clay (rock = shale) in clastics. Originally deposited as microscopic aragonite needles, but now converted to calcite and then calcite cemented to form the rock. See Origin of Micrite for more details.
     This close-up view shows more clearly the uniform composition and conchoidal fracture of the micrite.
