Compared with dolomitic limestone and micrite limestone, ... The 87 Sr/ 86 Sr ratio of the oolitic dolomite or micrite dolomite with good primary texture is lower and closer to that of synchronous seawater, indicating the diagenetic fluid in reservoir pore exchanged directly with high salinity seawater in the later time, leading to quick and extensive dolomitization on the surface of carbonate ...

Oolitic Limestone: A limestone composed mainly of calcium carbonate "oolites," small spheres formed by the concentric precipitation of calcium carbonate on a sand grain or shell fragment. Travertine: A limestone that forms by evaporative precipitation, often in a cave, to produce formations such as stalactites, stalagmites, and flowstone.

Lime Mud Or Micrite – Mom's Best Recipes

Micrite is a limestone constituent formed of calcareous particles ranging in diameter up to four μm formed by the recrystallization of lime mud. It is a sedimentary rock formed of calcareous particles ranging in diameter from 0.06 to 2 mm (0.002 to 0.08 inch) that have been deposited mechanically rather than from solution.

Secondary calcite may be deposited by supersaturated meteoric waters (groundwater that precipitates the material in caves). This produces speleothems, such as stalagmites and stalactites. Another form taken by calcite is oolitic limestone, which can be recognized by its granular (oolite) appearance.
