Vein deposits of dolomite occur with quartz and other common vein minerals, such as calcite, magnesite, fluorite, siderite, and sphalerite, or with metallic ore minerals such as galena, pyrite and chalcopyrite. Clastic sedimentary rocks are subdivided on the basis of grain size. Secondary characteristics used to further distinguish clastic rocks are sorting, grain shape, and grain composition. Grain size: Clastic sediments are distinguished on the basis of average grain size. gravel-size particles are larger than 2 mm diameterDolostone. Dolostone is a fine-grained sedimentary rock composed primarily of dolomite, a calcium and magnesium carbonate mineral. Dolostone is similar to limestone and is in some cases formed secondarily from chemically-altered limestone.
