Crystalline dolostone is common and subdivided into three types according to the size of dolomite crystals. Dolomite crystals in the micritic dolostone mostly range in size from 5 to 20 μm, with some larger crystals (Fig. 4a, b). The main pore types comprise gypsum-mold pores (Fig. 4c), dissolved pores, and vugs formed by the karst.A) breccia has a compacted, clay-rich matrix; conglomerate has no matrix. B) breccia clasts are the size of baseballs; conglomerate clasts are larger. C) breccia clasts are angular; conglomerate clasts are rounded. D) a breccia is well stratified; a conglomerate is poorly stratified. Grain size is determined by the level of metamorphism. There are more durable hard varieties used in machine construction, and some have the desired fine particle size for high carvings. 8,000 years ago, Native Americans used the rock to make carved sculptures and cooking pots.Mar 1, 2017 · By grain size, the crystalline dolomite could be subdivided into the dolomicrite, the silty dolomite, and the fine-crystalline dolostone, and so on. 4.1.1 .
