##tihuan2##The mine area consists mainly of carbonate rocks; however, mineral constituents of tailing soil and sediments near the mine were mainly composed of quartz, mica, feldspar, amphibole, calcite, dolomite, magnesite, and clay minerals. Units I and II are characterized by high abundances of siderite, locally pyrite, and dolomite.

##tihuan2##This sample of dolomite is labeled as "cobaltian", presumably implying that the color arises from inclusion of a small amount of cobalt. The sample is about 8x8 cm and is from Tsumeb, Namibia. Impurities and inclusions can have a dramatic effect, as this dark dolomite sample from Pinal County, Arizona shows. The sample is about 11x8 cm.
