In sedimentary dolostones, dolomite is most often associated with calcite, aragonite, gypsum, anhydrite, chert, and halite. 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.

Karst bauxite is a major source of aluminum and contains high concentrations of trace elements such as Li, Ga, Sc, and rare earth elements (REEs). It is regarded as a potential non-conventional REE source due to the increasing demand for REEs. This study provides new mineralogical and geochemical evidence of a Lindai …

Dolomite, CaMg(CO 3) 2, is an abundant carbonate mineral in ancient rock formations, but it is extremely scarce in modern sedimentary environments.This intriguing observation has been repeatedly referred to as the "dolomite problem" in the geological literature. Many geoscientists over time have almost obsessively searched for a solution …
