Dolomite minerals

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.

The dolomite bands at 562 and 545 Ma also exhibited similar REE characteristics, with low ∑REE and weak fractionation between light and heavy REEs. They also displayed distinct negative anomalies in Ce and Eu, indicating similar distribution patterns. These findings suggested that formation of the banded hydrothermal dolostone occurred during ...Jul 5, 2021 · Dolomite can form as a major mineral component of marlstones and limestones and is an important sink for magnesium in the marine environment.
