antimony ore nature

Project objectives are to document the origin of the Yellow Pine gold-antimony deposit and, by extension, the origin of this deposit type. Our goal is to understand the structural, tectonic, and magmatic setting of the deposit, the character of the ore-transporting fluids, the conditions of ore deposition, and the regional stratigraphic framework and geochemical ore controls of metasedimentary ...
