摘要
Dongguashan copper deposit is one of representative stratabound skarn Cu deposits in Tongling, Anhui Province, and pyrrhotite is a type of ore minerals widely distributed in the deposit. Field investigation and microscopic observation indicate occurrence of sedimentary, thermally metamorphic, and hydrothermal metasomatic textures and structures in pyrrhotite ores from the deposit. Mineralogic study shows large difference in composition of pyrrhotite from the different ores, with Fe content ranging from 57.78% to 60.67%. There occur hexagonal (high-temperature) and monoclinic (low-temperature) pyrrhotite mainly formed by desulfurization of pyrite.
