Abstract: A typical turquoise mineralization belt is distributed in Ma'anshan City of Anhui Province. The genesis of these turquoise deposits remains controversial. In this study, a detailed field geological survey and indoor observation of the Bijiashan turquoise deposits were carried out. The mineralogy and petro-chemistry of the turquoise minerals were analyzed by using microscope, electron probe, SEM, ICP-MS and other methods. The main minerals of Bijiashan turquoise deposit consist of turquoise with a small amount of quartz, pyrite, feldspars, pyrophyllite, limonite and jarosite. Turquoise is microcrystalline aggregate with gelatinous structure. The SEM micromorphology shows that the platelike crystallite aggregates of turquoise are parallel or staggered. The symbiotic pyrites with turquoise are characterized by medium-low temperature hydrothermal cubes, pentagonal dodecahedron and polymorphic crystal. In the chart of Co-Ni content relationship, the samples mainly distributed in magma and hydrothermal area. The δ34S isotope ranges from 8.3‰ to 11.9 ‰, which indicates that the sulphur was derived from a deep magmatic and sedimentary source, and the ore-forming fluid was formed by mixed atmospheric precipitation and deep magmatic water. Combined with the mineral assemblage, mineral forming sequence, symbiotic pyrite mineralization, and ore-forming fluid, Bijiashan turquoise deposit is a medium-low temperature hydrothermally metasomatic deposit formed by volcanic eruption.

Key words: Bijiashan turquoise deposit, turquoise, mineralogy, isotope, hydrothermal alliteration, genesis of deposit
