Low-temperature geochemical characteristics of ore-forming fluid in the dachang Sb deposit, Qinglong, Guizhou Province, China

摘要

The samples were collected from the Dachang, Gulu, Xishe and Hou0po prospects of the deposit and the minerals for fluid inclusion studies include stibnite and its associated minerals quartz, fluorite, barite, pyrite, calcite, etc. Based on systematical studies by the authors, the data have been obtained on the shape, size and vapor/liquid ratio of 615 fluid inclusions, the homogenization temperatures of 176 fluid inclusions, the salinities of 49 fluid inclusions, the decrepitation temperatures of 20 fluid inclusions, the chemical composition of 8 fluid inclusions and the hydrogen and oxygen isotopic composition of 3 fluid inclusions. On the basis of the above data, this note discusses the low-temperature geochemical characteristics of the Dachang deposit.
