摘要
Silicified tuff spreading over the whole Qinglong antimony deposit is a common product of mineralization in Guizhou Province. Indicated physical and chemical characteristics of ore-forming fluid were studied by comparatively analyzing REE and HFS elements’ parameters of unaltered tuff, silicified tuff, Emeishan basalt, stibnite and fluorite. Ore-forming fluid is characterized by lower REE, higher F-and reducibility. The ratios of Y/Ho, Zr/Hf and Nb/Ta indicated the polyphyleticism of ore-forming fluids. The REE patterns were significantly different from other antimony deposits’. Its W-type tetrad effect was the preference of the fixation of seawater or groundwater REE onto sedimentary rocks.
