大水沟楚碲铋矿的产状及其文像矿物形态既有普遍的“交代”现象,也有明显的“出溶”特征。文像磁黄铁矿与伴生或残余的磁黄铁矿成分的相似性,以及文像矿物在分布和成分上与出溶动力学实验以及理论模式的差异,表明形成显微文像结构的根本原因为富碲、铋流体交代早期磁黄铁矿。楚碲铋矿及其显微文像结构的特征取决于交代环境的“封闭”程度:强度弱、无铁带出的交代形成具明显“交代”特征的楚碲铋矿;当交代强度大、环境封闭时,交代残余矿物在交代流体中发生“溶解”,形成的文像结构往往具有“出溶”特征。
The occurrence of the telluride-bismuth ore in the Dashuigou and its mineralogical and mineralogical forms are not only common to the “account” phenomenon, but also have obvious “dissolution” characteristics. The similarity of the textural pyrrhotites to the associated or residual pyrrhotite and the differences in the distribution and composition of the textual minerals from the kinetic kinetics and the theoretical models indicate the fundamental basis for the formation of the microscopic imagery The reason for the rich Tellurium, bismuth fluids account for the early pyrrhotite. The characteristics of the telluride bismuthinite and its microscopic imagery structure depend on the degree of “closure” of the account environment: the intensity is weak, and the account of the absence of iron forms a clear “accountable” feature of the telluride bismuth ore; When the environment is closed, the account of the residual minerals in the replacement fluid “dissolved”, the formation of the image structure often has a “dissolution” characteristics.
