根据大水沟楚碲铋矿的产状、“客晶”磁黄铁矿的形态、展布和化学成分 ,其显微文像结构可分成传统意义上的“交代型”、“出溶型”两类 ,但它们形成的根本原因是由于富碲、铋流体在相对封闭环境中交代了早期硫化物 (磁黄铁矿为主 )。交代强度及其环境的稳定程度决定了显微文像结构的特征 :强度弱、稳定性差 ,可形成具明显“交代”特征的楚碲铋矿 ;强度大、环境稳定则早期硫化物在交代流体中充分“溶解” ,形成的文像结构往往具有“出溶”特征。
According to the occurrence of the telluride-bismuth mine in the Dashuigou and the morphology, distribution and chemical composition of the “pyrochlore pyrrhotite”, its microscopic image structure can be divided into “conformational type” in the traditional sense, “dissolution type ”However, the fundamental reason for their formation is that the tellurium and bismuth fluids account for the early sulphide (mainly pyrrhotite) in a relatively closed environment. The strength of the accountability and the stability of its environment determine the characteristics of the microscopic textural structure: weak strength and poor stability, and can form the Chu-telluride ore with the obvious “metasomatic” characteristics; and when the intensity is high and the environment is stable, Fully “dissolved”, the formation of the image structure often has a “dissolution” characteristics.
