摘要
本文在前人对区域地质调查的基础上 ,通过对塘子凹矿床成矿特征及规律的研究 ,认为塘子凹锡多金属矿床的成因与中三叠统的大理岩、燕山晚期的淡色花岗岩共同作用有关 ,燕山晚期花岗岩体的空间形态直接控制矿体的产出部位。花岗岩以构造侵位方式侵位于中三叠统大理岩中 ,其空间细部特征受五子山复背斜和南北向隐断裂的作用。指出八处成矿有利部位。
Based on regional geology research, it is suggested that the formation of the Gejiu Tangziwa tin polymetal deposits in Yunnan Province is related to the Middile Triassic lime rock and the Yanshanian terminal tinge granite, and the spatial form of the Yanshanian terminal tinge granite directly controls the mine output position. The granite invaded into the Middle Triassic lime rock in the form of tectonic emplacement and the spatial form controls the Wuzishan complex anticline and the hidden south north direction rupture. Much attention should be paid to the eight places as a avail target in the future.
