【摘要】 个旧锡矿是我国重要的锡矿产地之一,塘子凹矿段位于个旧矿区老厂矿田的西北部。通过对该区开展的一系列野外地质调查研究,结果表明:塘子凹矿段矿体的产出严格受矿区地层、构造、岩浆岩体及围岩蚀变的控制,特别是花岗岩体突起对矿体控制作用较为明显。本文通过对研究区成矿地质特征的综合厘定,总结了该区找矿标志,为后续开展地质找矿指明了方向。更多还原

【Abstract】 Gejiu tin deposit is one of the most important tin deposits in China. Tangziao ore section is located in the northwest of Laochang ore field in Gejiu mining area. Through a series of field geological investigation and research in this area,the results show that the occurrence of ore bodies in Tangziao ore section is strictly controlled by strata,structures,magmatic rock bodies and wall rock alteration,especially the granite outburst. Based on the comprehensive determination of the metallogenic geological characteristics of the study area,this paper summarizes the prospecting indicators of the area,and points out the direction for the follow-up geological prospecting.更多还原
