摘要
纳赤台脉石英矿床位于东昆仑成矿带,该矿床产于昆南断裂发育的次级构造,脉石英品质较好,矿石呈白色—乳白色,块状构造,SiO2 含量 98.8%～99.63%,认为纳赤台脉石英矿床属于中低温岩浆热液型矿床.本文通过总结纳赤台脉石英矿床地质特征、矿体特征、矿石质量及结合测试数据分析矿床成因.旨在为该区域寻找同类或类似的脉石英矿提供指导.
Abstract
The Nachitai vein quartz deposit is located in the eastern Kunlun metallogenic belt.The deposit is located in a secondary structure developed by the Kunnan fault.The quality of the vein quartz is good,and the ore is white milky white,with a block structure and a SiO2 content of 98.8%to 99.63%.It is believed that the Nachitai vein quartz deposit belongs to a medium low temperature magmatic hydrothermal type deposit.This article summarizes the geological characteristics,ore body characteristics,ore quality,and analyzes the genesis of the Nachitai vein quartz deposit by combining test data.Intended to provide guidance for searching for similar or similar vein quartz deposits in the region.
