云南昌宁薅坝地锡矿花岗岩特征
|
摘要
滇西含锡花岗岩有其特定的时、空分布规律及明显的特征标志。薅坝地花岗岩在岩石学、岩石化学、地球化学特征等方面与滇西典型的含锡花岗岩有所差异,因此常被归为非含锡花岗岩之列。通过对薅坝地花岗岩岩性特征、副矿物特征、岩石化学特征等方面进行重新分析,并将其与世界含锡花岗岩进行对比,同时根据花岗岩对锡矿床的控制因素进行综合评价,得出本区花岗岩为含锡花岗岩的结论。
The tin-containing granite in western Yunnan has its specific temporal and spatial distribution laws and obvious characteristic marks.The granites in Haobadi differ from the typical tin-containing granites in western Yunnan in terms of petrology,rock chemistry and geochemical characteristics.Therefore,it is often classified as non-tin-containing granite.This paper re-analyzes the lithological characteristics,secondary mineral characteristics and rock chemistry characteristics of the granite in Haobadi,compares it to the world's tin-containing granite,according to the comprehensive evaluation of the control factors of granite on tin deposits,conclusion that the granite in this area is tin-containing granite.
