南戈滩地区成矿条件研究

Research on the mineral formation condition of Nangetan area

通过对青海省都兰县南戈滩地区构造、地层、岩浆岩及变质作用等地质因素的分析,并结合区内多金属矿化点带特征,讨论了地层、构造、岩浆岩、变质作用等与矿化关系密切的因素,运用成矿预测理论,预测南戈滩地区主要矿种的矿化特征,总结出南戈滩地区多金属矿化的特点以及控矿的主要因素,说明了南戈滩地区具有较好的多金属成矿前景.

This paper aims to predict the general characteristics of major minerals ore from Nangetan area by using Metallogenic prediction theory through the analysis of structure,stratum,magmatic rocks,metamorphism and other geologic factors,combined with the specific characteristics of mineralization belt,and the relationship between structure,stratigraphy,lithology and ore forming conditions.The polymetallic ore characteristics and ore control factors of Nangetan area have been presented.It shows that this area has bright prospects for metallization which gives references to ore prospecting in the future.
