甘肃岷县马坞金矿地球化学特征、控矿因素分析及找矿潜力

Mawu Gold Geochemical Characteristics and Ore-controlling Factors and Prospecting Potential of Min County,Gansu Province

马坞金矿分布于岷-礼成矿带的东部,通过野外地质勘查和1/万土壤地球化学测量,获得了丰富的矿体地质及地球化学测量数据,系统分析了矿床的地球化学特征,围岩蚀变以中-低温热液蚀变为主,蚀变强度与金矿化程度呈正相关,从地质的地层、构造、岩浆岩及地球化学特征方面分析了控矿因素,对找矿潜力进行了分析。

Mawu gold deposits are located in the east of Min-Li ore belt.Through field geological survey and the 1/10 000 soil geochemical survey,we get rich orebody geological and geochemical data,and analyzed the ore deposit geochemical characteristics.Wall rock alteration is mainly in low and middle temperature hydrothermal alteration,alteration intensity is positively related to the gold mineralization degree.The ore controlling factors were analyzed from the geological strata,structure,magmatic rocks and geochemical features.The prospecting potential was discussed.
