云南上厂铁矿控矿因素分析

Ore-controlling Factors Analysis of Shangchang Iron Mine in Yunnan Province

云南上厂铁矿区上部为堆积型赤铁矿床,其矿体厚度及规模等主要受三叠纪前后两次侵入夷平和冰川作用等控矿因素控制,而矿区深部原生脉矿的矿体则受成矿前后的两组断裂所控制。在开展矿区深部及周边找矿时,应根据不同矿种及其相应的控矿因素进行综合分析,才能达到较好的找矿效果。

Accumulation ore on the upper part of Shangehang iron mine in Yunnan, orebody characteristics such as size and thickness are mainly controlled by two ore - controlling factors of the Triassic period before and after twice invaded - flattened and glacial action. But the characteristics of deep primary ore are controlled by two groups of the ore - forming faults before and after mineralization. In the prospect for the ore deposit＇ s deep and surrounding area, it should according to the different minerals and its corresponding ore - controlling factors comprehensive analysis, to achieve satisfactory ore - prospecting results.
