摘要:

自然重砂测量是矿产勘查的有效手段之一。然而在实际找矿工作中,目标矿物往往由于其自身的物理、化学特性,在重砂样品中不能得到充分的反映。如何根据所发现的重矿物组合,探寻某些特定成矿模式下有用矿产的存在,充分发挥自然重砂测量在矿产资源调查中的作用是一个值得探讨的问题。从相广锰—银矿床锰、银矿物的赋存状态、富集规律、共生关系出发,试图建立一个适用于华北地台北缘火山热液充填型锰—银矿床的重砂综合找矿模型。

Abstract:

Heavy minerals survey is an effective prospecting. In practice, however, target minerals can not be enough acquired in samples due to their physical and chemical features. How to find deposits according to heavy minerals combination is notable during minerals resource survey. This paper, based on Mn and Ag bearing minerals'occurrence forms, enrichment rules and coexisting relation of Xiangguang Mn-Ag Deposit, establishes a heavy mineral comprehensive prospecting model for volcanic hydrothermal filling Mn-Ag deposits in the northern margin of North China Craton.

Key words: heavy minerals survey, volcanic hydrothermal filling, Mn-Ag deposit, heavy minerals prospecting model, Xiangguang desposit
