新一轮就矿找矿

摘要

A new round of making ore search nearby is proposed in this paper based on previous prospecting history from 1950’s to 1960’s. The new round of making ore search nearby has its new characteristics. Deep prospecting is a type of making ore search nearby. Crustal Continuum Model, deep fluid function (mineralization), and metallogenic level provide a theoretical basis for the new round of making ore search nearby. Success in ore prospecting was achieved both in China and abroad, especially in Hunan Province. This paper sums up some experience of deep ore prospecting criteria in three aspects, i.e., minerals and mineral assemblages, granite metallogenic specialization indicators, identification of mantle-origin deposit marks. In addition, identifying the deep mantle source marks of ore-forming fluids, strengthening the study of the metallogenic regularity, updating the concept, and the introduction of new technology and new method deserve much attention in the actual deep ore-prospecting work.%本文简要回顾了二十世纪五、六十年代就矿找矿的历史，进而提出新一轮的就矿找矿。相比之下，新一轮就矿找矿具有新的特点。深部找矿实则是一种就矿找矿，地壳连续成矿理论、深部流体(成矿)作用理论、成矿台阶理论都为新一轮就矿找矿提供了理论依据。深部找矿在国内外初显成效，湘中地区亦有很多成功案例。本文从3个方面总结了深部找矿的一些经验标志，即矿种及矿种组合系列标志、花岗岩成矿专属性标志、幔源成因矿床的鉴别标志。此外，辨别成矿流体的深(幔)源标志、加强成矿规律研究、更新观念、引进新技术新方法，都是实际深部找矿工作中需要注意的。
