地质找矿过程中实物地质资料的再利用:以贵州省威宁-水城铁多金属为例
发布时间：2019-05-23 03:09
【摘要】：本文简述了贵州威宁-水城地区铁多金属矿的区域地质背景,并对该区自1958年以来的找矿历程及找矿过程中实物地质资料再利用进行了概述。其中实物地质资料再利用起到重要作用的两次找矿突破成果是在1959年和2008年。特别是2008年,通过对铜矿普查项目保存的钻孔岩芯进行了系统的补采化学样和对保存的附样等实物资料重新测试分析,同时在对该区区域地质背景、矿床地质特征及富集规律等进行综合研究的基础上,又发现了该区产出于峨眉山玄武岩顶部的找矿标志层和赋矿有利地段,经过测试分析后发现除了铁元素外,尚含有铜、钛、稀土、铌等丰富的有用元素,这些元素均达到工业品位要求或综合利用要求。至2013年取得了重大找矿突破,提交了铁矿总资源量23 425.69万t,探明总资源储量2 260.72万t。此实例说明,对以往实物地质资料的重复利用与综合研究,在实现地质找矿工作中,常常起到关键作用,是实现找矿突破的有效途径。
[Abstract]:This paper briefly describes the regional geological background of iron polymetallic deposits in Weining-Shuicheng area, Guizhou Province, and summarizes the prospecting process and the reuse of physical geological data in the prospecting process since 1958. Among them, the results of two prospecting breakthroughs, which play an important role in the reuse of physical geological data, were in 1959 and 2008. In particular, in 2008, the physical data such as remining chemical samples and preserved attached samples were systematically tested and analyzed for the bored cores preserved in the copper survey project, and at the same time, the regional geological background of the area was also tested and analyzed. On the basis of comprehensive study on geological characteristics and enrichment law of the deposit, the prospecting marker layer and favorable ore-bearing area at the top of Emeishan basalt are found. After test and analysis, it is found that there are copper and titanium in addition to iron. Rare earth, niobium and other useful elements, these elements meet the requirements of industrial grade or comprehensive utilization. By 2013, a major prospecting breakthrough had been made, with a total iron ore resource volume of 234.2569 million tons and proven total resource reserves of 22.6072 million t. This example shows that the reuse and comprehensive study of physical geological data often plays a key role in the realization of geological prospecting and is an effective way to realize the breakthrough of prospecting.
