地質找礦過程中實物地質資料的再利用:以貴州省威寧-水城鐵多金屬為例
發(fā)布時間：2019-05-23 03:09
【摘要】：本文簡述了貴州威寧-水城地區(qū)鐵多金屬礦的區(qū)域地質背景,并對該區(qū)自1958年以來的找礦歷程及找礦過程中實物地質資料再利用進行了概述。其中實物地質資料再利用起到重要作用的兩次找礦突破成果是在1959年和2008年。特別是2008年,通過對銅礦普查項目保存的鉆孔巖芯進行了系統(tǒng)的補采化學樣和對保存的附樣等實物資料重新測試分析,同時在對該區(qū)區(qū)域地質背景、礦床地質特征及富集規(guī)律等進行綜合研究的基礎上,又發(fā)現了該區(qū)產出于峨眉山玄武巖頂部的找礦標志層和賦礦有利地段,經過測試分析后發(fā)現除了鐵元素外,尚含有銅、鈦、稀土、鈮等豐富的有用元素,這些元素均達到工業(yè)品位要求或綜合利用要求。至2013年取得了重大找礦突破,提交了鐵礦總資源量23 425.69萬t,探明總資源儲量2 260.72萬t。此實例說明,對以往實物地質資料的重復利用與綜合研究,在實現地質找礦工作中,常常起到關鍵作用,是實現找礦突破的有效途徑。
[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.
