黄沙黑钨矿石英脉矿床(图1)是“五层楼”分带模式的典型矿床之一.矿区保有的储量中脉带型矿体约占3/4.但是,有的脉带矿化稳定深邃,有的贫富涨落悬殊.因此,在勘探工作中研究矿体脉幅与品位变化规律,就具有重要的现实意义.兹据工作实践,总结如下. 总脉幅、最大脉幅与矿化富集的关系众所周知,“五层楼”式脉状钨矿矿脉条数和每条脉的厚度都有很大变化.统计资料表明,脉带向下含脉率增高,含脉密度下降;总脉幅中部最大,两端最小,一般呈重
The Yellow Sand Wollastonite Vein Deposit (Figure 1) is one of the typical deposits in the “five-storey” zoning mode, with reserves accounting for about 3/4 of the reserves in the mining area. However, some vein mineralization Therefore, it is of great practical significance to study the law of ore body pulse amplitude and grade during the exploration work.According to the work practice, the conclusions are as follows: Total pulse width, maximum pulse width and The relationship between mineralization and enrichment As we all know, “five-story” type vein tungsten ore veins and the thickness of each pulse has a great change in statistics show that the pulse down the pulse rate increases, including pulse density decreased ; The largest central pulse width, the smallest at both ends, usually heavy
