论文部分内容阅读
徐国风同志在五六年第七期“地质知识”上发表的“和拉尔钦科矿床专家野外工作两个月的体会”一文,我已详尽的读过数遍。因为我是搞汞矿矿山地质工作的,所以愿就文中所谈及的汞矿地质部分,谈谈自己粗浅的看法,不当之处请同志们批评指正。 1.湘黔边界汞矿床的控制成矿主要因素是“页岩顶盖”作用,这样说法我也认为根据不够的。因为:(1)汞矿的产出是多层的,一般在“页岩顶盖”之上的层位仍有汞的产出,并且在主要含矿层位以下的层位还有页岩和泥灰岩的广泛分布;(2)产汞的主要含矿层位并非直接在页岩的复盖
Comrade Xu Guofeng’s article entitled “Experience in Fieldwork for Two Months with Experts of Larkinchko Deposit Experts” published in the Seventh National Geological Knowledge in May-June, I have read in detail several times. Because I am engaged in the geological work of mercury mine, I would like to talk about the geological part of the mercury mine, I talk about my superficial view, and my comrades please correct me criticism. 1. Hunan and Guizhou border mercury deposits control the main factor of mineralization is the “shale roof” effect, so I think the argument is not enough. Because: (1) Mercury production is multi-layered, mercury production is generally still above the “shale roof” and there are shale layers below major ore-bearing beds The widespread distribution of marl; (2) The main ore-bearing beds of mercury are not directly covered by shale
