在寻找和评价隐伏、半隐伏裂隙充填型钨矿时,石英云母线作为一种地表可见的找矿标志,正越来越多地引起人们的重视。为提高找矿效果,现以某矿床为例,谈谈“石英云母线”的应用。一石英云母线的赋存部位本文所述矿床产于中—上寒武统变质砂岩、板岩中,是一个大型、构式较完整的“石英细脉带型”钨锡矿床。部分工业矿体出露地表,下部有隐伏的花岗岩体。石英云母线明显地存在于矿床顶部、矿体两端,而矿体两侧希少。二石英云母线的特征 1.石英云母线的走向、倾斜与矿体基本一致。 2.一条石英云母线的宽度,一般在1厘
In the search and evaluation of buried and semi-buried fissure-filled tungsten deposits, quartz mica as an indicator of prospecting on the surface of the earth is attracting more and more attention. In order to improve the ore prospecting effect, we take a deposit as an example to talk about the application of “quartz mica”. Occurrence Site of a Quartz Mica Line The deposit described in this article is a large and structurally complete “quartz vein-type” tungsten-tin deposit hosted by the Middle-Upper Cambrian metamorphic sandstone and slate. Some industrial ore bodies exposed the surface, the lower part of the concealed granite body. Quartz mica clearly exists at the top of the deposit, both ends of the ore body, while the ore body is less on both sides of the ore body. The characteristics of the two quartz mica 1. The direction of the quartz mica, tilt and ore body basically the same. 2. The width of a quartz mica wire, usually 1%
