近年来我区在锡石-硫化物型锡矿床普查找矿方面,利用黄铁矿化、磁黄铁矿化标志,无轮对盲矿体的寻找和对暴露出地表含矿破碎带的查明,都获得比较令人满意的效果.本文仅是黄铁矿化、磁黄铁矿化的性状及其在普查找矿中应用的某些认识和点滴经验的概括.一、矿田地质概述矿田处于古陆西南缘,呈北北西向断陷带中的复式褶皱中.褶皱背斜中有自北东推向南西的逆掩断层和若干垂直于轴向的横断裂.地层主要为泥盆纪的灰岩建造与矽质页岩建造,其上覆以石炭二迭纪的灰岩建造和三迭纪的页岩建造.
In recent years, our area in cassiterite-sulfide tin prospecting prospecting, the use of pyrite, pyrrhotic signs, no round of blind ore body and to reveal the surface ore-bearing fractured zone investigation Ming, have been more satisfactory results.This article is only pyrite, pyrrhotic traits and prospecting in general exploration of some of the knowledge and bit by bit experience in general. The ore field is located in the southwestern margin of the ancient land, which is in the north-west-west fault zone. The fold anticline consists of the overthrust that thrusts from the north to the southwest and several transverse faults that are perpendicular to the axis.The strata are mainly mud The basin was built of limestone and siliceous shale, overlain with limestone dating from the Permian and Permian shales.
