近两年来,我们在开展铁铜富矿的普查会战中,在有关单位配合下,究成了大量基础地质工作,发现一批新的铁铜矿产地,矿产储量不断增长.现将某浅变质岩铜矿地质特征及找矿标志,初步整理如下,供作参考.一区域地质概况1.地层分布及岩性特点区内出露地层以会理群为主,为一套巨厚的浅变质岩系;与邻区对比,初步划分为上下两个亚群,七个岩组,十三个岩性段(图1).会理下亚
In the past two years, with the cooperation of the relevant units, we conducted a lot of basic geological work during the census battle of iron-copper-rich mines, discovered a number of new iron-copper ore producing areas, and the reserves of mineral resources have been continuously increasing. Geological characteristics of copper deposits and ore prospecting signs are summarized as follows for reference I. Geological Overview of a Region 1. Stratigraphic Distribution and Lithology Features The exposed strata in the area are dominated by Huili Group and are a set of huge thick metamorphic rocks Compared with the adjacent areas, the area is divided into two subgroups, upper and lower subgroups, seven rock groups and thirteen lithologic segments (Figure 1)
