我队二分队1977年在本区进行1:5万地质普查时,在已往工作基础上,找到了辉长岩及其中的蛇纹石化辉橄岩、硅化滑镁岩等基性—超基性岩露头多处,经采样做光谱分析,发现其含铬、镍、钴偏高。嗣后在地表评价工作中,又陆续见到铬铁矿小矿(化)体数处,并对其岩性、构造和地表矿化特征有了初步认识,这为解决摩天岭区的某些基础地质问题和及找铬矿资源提供了新的信息。笔者将在该区工作期间所获资料予以初步整理,撰写成文,供参考。鉴于工作程度和水平所限,错误之处在所难免,望批评指正。
In 1977, when I conducted a 1: 50000 geological survey in this area, based on previous work, we found gabbro and its serpentinization dacite, silicified magnesia and other basic-ultrabasic Many rock outcrops, by sampling do spectral analysis, found that it contains chromium, nickel, cobalt, high. Subsequently, in the surface evaluation work, they also successively saw the number of small ore bodies of chromite and their initial understanding of the lithology, tectonics and surface mineralization. This is to solve some problems in the Motianling area Geological issues and looking for chrome ore resources provide new information. I will be in the area during the work to obtain the preliminary information collected, writing written, for reference. In view of the degree of work and the level of limitations, the error is inevitable, hope to criticism and correction.
