一、前言解放以来,在党的建设社会主义总路线指引下,由于广大地质工作者的努力,已经查明祁连山区是我国超基性岩集中分布地区之一,目前已发现600多个岩体(群),并探明许多岩体赋含有国家急需的多种矿产资源。我室超基性岩组在前人工作基础上,对具有一定矿床规模的野马山大道尔吉含铬岩体、龙首山金川含铜镍岩体、拉脊山上庄含磷岩体的岩石、矿物作了一些实验研究工作。现以这三个不同含矿岩体作为典型,并对区内几个含铬岩体,如托赖山玉石沟岩体、祁连山南带绿梁山南坡岩体等的已有资料进行对比,初步总结了这几个
I. Introduction Since the liberation, under the guidance of the party’s general line for building socialism and due to the efforts of the vast number of geological workers, it has been ascertained that the Qilian Mountains are one of the concentrated areas where ultrabasic rocks are concentrated in our country. It has been discovered that over 600 rock masses Group), and proved that many rock mass contains a variety of mineral resources urgently needed by the country. Based on the previous work of our predecessor, the ultramafic rock group in our laboratory evaluated the characteristics of the ore-bearing rocks, such as the Yikeji-Chromite in the Mustangshan Avenue, the Longshoushan Jinchuan copper-bearing nickel rock, the Shangjiazhuang phosphorous in the Laji Mountain, Minerals made some experimental research work. These three ore-bearing intrusive rocks are typical, and the existing data of several chromium-bearing rock masses in the area, such as the Tuolaishan Yushigou rock mass and the southern slope of the Luliangshan southern slope in the Qilian Mountains are compared. A preliminary summary of these few
