在巴什基里亚的几个矿区——锡拜、巴依马克、布里拜——从事的研究,重点是查明隐伏矿床预测的必要因素,有如:在容矿火山岩层的地质剖面上,在矿区与矿田的构造上,以及在围岩热液蚀变晕中含铜黄铁矿矿体的分布规律.现将研究确定的若干基本规律介绍如下:在马格尼托哥尔斯克大复向斜范围内,含铜黄铁矿矿床赋存于细碧角斑岩(钠流纹玄武岩)建造的志留纪和中泥盆世火山岩系中.不同成分岩层的接触带,经常是辉绿岩与英安玢岩的接触带,以及火山碎屑岩层对硫化矿分布最为有利.含矿火山岩系被中、
Research conducted in several Bashkir minefields, namely, Sibai, Baymar, and Buriwi, has focused on identifying the necessary elements for the prediction of a concealed deposit, such as in the geological profile of a volcanic ore-hosting layer , In the mining area and ore field structure, and in the surrounding rock hydrothermal alteration dizzy copper-bearing pyrite ore body distribution law now to determine the number of basic rules introduced as follows: In Magnitogorsk Within the scope of the large syncline, the copper-bearing pyrite deposits occur in the Silurian and Middle Devonian volcanic families built by the Penicillian porphyry (sodium rhyolite basalts), and the contact zones of different compositional strata are often The contact zone between diabase and Yinganlun rock, and the pyroclastic layer are the most favorable for the distribution of sulfide ores.
