近年来宁夏地矿局第二地质矿产调查队,坚持从实际出发,反复实践,进行了地质、化探以及新技术、新方法应用等综台找矿。于昆仑—秦岭地槽褶皱系走廊过渡带东端的宁夏境内,发现一微细浸染型金矿。该矿明显受层位和构造控制。矿床住往分布在东西向及北东向两组褶皱与断裂复合叠加地带,而矿体则赋存在东西向、近东西向挤压破碎带及其相关的北东向断裂中。含矿围岩为下石炭统碳酸盐岩—碎屑岩建造中的破碎砂岩、粉砂岩、泥岩及碎裂岩中。其次是泥盆统碎屑岩。金矿体常与石英闪长玢岩岩脉紧密伴生,主要矿体展布方向与脉岩走向一致。矿石中金主要以单体自然金状态赋存,呈显微粒状一次显微粒状(0.000n—O.04mm)或各种不同形态微粒金的集合体嵌布于褐铁矿,石英和粘土矿物中。其品
In recent years, Ningxia Geological and Mineral Resources Bureau, the second geology and mineral investigation team, insisted from reality, repeated practice, carried out geology, geochemical exploration, and new technologies, new methods such as comprehensive prospecting applications. A finely disseminated gold deposit was found in the middle of the Kunlun-Qinling terrestrial fold belt corridor transition zone in Ningxia. The mine is obviously controlled by horizon and tectonics. The deposits are distributed in the fold-fault superimposed superimposed zone between the east and the west and the northeast, while the orebodies are distributed in the east-west and the east-west crush and the associated NE-trending faults. Ore-bearing rocks are fractured sandstones, siltstones, mudstones and cataclasites in the Lower Carboniferous carbonate-clastic rock. Followed by Devonian clastic rocks. Gold ore bodies are often closely associated with quartz diorite dikes, and the direction of the main ore bodies is consistent with the direction of the veins. Ore gold in the main monomer to the natural state of gold occurs, was a microscopic particulate (0.000n-O.04mm) or a variety of different forms of micro-gold embedded in the assembly of limonite, quartz and clay minerals in.
