| 摘 要： | 半边街硼矿床赋存于大义山北体接触带盐湖向斜西翼,自下而上发育10个矿体,矿体形态、规模、矿石矿物组分和化学组分、B2O3品位呈规律性的变化。通过对矿床特征的研究,认为矿床受地层岩性、构造、岩浆岩等控制。中石炭统大浦组富含MgO、CaO,为区内主要赋矿层位,为成矿提供了丰富的硼沉淀剂。大义山花岗岩北体富含B2O3、Fe2O3以及稀有元素Mn、Ti、W、Sn、Mo、Cu、Pb、Zn等,为成矿的主要物源和热源。构造控制了矿体的产状、形态,为成矿提供了定位空间。

| Abstract: | The boron depsit of Banbianjie is hosted in western limb of Yanhu syncline in Dayishan granite body. There are ten ore bodies from below to above in the area. The morphology,size,mineral and chemical compositions and tenor of B2O3of ore all change regularily.With study on characteristics of deposit and analysis of ore-controlling factors,it is believed that the deposit is controlled by lithostratigraphy,structures and magma etc.The Dapu formation rich in MgO and CaO is the main hosted horizon and provides l... |
