摘要
桂北一洞锡多金属矿床为一主要产出于基性岩体中的锡矿床。原生锡矿石类型主要为锡石—云英岩型,锡石—电英岩型,锡石—石英型、锡石硫化物型及部份纤维状锡石。对各类型矿石中锡石进行微量元素,稀土元素地球化学及其标型特征的研究,有助于进一步理解锡石形成物质来源,锡矿成因类型划分等问题。
The tin complex deposit at Yidong, Guibei is a tin deposit originating from bedrock. The original tin deposit is classified into the following main types: microhardness, reflectivity,crystal structure,sulphide and partial fibre-like. In order to have a further understanding of the tin-forming substance and the classification of the tin ore genesis, the trace element, the geochemistry of rare earth of cassiterite in varion types of ore deposit and its characteristics are studied.
