江西赣南锡矿床地质特征与前景

The Geological Character and Prospect of Tin Deposits in South JianXi

江西赣南是驰名中外的锡钨矿区．在论述锡矿成矿区域地质背景的基础上，根据矿床地质特征将本区锡矿床划分为：石英脉型、斑岩型、云英岩型、砂锡矿型，此外尚有变花岗岩型和伟晶岩型．对石英脉型锡矿又进一步划分为三个亚型，即富锡外接触带细脉带亚型、富锡的外接触带大脉带亚型和含锡的石英脉亚型．本区最具工业意义的是石英脉型锡矿与斑岩型锡矿．并对它们的找矿前景进行了论述．

South JianXi is rich in tin and wolfram deposits. On the basis of analysis of theregional geology background, according to the geological character, the tin depositswere devided to different types, i. e. quartz vein tin deposit, prophyry tin deposit,gresenization tin deposit, sandy tin deposit and so on. Quartz vein tin deposit alsocan be subdevided three subseries, i. e. rich tiny great quartz veins located inoutside the contact zone, rich tiny quartz veinlets located in outside the contactzone and bearing tin quartz vein belts. Quartz vein tin deposit and porphyry tindeposit were the most significant deposit in industry. The oreforming prospect isdemon straied at last.
