摘要
个旧锡矿是中外著名的锡产地 ,其年产量占全国 4 0 %以上 ,过去很多学者对此提出花岗岩成因观点。目前 ,最新的研究成果认为是多成因、多期次叠加改造的层控矿床。本文在概述玄武岩分布特征的基础上 ,重点研究了玄武岩岩石的化学特征、微量元素特征、稀土元素特征 。
The tin mine in Gejiu is the famous tin producer both at home and abroad,with its annual capacity taking up over 40% of that of the whole China.In the past,many scholars put forward such viewpoint that granite was the genesis of the mineralization.However,the latest research shows that it is the stratabound ore deposit which has been formed and transformed with many geneses and secondary superimposition in several phases.On the basis of analyzing the distribution of basalt,this paper mainly discusses the characteristics of all the basaltic geochemistry,microelements and thulium,as well as the relationship between basalt and its mineralization.
