论大宝山矿床成因

通过对大宝山矿区各矿床产出的地质环境，矿体产状，矿石类型和结构构造，矿石稳定同位素特征，稀土元素特征，成矿温度等方面的研究，论证矿区的成矿历史分２个成矿期，４个成矿介段，即中泥盆世多金星成矿期的铜铜锌银硫化物成矿阶段，菱铁矿成矿阶段；早白垩世铁钼钨成矿期的铁钨成矿阶段，钼钨成矿阶段，各阶段均有各自的成矿地质环境和成矿方式，构成一个在空间上关系密切，成历上有一定联系，时间上差别明显的矿床系列。

On Genesis of Dabaoshan Mineral Deposits

Dabaoshan mineral deposits are well known polymetallic deposits in China. Based On the analysis on the geologic environment of different deposits origin,occurrence of ore bodies,types,texture and structure of ore and isotopic characteristicsas well as rare earth elements and minerogenetic temperature etc,the history of depositsis divided into two minerogenet ical periods and four minerogenetic stages,they arepolymetallic sulfide minerogenetic stage and siderite minerogenetic stage of middleherohian epoch;Ferberite minerogenetic stage and molybedenum-tungstunminerogenetic stage of Cretaceous period.Each minerogenetic stage has its ownminerogenetic environment and minerogenetic pattern which constitute a closely relationin space and a certain relation in genesis,but quite different in the series of mineraldeposits.
