摘要
胶东地区存在壳源侵入岩、壳幔源火山—侵入岩两个成岩系列和金矿、多金属矿两个成矿系列。分析了壳源侵入岩与金矿、壳幔源火山—侵入岩与多金属矿的密切空间关系 ,据同位素年龄和产出交切关系分析了它们的时间关系 ,此基础上 ,结合地球化学研究资料和蚀变特征 ,探讨了它们之间的成因关系。
There exist two rock series namely crust caused intrusive rock and crust-mantle caused volcanic-intrusive rock.Also,there are two metallogenic series i.e. gold ore deposit and complex ore deposit series.The close spatial relation between crust caused intrusive rock and gold ore deposit,as well as the spatail relation between crust-mantle caused volcanic-intrusive rock and complex ore deposit are analysed.According to the cross-correlation between isotopic age and output,the temporal relation between them are also analyzed.On the basis of geochemical study and alteration feature,the genetic relations between them are explored.
