胶莱盆地超大型金矿床成矿可能性研究

Study on possibilities of forming super-huge gold deposit in Jiaolai Basin

胶莱盆地已知金矿床均属下白垩统莱阳群一段烃金双源层为矿源层的层控金矿床。本文通过矿源层、构造作用、生物成矿作用、水源及热源等方面研究 ,说明胶莱盆地具备形成层控超大型金矿床的条件 ,而崖子地区是寻找该种超大型金矿床的首选找矿靶区。

The known gold deposit in Jiaolai Basin all belong to stratabound gold deposit in the first member of the Laiyang group of the Lower Cretaceous series with hydrocarbon gold two source as their bed source.In the paper,from the study on source bed ,tectonoprocess,biomineralization process,water source and hot source etc,it shows that there is the condition forming stratabound super huge gold deposit in Jiaolai Basin and Yazi district is the most important prospecting target searching for the type of super huge gold deposit.
