摘要
山东辽上金矿床属于胶莱盆地东北缘,与土堆金矿、蓬家夼金矿、南果子金矿等矿床具有较一致的成矿地质背景条件。本文研究表明,辽上金矿床的形成不仅与古元古代荆山群和新元古代玲珑片麻状石榴子石二长花岗岩的接触部位有关,而且与古元古代荆山群和中生代石英二长闪长岩的接触部位有着密切的关系,今后的找矿勘查工作要注重蚀变石英二长闪长岩的找矿研究工作。
The Liaoshanggold deposit of Shandong province belongs to the northeast margin of the Kuang Basin, and has a consistent metallogenic geological background condition with the deposits such as Tudui gold deposit, Penjiachuan gold deposit and Nanguozigold deposit. The research in this paper shows that the formation of theLiaoshang gold deposit is not only related to the contact parts of the ancient Jingshan group of Guyuan and the ancient granite of the new Proterozoic, but also to the contact parts of the ancient Jingshan group of Guyuan and the Mesozoic quartz two-length diorite, In the future, the prospecting and exploration work should pay attention to the prospecting research work of the altered quartz two-length diorite.
