通过分析胶东地区各地质体的金概率分布模型，金含量的分数维特征、金及相关元素的组合特征等来评价胶东地区各地质体的含金性。结果表明：胶东群、粉子山群、玲珑型花岗岩为金的矿源岩，郭家岭型花岗岩可能既为本区的金成矿提供成矿物质，又起到“热机”的作用。蓬莱群及滦家河型花岗岩提供本区金成矿物质的可能性很小。
By analyzing the gold probability distribution model of the geologic bodies in the Jiaodong area, the fractal features of the gold content and the combination features of gold and related elements, the gold content of geologic bodies in the Jiaodong area is evaluated. The results show that Jiaodong Group, Fenzishan Group and Linglong granite are gold source rocks. The Guojialing granite may not only provide metallogenic materials for gold mineralization in the region but also play a role of “heat engine”. The Penglai Group and Luanjiahe granites are less likely to provide gold-forming minerals in this area.
