摘要
胶东是我国著名的金矿集中区,焦家金矿是胶东地区具有代表性的断裂蚀变岩型金矿,局部还发育有石英脉型金矿床。大—中型金矿床分布于特定的部位,其展布具有等距性,矿体往往赋存在断裂的交叉、复合部位或是构造发生突然转折的部位。通过对焦家金矿田成矿构造的研究,总结出焦家矿区的构造控矿规律、蚀变与成矿的关系,来指导新一轮的地质找矿工作,为寻找新的金矿资源奠定基础。研究表明,断裂是金矿床的主导性控制因素。
Jiaojia gold mine of Jiaodong area is a famous gold concentrated zone.The type of Jiaojia gold mine is mainly altered rock, and the quartz vein-type gold deposits also appear in partial ore district.The formation and distribution of some large and medium gold deposits present the feature of certain part and equidistance.Orebodies usually lie in cross and composite parts of fracture structure or sudden turning parts of structure.Through the study of mineralization structure of Jiaojia gold ore mine,the relationship of ore-controlling function,alteration and mineralization has been concluded.This theory,used as guideline for new geology prospecting,provides basis for discovering new gold resources.Studies have shown that fracture structure is the dominant control factor of gold deposit.
