砾岩型金矿是金矿床类型中一种重要的类型。不同类型金矿床对应于不同的金赋存状态,为从自然重砂金矿物异常角度寻找金矿床提供了可能。总结了鲁东地区自然重砂金矿物异常分布规律,结果表明该区金矿物异常具有呈群、带分布的特点,大多数金矿物异常均与地层、侵入岩及金矿床(点)关系密切。对胶州市孝源店子地区的自然重砂金矿物异常进行查证发现,该异常的产生与杜村组砾岩中含金有关,指示胶莱盆地东南部可能存在砾岩型金矿。莱阳群砾岩层是胶莱盆地砾岩型金矿的找矿方向。 Conglomerate-type gold deposits are an important type of gold deposit. Different types of gold deposits correspond to different gold occurrences, which makes it possible to search for gold deposits from the perspective of natural gravity gold and gold anomalies. The results show that the anomalies of gold minerals in this area are characterized by cluster and belt distribution. Most of the gold mineral anomalies are closely related to the strata, intrusive rocks and gold deposits (spots). The verification of the anomalous natural gold and sand minerals in the Xiaoyuandianzi area in Jiaozhou found that the anomalous occurrence was related to the gold content in the conglomerate of the Ducun Formation, indicating the possible presence of conglomerate-type gold deposits in the southeast of the Jiaolai Basin. Laiyang conglomerate is the prospecting direction of conglomerate type gold deposit in Jiaolai basin.
