摘要
脉状金矿区的大地构造位置，多处在地台（或陆台）边缘的隆起带（或褶皱带）上，区内有前寒武纪地层的出露，紧邻深大断裂，且断裂构造十分发育，多具中生代岩浆活动等。对蓬莱地区脉状金矿床，总结了挖矿特征及控矿规律。
Tile geotectonic location of most of vein gold deposits lie in the fold zone ofthe platform edge, in which occur the Precambrian strata,and it adjoins deep-fracture zone,in this area faulted structure is activity,and it had ever occurred the Mesozoic era magmaticactivity. To the vein gold deposit of Penglai regions,authors sum up the features of ore control structure and the ore-control regularity.
