邵武金坑金矿区构造控矿特征与成因探讨

金坑金矿区是闽北地区有代表性的矿床类型之一。矿区金的富集成矿作用与属于同熔型的燕山早期熊村岩体及其补充体——(石英)闪长玢岩脉关系十分密切。控岩(闪长玢岩脉)控矿构造为刀背顶背斜北西翼层间滑动破碎带,以及在刀背顶背斜核部轴面劈理的基础上利用、改造而发展起来的断裂构造破碎带。

Characteristics of Ore-Controlling Structures and Genesis of the Jinkeng Gold Diggings in Shaowu, Fujian Province

The Jinkeng Gold Diggings is one of representative deposit types in Northern Fujian. The gold enrichment and mineralization in the mine field are in close relationship with early-Yanshanian syntectictype Xiongcun massif and (quartz) diorite-porphyrite veins. The rock-controlling and ore-controlling stuctures in the area are the interlayer-gliding fracture zone in the northwestern limb of Daobeiding anticline, and tectonic fracture zone which develop on the cleavages of the Daobeiding anticline core.
