摘　　要：河北省金厂峪金矿是产于古老绿岩带中的韧性剪切带型金矿床.该剪切带是由多种样式和不同规模的褶皱、面理以及拉伸线理组合而成的复杂构造群体.它们是由早期陡倾的层间剪切和后期宽缓的推覆剪切复合作用的结果.这种作用对脉体、矿体的空间展布和含矿性起了联合控制作用.根据控矿构造研究,结合化探成果,认为本区深部仍有一定远景储量.Gold deposits of this district occur in ductile shearing zones situated in ancient greenstone belt. These zones form a group of complex structures by a combination of folds, foliations and elongation lineations of different types and scales as a result of a composition of early steeply dipping interlayered shearing and late gently dipping nappe shearing. Thus, it plays an important role in controlling the spatial distribuion of ore bodies (veins) and ore potentiality. Based upon a study on ore-controlling structnre and taken geochemical exploration results into consideration, it is believed that this distriet still holds a given amount of prospective reserve at depth.
