摘要
熊耳山地区金矿构造挖矿系统表现为：伸展裂陷盆岭构造环境为金矿成矿提供背景条件（物质场、能量场、空间场）；南部马超营断裂及北部不整合面间拆离带控制南北两大金矿成矿带；相关次级断裂构造及北东向断裂构造叠加部位为金矿成矿提供容矿空间；东部与古火山机构有关的张裂构造控矿。拆离带及火山机构控矿的提出，丰富了本区构造挖矿型式，拓展了找矿视野，对认识成矿规律和找矿预测具有重要意义。
The ore-controlld structUra systems of gold dpeits in Xionger mountain areaare as follows: ridge-basin structural environmnt related extensiona down-faulted basin providedthe bahaound conditha (i. e. material field, energy field, sPace field); southern Mahaoyingfracture are and northern unconformty interface conrolled the spatial distributbo of twomineralized sones in this area, the subsidiary faults related Machaoying fracture are and theintersectdri parts between Machaoying fracture zon, Unconformity inteffoce and NE faultsprovided the space for the god deopits; and in the eastem Xionger mountain area, however, theextensional fractures related ancient volcanic apparatuese were closely related to goldmnerlization. The result of this article shows that detached zone and volcanic apparauscontroled the gold deopits suggest som new ore-conrolled structural pattems in this region andwiden the scopes for gold-prospecting and abo have an irnpetant sighficane for the recogntionof ndneraliZatbo law and for the oreprospecting and prognosis of gold deposits.
