东秦岭北锑-汞矿带沿区域性深大断裂及其旁侧断裂分布，自西向东主要有高岭沟、蔡凹、掌耳沟、大河沟等锑矿床，但研究程度不高。本文重点阐述了锑-汞矿带区域成矿特征，讨论了韧性剪切带与锑矿成矿的关系。锑矿体产状一般呈团块状、透镜状、脉状、网脉状和扁豆状，金属矿物主要为辉锑矿，其次有锑华和黄铁矿，围岩蚀变发育有硅化、高岭土化、碳酸盐化、粘土化、重晶石化和黄铁矿化等。构造控矿作用可分为三级：一级为朱阳关-夏馆大断裂，控制矿带的产出；二级为大断裂的压扭性分枝断裂，为主要容矿构造；三级断裂发育在二级断裂之间，由扭力和引张作用形成规模不大的裂隙，或使原有的层问裂隙扩大形成储矿构造。矿区发育具有显著糜棱面理的长英质糜棱岩，锑矿化的石英脉就产于糜棱岩之闻，局部沿糜棱面理贯入糜棱岩中，锑矿成矿作用明显受区域韧性剪切带控制。 |

The northern of antimony mineral belt in East Qinling distributed to follow the regional great faults and the side part, mainly having Sb deposits, such as Gaolinggou, Caiwa, Zhangergou and Dahegoukou etc. from the west to east. This text expatiates Sb deposits characteristic, according to wild and laboratory studies with the mi- nute structure, discusses the relation of tenacity shear zone and the Sb deposits. The ore body produces appearance to present the conglomeration form, anastigmatic form, vein form,the net vein form and the hyacinth bean form gen- erally. The metals mineral is mainly the antimonite, with valentinite,pyrite secondly. There is widespread silicification, kaolineization, carbonateization, clay, bariteization and the pyriteization etc, and mainly hosted in the tectonite rock. Structures of controling the mineralization is divided into three class, one for Zhuyangguan-Xiaguan fault is composed of trunk ductile shear belt, controling mineral zone to produce, secondary class is for press and twist structure of the offset ductile shear belt, mainly for holding ore body structure, third class structure is based upon second class gtructure, from wring and tensile force, forming the small cranny, or making the original layer cranny enlargement for store ore body structure. The mineral area developed the feldspar quartzmylonite which show the mylonitic foliation, the quartz vein of containing antimony mineral endow with the mylonite, the metallogenic function is clearly limited by the regional ductile shear belt. |
