摘　　要：南秦岭镇旬盆地位于扬子地块北部被动边缘,盆地北以镇安-板岩镇区域性断裂,南界为安康区域性断裂为边界,西至宁陕岩体以东,东至武当古陆。镇旬盆地西缘大致范围为:宁陕岩体以东,旬阳汞锑金矿集区以西所控制的区域。镇旬盆地现已经发现小河、金龙山、惠家沟等多处金矿床,然而盆地西缘地区仅发现了庙沟金矿点、罗家营金矿点及玉泉沟金矿化线索,且规模小、品位低,因此,本文针对该现象,结合地质特征、化探异常等信息,对研究区(镇旬盆地西缘)金含矿性进行探讨。The southern Qinling Mountains Zhen ten ten day basin is located on the passive edge of the north of the Yangtze block, the northern part of the basin is the regional fracture of the Zhen An-Slate Town, the southern boundary is the boundary of the Ankang regional fault, the west to the east of the Ningshan rock mass and the east to Wudang ancient land. The western margin of the Zhen-Xia basin is generally located in the east of the Ningshan rock mass and controlled by the western part of the Xunyang mercury antimony gold deposit area. The small river, Jinlongshan, WELHOME gully and many other gold deposits have been found in the Zhen ten ten day basin. However, the western margin of the basin has only found the miogou gold ore point, the luojiaying gold spot and the gold mineralization clue of Yuquan gully, which is small in scale and low in grade. Therefore, this paper is based on this phenomenon, combined with geological characteristics, geochemical anomalies and other information, to the research area. The gold ore bearing property of the western margin of the Zhen Xia basin is discussed.
