| 摘 要： | 通过对托布卡、小溜口、东川马鞍桥剖面昆阳群地层(包括特征岩性、岩石化学)对比研究,认为托布卡金矿矿化层位相当于东川矿区昆阳群下亚群的平顶山(美党)组和菜园湾(大龙口)组。云南在中元古界的找金工作,应以“黑层”、“断裂”、“蚀变”为重要线索。预测找金工作有望地区有:金矿区控矿剪切破碎带南延地段、小溜口—人民凹—燕子岩地区、因民-下四棵树倒转背斜逆断层带、鸡多向斜东侧茂麓断裂带、东川矿区南侧老鹰岩-白锡腊倒转背斜带。

| Abstract: | Based on the stratigraphic correlation of Kunyang group(includes lithologic featutures,lithochemistry) in Tuobuka,Xiaoliukou. Maanqiao,profile of Dongchuan. It is believed that the mineralized package of Tuobuka gold deposit correspond to the Pingdingshan(Meidang)formation and Caiyuanwan(Dalongkou) formation of lower Kunyang subgroup,Dongchuan mining district. “Black rocks”,“rift”and “alteration” are important indication for gold propecting.The potential gold-search area list below:(1)South extended part of ore-control shearing fracture zone. (2)Xiaoliukou-Renminou-Yanziya area(.3)reversed faults zone of Yinmin-Xiasikeshu overturned anticline.(4)Maolu fracture belt in estern limb of Jiduo syncline.(5) Laoyingyan-Baixila overturned anticlinal belt in southern limb of Dongchuan minging district. |
