| 摘 要： | 通过对播卡、新田、小溜口金矿矿化层位的对比研究,认为其矿化层位同属于汤丹群平顶山组。金矿赋矿地层平顶山组为成矿提供了主要物质来源,播卡金矿、新田金矿属于构造蚀变岩型金矿床。认为会东-东川地区平顶山组的找金工作,应以地层、岩浆岩、断裂、蚀变为重要线索。新田矿区及其外围、播卡金矿区控矿剪切破碎带南延地段、小溜口-人民凹-燕子岩地区有继续寻找同类型矿床的潜力。

| Abstract: | The comparative study of the mineralized horizons of the Boka, Xintian and Xiaoliukou gold deposits led us to conclude that the all the mineralized horizons should be assigned to the Pingdingshan Formation in the Tangdan Group. The Pingdingshan Formation as the host horizonsis has provided most ore-forming matter for gold mineralization. The Boka and Xintian gold deposits belong to the tectonically altered gold deposits. Particular attention will be drawn to stratigraphy, magmatic rocks, faults and alteration for future gold prospecting in the Pingdingshan Formation in the Huidong-Dongchuan region. The potential prospect areas comprise the Xintian gold deposit and its surrounding areas, the southern part of ore-controlled shear fractured zone of the Boka gold deposit, and Xiaoliukou-Renmin''ao-Yanziyan areas. |
