摘　　要：红十井金矿,产于中、上石炭统基性火山岩和火山碎屑岩中,为受断裂带控制的韧性剪切带型金矿床。原认为主矿体南倾,未查明侧伏方向,在矿体南侧和中、东段布钻,深部未打到矿体,仅求得0.947 t金储量。笔者等经地质构造、矿体空间展布形式、矿物热电性和电磁场测深等研究,预测主矿体北倾,西延,南西西侧伏,北东东仰起,在主矿体北侧和中、西段布钻,结果在深部和中、西段均打到了矿体,金储量由0.947 t增加到10.1t以上,取得了突破性进展。The Hongshijing gold ore deposit, which occurs in volcanic rocks and pyroclastic rocks of the Middle and Late Carboniferous, is of the brittle-ductile shear zone type controlled by a rift belt. The main orebody was o-riginally considered to dip south, so drill holes over the south, middle and east parts of the orebody did not find the orebody. Therefore, only 0. 947 tons of gold reserves were obtained. Based on studies of geologic structure, spatial distribution of orebody, thermal and electric properties of minerals and electromagnetic sounding, the authors predicted that the main orebody is arcuate in shape, extends westwards and dips northwards on the whole. Its WSW part plunges while the NEE part rises. As a results, drill holes over the northern, central and western segments of the main orebody have encountered the orebody, yielding gold reserves of over 10 tons.
