目前我們正进行勘探工作的是一个比較典型的低溫热液銻矿床,它賦存在中上泥盆紀的灰頁岩层中,在灰岩受到矽化的部份产出矿体。从开采与勘探资料证实,几乎所有矿体都是产出在背斜褶皺的軸部及傾沒处,一般是沿层間裂隙、空洞充填,呈扁豆状,脉状。上复的长龙界頁岩起了遮挡的作用,使其下部矿化富集;而矿液之通路是由分布在西部延伸达十多公里的二級断裂构造所构成。这就十分有必要用构造等高线图来分析成矿有利的地質构造,以有效地指导整个勘探工作。我們根据苏联专家的多次建議,编制了一些
At present, we are carrying out exploration work is a typical low-temperature hydrothermal antimony deposit, which is present in the Upper Devonian shale formation, in the limestone silicified part of the ore body. Mining and exploration data confirm that almost all ore bodies are produced at the shaft and declination of anticlinal folds, usually along intergranular fractures, empty filling, lenticular, veins. The complex Longchangjie shale plays a blocking role, enriching the lower part of the mineralization, and the fluid path is composed of secondary fault structures extending over 10 kilometers in the west. This makes it very necessary to use structural contour maps to analyze favorable geologic formations in ore-forming so as to effectively guide the entire exploration work. We compiled some on the basis of many suggestions by Soviet experts
