云南红山—红山牛场铜钼矿区物化探特征及找矿方向

Geophysical-geochemical characteristics and prospecting direction of the Hongshan-Hongshan farm Cu-Mo deposit,Yunnan

通过香格里拉县红山—红山牛场铜钼矿区及外围开展的地质、物化探特征综合研究,对隐伏中酸性斑岩体分布、矿体延伸及深部找矿潜力、矿区外围找矿方向进行分析推断,结果表明:红山隐伏石英二长斑岩—花岗斑岩体主要分布在矿区至欠虽一带,其中红山铜钼矿段多个矿体往南仍有延伸,其深部有较大找矿空间;红山牛场矿段两侧有矿(化)体分布,其西侧Pb、Zn、Cu化探异常高值区有较好的找热液型铅锌多金属矿前景,是今后地质工作的重要地段。文章总结出在香格里拉地区采用重力+化探+磁电+钻探等组合方法寻找斑岩—矽卡岩型矿床是行之有效的。

This paper tentatively discusses the distribution of concealed intermediate-acid porphyry,the extension of the ore body,the prospecting potential in the depth and the prospecting direction of the propery periphery by comprehensively analyzing the geological and geophysical-geochemical characteristics of the Hongshan-Hongshan farm Cu-Mo property and its periphery in Shangri-la,and deduces that Hongshan concealed quartz monzonite porphyry-granitic porphyry mainly distribute in the area of from the property to Qiansui area,multiple ore bodies in Hongshan Cu-Mo ore block are still extending to the south,of which the deep prospecting potential is great,too. Ore（ mineralized） bodies are developed in both sides of Hongshan farm ore block,and the Pb,Zn,Cu high-value anomaly are aoccurred in the west side has great potential for prospecting hydrothermal Pb-Zn polymetallic deposit,and is the important target area for future geological prospecting work. The combined gravity ＋ geochemical ＋ magnetic-electrical ＋ drilling exploration techniques are effective on prospecting porphyry-skarn-type deposit in Shangri-la area.
