摘要: 栾川鱼库钼矿床位于华北克拉通南缘,矿床的形成与燕山期岩浆-矽卡岩热液成矿作用有关,是近年来发现的大型隐伏钼多金属矿床。对鱼库矿区骨干剖面的深部钻孔(>1 000 m)中黄铁矿开展热电性标型特征分析,发现样品中黄铁矿以N型为主,总含量达96%。根据黄铁矿导型及热电性参数变化特征推测出矿体向深部有一定规模的延伸。根据热电性实验数据计算出成矿温度范围在270~332 ℃之间,结合矿床矿石特征判断该矿床属于浅成中温热液成矿。并利用地质统计学知识,运用ArcGIS对计算出来的成矿温度进行克里格插值分析,探讨矿区深部成矿规律。

Abstract: Luanchuan Yuku molybdenum deposit is located in the southern margin of the North China Craton, whose Yanshanian magmaskarn type mineralization is related to the large concealed Mo polymetallic deposit discovered in recent years. The samples from deep drilling mining (>1,000 m) were used to analyze thermoelectric characteristics of pyrite and the aim was to provide an important scientific basis for the exploration of deep prospecting in this area. The research contents and methods are as followed:the thermoelectric properties of pyrites are mainly of the N type with a total content of 96%.The thermoelectric parameters characteristics reflect the orebody denudation to the middle and lower position, but the statistical data shows the depth potential extension. According to the pyroelectricity of pyrite ore in the study area to calculate the forming temperature of fan between 270-332 ℃, the deposit belongs to shallow medium temperature hydrothermal mineralization. On the basis of geological statistics, ArcGIS Geostatistical Analyst modular was used to analyze the trend of metallogenic temperature, and the oreforming regularity and potential targets were discussed.
