城门山铜矿外围深部找矿物探方法研究
The Aapplication of Geophysical Prospecting Methods in the Deep and Peripheral Area of Chengmenshan Copper Deposit
【摘要】 对城门山铜矿矿床地质和岩(矿)石物性进行分析,认为城门山层控硫化物矿体具有低阻、高极化和弱磁异常的特征。在已知矿体上进行的典型剖面EH4电磁测深、高精度磁测和V8复电阻率测量试验,证实了硫化物矿体确实具有上述地球物理特征。按层控矿床的思路,在城门山铜矿外围关注黄龙和五通控矿层位,尝试采用EH4电磁测深和高精度磁测,发现低电阻率、弱磁异常带,然后,利用V8对异常带进行复电阻率剖面测量,对复电阻率视谱参数进行综合解译,最后,选点进行钻孔验证,取得了较好效果。研究表明,城门山铜矿区深部有潜力,外围有远景。
【Abstract】 To Chengmenshan copper mine,analysis on the geology of mineral bed and the physical nature of rock(mineral),think that Chengmenshan stratabound sulfide deposits have the character of low resistivity,high induced polarization and weak magnetic abnormality.Be having already known deposits,we carry on EH4 electromagnetic sounding,high accuracy magnetic measure and complex resistivitie measure of V8 to the typical model section,confirm that the sulphide deposits really have the above-mentioned Earth physical character.The way of thinking that controls a mineral bed by the layer,pay attention to the layer between Huanglong and Wutong in the peripheral area of Chengmenshan copper mine,try the adoption EH4 electromagnetic sounding and high accuracy magnetic measure,and discover low electric resistivity and weak magnetic anomalies,then,making use of a V8 system,go complex resistivity measure to the anomaly brings,and carry on a comprehensive solution to the apparent spectra parameters of complex resistivity,end,choose a point and carry on drilling a hole for verification,obtained better effect.The research expresses that there is potential and prospect in the deep and outer area of Chengmenshan copper mine.
