摘要
笔者以安妥岭铜钼矿区为实例,重点介绍连续电导率成像技术(即EH4)在斑岩型多金属盲矿体勘查中的应用和效果。在结合以往地质、物探成果的基础上,根据EH4资料推测出了与侵入岩关系密切的F1、F3构造断裂带的位置、走向、倾向;探明了具有控矿作用的黑云母花岗闪长斑岩体的位置、埋深、形态等。根据EH4资料并结合当地地质条件确定钻孔位置,钻孔见工业矿体20多层,矿体总厚度达110 m,并且在350 m以下见到黑云母花岗闪长斑岩体。
Taking EH4 data of Antuoling copper-molybdenum deposits as an example, this paper deals with the application and effectiveness of Continuous Conductivity Imaging Technology in expl deposits. Combined with previous geological and geophysical information, EH4 molybdenum deposits is used for informing the location, strike and dip of F1 and F3 orating porphyry-type insidious result of Antuoling copperfault zones closely related with biotite granodiorite porphyries, and the location, depth and shape of the biotite granodiorite porphyries leading to the formation of ore bodies. According to these information, the drilling locations are determined. More than 20 layered ores were found in the drilling. The total thickness of the ore bodies reach one handred and ten metres. And the biotite granodiorite porphyry was found in the drilling even below 350 meters, which means ther is a good potential in this ore field.
