碎裂蚀变岩金矿带上的地球物理场特征分析及应用

ANALYSIS AND APPLICATION FOR CHARACTERISTICS OF GEOPHYSICAL FIELD ON THE GOLD ZONE OF CATACLASTIC ALTERED ROCK

本文介绍了在山东招远北截金矿上进行的磁(△T)及甚低频(VLF)电磁场测量,分析了碎裂蚀变岩金矿带上磁场强度降低和甚低频电磁场强度增大的特征,并以此特征为判据,对金矿外围未知地段的构造作了推断解释,提出了可供钻探验证的有利部位。

This paper introduces the measurements of magnetic method (⊿T) and VLF method on Beijie gold mine in Zhaoyuan, Shandong province, analyses the characteristics on the gold zone of cataclastic altered rock which are reflected in low magnetic field and high VLF electromagnetic field. Taking these characteristics as criteria, the deductive interpretation is made for the structure of unknown region in the periphery of the gold mine and the favourable position for drilling verification is put forward.
