Abstract:

In order to solve the great difficulties in exploration with surface covered by the Quaternary and Neogene period at the Wangzulu ore block，three lines （line 188，196 and 204） was laid in the study area for anomaly delineationthrough introducing technology of controllable source audio-frequency magnetotelluric measurements.Combined with field geological survey，we interpreted the findings and roughly determined that the broken zone with gold presented a western trend until the Wangzulu ore block at the Zhaishang gold ore.It has been verified by drilling that No.9 and No.10 mineral vein of the Zhaishangore block almost extended to line 188 of the Wangzulu ore block.Additionally，quartz diorite bin vein was discovered in process of deep prospecting engineering，indicating that the ore-forming materials at the Wangzlu ore block mainly originated from the deep，and that showed the tremendous metallogenic potential.Practice demonstrated that，with the aid of controllable source audio frequency electromagnetic measurement for anomaly delineation，and with verification by deep drilling prospecting model in search of mineralized bodies，remarkable prospecting effect was obtained in the thickly-covered region of the western Qinling.

Key words: Controllable Source Audio-frequency Magnetotelluric Measurements, geological characteristics, ore-search breakthrough, Wangzulu ore block, Zhaishang gold mine, Gansu Province
