摘要
As an important copper-molybdenum deposit in the East Qinling copper-molybdenum belt,no major breakthrough has been made yet for ore prospecting in the Qiushuwan mine and its surrounding area.It is thus critical to determine the shape and position of the Qiushuwan rock body for expanding exploration.Through analysis of the ore-forming source rocks,alteration and mineralization zoning,in combination with remote sensing and geophysical techniques,this work suggested a mineralization alteration model for the study area.Then drill holes were deployed to validate the model,and preliminary success in prospecting has been made in the Qiushuwan deposit.This paper shows that the Qiushuwan porphyry is the ore-forming source rock in this region,there are still granitic porphyries below the depth of 1000 m.Thus the deep-seated porphyries should be the future prospecting targets.The nearly NE-trending faults serve as conduits for magma migration from the east to the northwest,and the burial rock bodies are shallow in the west and deep in the east.
