The Gangdise volcanic magmatic arc is an important copper-polymetallic prospective area. The deposits are closely related to intermediate-acid igneous rocks. It is important to evaluate aeromagnetic anomalies caused by igneous rocks. This paper studies the aeromagnetic features of two typical porphyry deposits in South Gangdise (Jiama and Qulong) by three-dimensional inversion of magnetic data. Combined with previous achievements, this paper concludes that the upright rock and back magnetization constitutes the principal feature of these two deposits. On such a basis, in combination with the distributional regularity of porphyry copper deposits in South Gangdise, this paper predicts porphyry copper deposits of this type by Hough transform., and delineates 18 potential prospecting areas, thus providing important information for mineral exploration.
