【Abstract】 This area is abundant in mineral resources, including copper, lead zinc, gold, iron, mercury and nickel. The favorable host strata may be the Paleozoic and Mesozoic marine volcanic rocks in this area, in which the Mesozoic sedimentary strata, especially the Triassic system, can be available strata for ore prospecting. The genesis of copper and nickel deposits is related to the intrusive rocks. The mineralized zones are evidently controlled by regional deep and major faults at northwest, northwest west, northwest to south north directions. The deposits relevant to intermediate acid intrusive rocks were commonly presented by local gravity anomaly at lower in round and elliptical shapes. The deposits common occur in the center and/or marginal places with minus anomaly and the aeromagnetic anomaly appears to be abnormal reflection with a general breadth value under 50nT. Other deposits relevant to ultrabasic basic intrusive rocks, with which the local gravity anomaly with elliptical shape presents in a positive anomaly, often occur in the margin of the positive anomaly and correspond to a positive magnetic anomaly.更多还原
