摘要
Based on the previous results about structure, marine volcanic rocks and massive sulfide ore deposits in the Caledonian Orogenic belt in north Qilian Mountains, focusing on the material characters of Precamhrian basement, this study analyzed the source and formation mechanism of metamorphic volcanic rocks in strata of different ages, then suggested some prospects of this region. Finally, based on the continental rift system and in combination with previously regional survey data, the authors proposed that the Xiaolongkou-Jiuge Qingyang section is a potential ore prospecting area, which is associated with massive sulfide deposits related to marine volcanic rocks.
