摘要
Basic-ultrabasic rocks in Changshagou area of Ruoqiang County, Xinjiang, situated at the joint zone of Altun epicontinental massif and Early Paleozoic Qimantage island-arc belt, extended along Altun major fault, belong to the mafic-ultramafic rock zone. These rocks are composed of peridotite, pyrolite, pyroxenite, gabbro and so on, in which upper part are composed mainly of gabbro (partially, olivine gabbro and pyroxenite) and lower part are composed of pyrolite, peridotite and pyroxenite, which are transferred one another (formed into the cumulus crystal texture). Based on the preliminary field investigation, a mount of Cu and Ni mineralization and magnetite mineralized bodies have been found and then Akeshay nickel ores and Changqing magnetite ores have been delineated. Finally, the author considered that Changshagou basic-ultrabasic complex zone will be of a favoratable potential for Cu, Ni and Fe prospecting.
