Main Metallogenic Characteristics in the Beishan Orogen

The Beishan orogen located along the northern margin of the Talinu massif belongs to thewestern-centralportion of the Tianshan-Xing'an orogen of the Paleo-Asia tectonic domain.The crustal components in the region include: late Archean crystallization basement, middle-late Proterowic fold series and Paleozoic cover of upper Simian to Permian stratigraphic system.Structure is characterized by fault blocks are divided by a series of arc-foam faults in a east-west stretch.In side he blocks, there are intensive folds and active magmatign.Granites can be classified to I-and S-type, andmafic and ultramafic rocks are Ferich and Mg-rich kinds.Volcanicspossess continental rift feature.A number of ophiolite canes have been found in the area.All these indicate an excellentmetallogenic setting.Seven types of ore deposit have been reposted in the area:①interm ediate-acid intrusion-related hydro thermal ore deposit;②volcanic hydrothermal ore deposit; ③meta-sedimentary ore deposit;④sedimentary ore deposit;⑤exhalative sedimentary reworked deposit;⑥basic-and ultrabasic magma-related ore deposit;⑦hydrothermal reworked ore deposit.Tentarget prospecting areas have been pinpointed according to detailed geological work.
