Abstract: The Buheta Cu (Au) mineralization district is located to the west of the north margin of Nalati tectonic belt, Zhaosu County in Xinjiang Province. Monzogranite and quartz diorite are developed in this deposit,and the Cu-Au mineralization is found in the margin of the plutons and the contact zone between the plutons and wall rocks. The LA-ICP-MS zircon U-Pb dating results of monzogranite and quartz diorite are (434.5±4.6) Ma and (445.7±5.1) Ma, consistent with Late Ordovician to Early Silurian. According to the geochemical data, they belong to shoshonitic granites of peraluminous S-type with high A/CNK value of 1.35-1.42 and 1.47-1.71 respectively. The granites exhibit weak negative Eu anomalies(δEu=0.67-0.80), enrichment in LREE and large-ion lithophile elements (such as Ba、Th and U),and depletion of high strength elements(such as Nb and Ta). It suggests that the granites were generated from the partial melting of metagreywacke. Combined with the regional tectonic evolution, we conclude that the emplacement of granites in Buheta mineralization district was related to the post collision stage of the Middle Tianshan plate and the Yili plate through a partial melting of middle and lower crustal sedimentary rocks.

Key words: Buheta mineralization district, zircon U-Pb age, S-type granite, Late Paleozoic, geochemistry
