英文摘要The mafic-ultramafic complex in the Xiangshan area of the eastern Tianshan Mts., Xinjiang, produce a medium-sized Middle-Xiangshan Cu-Ni deposit and a large-scale western-Xiangshan Cu-Ni-(V-) Ti-Fe deposit. Through systematical field investigation and sampling for the suit of mafic-ultramafic rocks, a detailed petrology and geochemistry research was carried out and two rock series with different metallogenetic specialization in study area have been identified. 1) Early stage rock series related to (V) -Ti-Fe mineralization with rock association of aplitic gabbro, Ti-Fe gabbro (Ti-Fe ore), Ti-bearing (homblende) gabbro and leucogabbro, shortly called as "(V-) Ti-Fe rock series". The three rock types of Ti-Fe ore, Ti-bearing gabbro and leucogabbro have continued evolution and gradual transition in mineral assemblage and rock texture. This series is characterized by alkali, Fe, Ti, Si, Al and Ca-rich, high calc-alkaline enrichment index (calk/in) and low mafic index (m/f) in chemical composition, and by distinct plagioclase cumulation and magma fractional crystallization in geochemistry of REE and trace elements. 2) Later stage rock series that can intrude in the Ti-Fe series rocks related to Cu-Ni sulfide mineralization with rock association of ultramafic rocks, rhythmic olive gabbro and altered hornblende gabbro, shortly called as "Cu-Ni rock series". This series is characterized by Mg-rich and relatively lower Fe, Ti, Si, Al, K and Na contents in chemical composition, and by gently REE and trace patterns that reflect a characteristics of primary mantle or depleted mantle. fire other hypabyssal dykes (diabase) in the ore district, mainly as later additional facies of gabbro, display an end evolution of the two rock series, i.e., product of magma mixing of two residual magma series.
