The widespread mafic-ultramafic complexes in the Earth are well-known as their hosting Ni-Cu-PGE ore deposits, and their petrogenesis and mineralization have become hot issues in the geological studies. This thesis comprehensively investigated the petrology, mineralogy, geochemistry and geochronology of several mafic-ultramafic complexes in the Beishan Terrane, southern Central Asian Orogenic Belt aimed at systematically determining the mineralization and petrogenetic processes responsible for the formation of the complexes and placing constraints on the tectonic evolution of the Eastern Tianshan and Beishan, and the Early Permian mantle plume. The thesis identified mineralizing indicators of Ni-Cu sulfide deposits and defined the roles of partial melting, fractional crystallization, crustal assimilation and magma injection. The systematical isotopic compositions revealed the mantle source of the mafic-ultramafic complexes had undergone the subduction-related modifications both from the South Tianshan Ocean a
