英文摘要Subduction initiation is an essential process in magmatic and tectonic evolution of the Earth and plays an important role in plate tectonics. During subduction initiation, four main geological units are formed, namely; magmatic episodes with various geochemical characteristics, supra-subduction zone (SSZ) ophiolites, metamorphic soles and boninitic magmatism with associated chromitite deposits. The Tethyan orogenic belt has been attracting a great deal of attention for a long time as it preserves an excellent record of plate tectonic processes. The southern Turkey occupies part of this belt, and preserves well-defined SSZ ophiolites and associated metamorphic soles, which are considered as the remnants of the Neo-Tethyan oceanic plate between the Eurasian and Arabian continental plates. These geological records of subduction initiation in southern Turkey are summarized as following : 1) mantle-derived magmatic rocks are widely developed and show large compositional variations from MORB-like, through transitional to boninitic; 2) most ophiolites and their associated metamorphic soles are well preserved and contain complex mafic dykes systems, indicating multiple episodes of magmatic activities; 3) the metamorphic soles commonly underlie the ophiolites and their metamorphic histories are coeval to the formation of the ophiolites; 4) numerous chromitite deposits occur in the mantle and crustal sequences of the ophiolites and span a wide range of compositions from high-Cr, intermediate to high-Al types, most likely in response to various magmatic events. Thus, these well-characterized geological massifs record the entire formation to subduction process of the Neo-Tethyan ocean.
