摘要：基於目前仍在進行中(第五年)的學術攻頂計畫“Tibet&Beyond”的主要研究成果，本計畫除了將更深入研究西藏-喜馬拉雅和高加索-伊朗-安那托利亞這兩個當今地球上最重要的碰撞造山帶之外，還將針對在中亞造山帶與東南亞地區顯著發生的增生造山作用，展開重點對比研究。主要將利用精緻的年代學和岩石地球化學方法，有系統地彙整歸納相關的岩漿活動紀錄，以期獲得新的觀點與視野，能對整個亞洲的造山演化及地殼生長，乃至大陸板塊構造運動的重大基本議題，提供新的制約和解釋。最終，能夠具體促進台灣在國際地球科學及相關前沿研究領域的能見度和影響力。
Abstract: This project is proposed as the Phase II project based on the success of the still ongoing Phase I project that was set up for conducting a comparative investigation of two active and most important continental collision zones, i.e., the Tibet/Himalaya and the Caucasus/Iran/Anatolia (CIA). I and my team members and international collaborators believe that we have achieved the two principal goals designed for the Phase I project, which are, respectively, to sustain our leading position in the study of Tibetan tectonomagmatic evolution and to create a competitive advantage in the study of the CIA orogeny. One of major research results we have obtained was that the eastern Tethyan “collisional” orogen was preceded in localities by accretionary orogenic processes that, like in the Central Asian Orogenic Belt (CAOB), have produced a substantial amount of juvenile continental crust. Both the Tethyan and Central Asian orogenic belts, therefore, appear to have undergone the “orogenic cycle” that evolved from an accretionary into a collisional system.
As the Phase I project, this newly proposed project will deal largely with key magmatic records in the study area by using a number of modern, “state-of-the-art” geochronological and geochemical tools. This new project, moreover, would investigate not only in the eastern Tethyan orogenic belt, but also in the CAOB and its present-day analogue in South East Asia (SEA), in hope to explore the continental tectonics and orogenesis in entire Asia over space and time. The results are expected to yield critical new constraints, derived particularly from geochemical perspectives, that could help comprehend our understanding of the magma generation, crustal growth, topographic change and major geodynamic processes through which continental orogeny evolves.
