【摘要】：本研究以中國(guó)西部(主要為揚(yáng)子西緣及鄰區(qū))的燕山期巖漿巖和相關(guān)的金屬礦床為重點(diǎn)研究對(duì)象,重點(diǎn)解決的關(guān)鍵科學(xué)問題為多幕次燕山期巖漿作用形成的深部動(dòng)力學(xué)機(jī)制及其與金屬成礦的關(guān)系,約束中國(guó)西部"燕山運(yùn)動(dòng)"前的構(gòu)造背景,探討特提斯洋的產(chǎn)生、俯沖和閉合過程及其與燕山期多幕式巖漿的時(shí)空演化關(guān)系,構(gòu)建揚(yáng)子地塊西緣及鄰區(qū)中生代洋陸演化格局,揭示中國(guó)西部多幕式"燕山運(yùn)動(dòng)"的基本特征、本質(zhì)及其驅(qū)動(dòng)機(jī)制,探討中國(guó)西部"燕山運(yùn)動(dòng)"與中國(guó)東部燕山期重大地質(zhì)事件之間的關(guān)聯(lián),為揭示"燕山運(yùn)動(dòng)"的驅(qū)動(dòng)機(jī)制提供制約;同時(shí),總結(jié)中國(guó)西部燕山期"安第斯型"金屬成礦的動(dòng)力學(xué)機(jī)制,為找尋中國(guó)的"安第斯型"金屬成礦帶提供重要啟示。
[Abstract]:This study focuses on Yanshanian magmatic rocks and related metal deposits in western China (mainly in the western margin and adjacent areas of Yangtze). The key scientific problems to be solved are the deep dynamic mechanism of magmatism formed in the Yanshanian period and its relationship with metal mineralization, the tectonic background before the Yanshanian movement in western China, and the formation of the Tethys ocean. The process of subduction and closure and its relationship with the space-time evolution of Yanshanian multi-episode magma, the evolution pattern of Mesozoic oceanic land in the western margin of the Yangtze block and its adjacent areas are constructed, and the basic characteristics, essence and driving mechanism of the multi-act Yanshanian movement in western China are revealed. This paper discusses the relationship between the Yanshanian movement in western China and the important geological events of Yanshanian period in eastern China, which provides the restriction for revealing the driving mechanism of the Yanshanian movement, and at the same time, This paper summarizes the dynamic mechanism of the "Andes" metallogenesis in the Yanshanian period in western China, which provides important inspiration for finding the "Andean" metallogenic belt in China.
