本研究以中国西部(主要为扬子西缘及邻区)的燕山期岩浆岩和相关的金属矿床为重点研究对象,重点解决的关键科学问题为多幕次燕山期岩浆作用形成的深部动力学机制及其与金属成矿的关系,约束中国西部"燕山运动"前的构造背景,探讨特提斯洋的产生、俯冲和闭合过程及其与燕山期多幕式岩浆的时空演化关系,构建扬子地块西缘及邻区中生代洋陆演化格局,揭示中国西部多幕式"燕山运动"的基本特征、本质及其驱动机制,探讨中国西部"燕山运动"与中国东部燕山期重大地质事件之间的关联,为揭示"燕山运动"的驱动机制提供制约;同时,总结中国西部燕山期"安第斯型"金属成矿的动力学机制,为找寻中国的"安第斯型"金属成矿带提供重要启示。 |

In this project,the important research objects are Yanshanian magmatism and related metal deposits in West China (western Yangtze and nearby areas). The key scientific issue which needs to be resolved is the deep geodynamic mechanism for multi-epoches of Yanshannian magmatisms and its relationship with metal metallogenesis. Some important work needs to be done: Constraining the tectonic setting of"Yanshan Orogenic Movement"in West China; discussing the generation,subduction and closing processes of the Tethys Ocean and their relationships with the spatio-temporal evolution of multi-epoches of Yanshannian magmatisms; reconstructing the configuration of Mesozoic ocean and continent evolution; revealing the basic features and essences and driving mechanism for the multi-epoches of 'Yanshannian Orogenic Movement' of West China; discussing the close relationship between'Yanshannian Orogenic Movement' of West China and Yanshanian great geological events of East China; constraining the driving mechanism for'Yanshannian Orogenic Movement'. In the same time,summarizing the dymanic mechanism for the Yanshannian'Andean-type' metal metallogenesis in West China provides important insights for finding'Andean-type' metal metallogenic belts in China. |
