青藏高原东缘新构造与活动构造研究新进展及展望

    New progress and prospects of neotectonics and active tectonics synthetical study on eastern edge Qinghai-Xizang plateau

    • 摘要: 新构造运动与活动构造对人类的出现、演化、生存和发展都产生着深刻影响。近年来在青藏高原东缘部署开展的活动断裂调查与活动构造体系研究、川滇地块旋扭变形的古地磁学研究、西秦岭地区新构造与活动构造研究、滇西盆谷区的新构造幕划分、腾冲火山活动特征及其新构造背景调查等都取得了一系列重要进展与成果。这些成果对于深入认识和理解青藏高原东部地区现今地壳变形特征及其动力学机制和探索活动构造体系控震作用都具有重要意义,并可为该区的重大工程规划建设与国土规划利用的科学决策和城镇化发展等提供重要的地质依据。

       

      Abstract: Based on the recently completed "the Qinghai-Xizang plateau edge Neotectonics and the Quaternary geological research" project during 2011-2013, a series of important progress and achievements have been achieved in many fields of Neotectonics and active tectonics, and including the active fault survey and active tectonic system research around eastern Tibetan plateau, the paleomagnetism studying on shear-rotation deformation of Sichuan-Yunnan block, the Neotectonic and active tectonic surveying and studying around west Qinling mountain, the studying on Neotectonic movement episodesin typical active grabens and faulted-valley of western Yunnanand the Neotectonic background and activity characteristics of Tengchong volcanic etc. These new geological surveying and studying results are all very important for further understanding present-day crustal deformation characteristics and its dynamic mechanism and to explore the control effect to great significance earthquake eventsof active tectonic system in eastern Qinghai-Xizang plateau. The achievements of Neotectonic and active tectonic fields may also be used as important geological basis for scientific decision on the planning and construction of country major engineering projects and land planning and utilization.
