阿尔泰山南缘白垩纪以来的剥露历史和古地形恢复OA北大核心CSCDCSTPCD
Denudation and exposure history and paleotopographic reconstruction of the southern margin of the Altay Mountains since Cretaceous
应用裂变径迹技术研究阿尔泰山南缘中新生代以来的隆升剥露历史,并对古地形进行恢复.对所获得的11个磷灰石样品的裂变径迹年龄分析表明,裂变径迹年龄变化分布于99.1～43.7 Ma之间.该地区晚白垩世以来平均视剥露速率为0.050 mm/a.热史模拟结果表明,阿尔泰山南缘自白垩纪以来经历了多期冷却剥露历史:早白垩世至晚白垩世晚期(约120～75 Ma),剥露速率为0.044 mm/a;晚白垩世晚期至始新世(约75-70～50 Ma),剥露速率为0.0…查看全部>>
Altay is an important part of the Central Asian Orogenic Belt, and also the largest accretion orogen in the world. At present, scholars both in China and abroad are focusing their Altay studies on the evolution of various stages of orogenic movements as well as geochemical and geochronological time constraints on the orogenic activities. In contrast, the study of the Mesozoic-Cenozoic cooling history is relatively insufficient. To carry out the researches on…查看全部>>
