摘要: 5个磷灰石样和4个锆石样的裂变径迹测年证据以及热历史的定量模拟研究表明,博格达山自晚侏罗世末-早白垩世开始隆升,总体表现为持续的隆升过程,具有4个主要期次的演化阶段,起始时间分别为150~106、75~65、44~24、13~9 Ma。其中44~24 Ma之前,博格达山南、北缘隆升速率近于一致。之后,博格达山的隆升转为区段性,南、北缘形成差异隆升。北缘在42~11 Ma为近于稳定的状态,隆升速率为1 m/Ma,11 Ma至今隆升速率为190.6 m/Ma;而南缘在26~9 Ma间隆升较快,速率为41.2 m/Ma,9 Ma至今隆升速率为162.9 m/Ma。这种差异性的隆升可能一方面与印度板块和欧亚板块碰撞的远程效应有关,另一方面也是更主要的原因可能受博格达山不同段深部差异性动力学过程所控制。Abstract: Fission-track dating evidences from 5 apatite samples and 4 zircon samples and modeled time-temperature thermal history indicate that the uplift process of Bogeda Mountain since late Jurassic-Cretaceous can be divided into four stages:150~106,75~65,44~24 and 13~9 MaBP.Before 44~24 Ma,the cooling rate and uplifting rate of the southern and northern segments of Bogeda Mountain were the same,but since 44~24 MaBP,the uplifting of the southern and northern segments of Bogeda Mountain has become different.During 42~11 Ma,the northern segment was in a steady stage,with the cooling rate being 0.03℃/Ma and uplifting rate 1 m/Ma.During 11 Ma-present,the northern segment was in a rapidly cooling and uplifting stage,with the cooling rate being 5.72℃/Ma and uplifting rate 190.6 m/Ma.The southern segment was in a rapidly cooling and uplifting stage since 26 Ma,with the cooling rate being 1.24℃/Ma and uplifting rate 41.2 m/Ma during 26~9 Ma and 4.88℃/Ma and 162.9 m/Ma during 9 Ma-present.The difference in the uplifting may be because of collision between the Indian and Eurasian plates and also of being controlled by the processes of dynamics at different depths of Bogeda Mountain.
