摘要:

裂变径迹的热史模拟能再现样品的温度历史,反映盆地因构造、沉积因素所致的沉降-隆升作用过程。江汉盆地周缘宜昌和通山两地侵入岩样品的磷灰石裂变径热史模拟分析结果表明,中生代以来样品经历了冷却速率不同的4个冷却降温阶段,表明江汉盆地周缘印支期后持续的构造隆升。两个快速冷却降温段分别对应于燕山期和晚喜马拉雅期江汉盆地周缘的两次快速隆升。这种过程与印支期以来江汉盆地的构造环境、构造-沉积作用及构造变形相耦合。

Abstract:

Thermal history modeling of fission track can be used to reconstruct time-temperature histories of a sample and reflect subsidence-uplifting process resulted from tectnonic activity and sedimentation in a basin.On the basis of apatite fission track thermal history modeling results of intrusive rock samples from Yichang and Tongshan in the periphery of Jianghan Basin,we think that the samples have come through four stages of cooling with different cooling rates since Mesozoic,indicating the constant uplifting since the Indosinian period in the periphery of Jianghan Basin.Two rapid cooling stages respectively correspond to two quick uplifting in the Yanshan and Late-Himalayan Periods in the periphery of Jianghan Basin.This kind of process is coupled with the tectonic setting,tectonism-sedimentation and tectonic deformation since the Indosinian period in Jianghan Basin.

Key words: fission track, thermal history modeling, uplifting, Cenozoic and Mesozoic, periphery of the Jianghan Basin
