盆地古地温研究是盆地热演化研究的关键.盆地形成越早,演化史越复杂,则现今地温与古地温相差越大.沉积盆地的古地温研究是一个复杂的地质问题,必须依据大量实际资料的综合分析和不同方法相互相比、相互验证才能较真实地恢复沉积盆地的古地温场状况及热历史.1 盆地构造演化吐鲁番-哈密盆地(简称吐-哈盆地)经历了3个主要构造演化阶段):石炭纪～早三叠世陆内裂谷作用阶段(早石炭世～晚二叠世早期的裂谷一拗陷-萎缩期、晚二叠世晚期～早三叠世的前陆期)、中晚三叠世～早第三纪广盆形成阶段(中晚三叠世稳定～拗陷期、侏罗纪断陷-拗陷-挤压期、白垩纪萎缩期和早第三纪拗陷期)和晚第三纪～第四纪挤压型山间盆地形成阶段.三叠纪～早第三纪成为稳定的拗陷型盆地,盆地性质类似于克拉通,以盆地的整体沉降、连续沉积、断裂发育、地层展市复杂、缺乏褶皱和角度不整合为特征.
The study of paleo-geothermal temperature in the basin is the key to study the thermal evolution of the basin.The earlier the basin was formed and the more complicated the evolutionary history, the greater the difference between the geothermal temperature and the paleo-geothermal temperature.The study of paleo-geothermal in the sedimentary basin is a complex geological problem, The comprehensive analysis and the comparison of different methods with each other, mutual verification can more accurately restore the sedimentary basin paleo-temperature field conditions and thermal history.1 Basin tectonic evolution The Turpan-Hami basin (Tuoha-Hase basin) experienced three major tectonic evolution Stage): during the Late Carboniferous-Early Triassic intracontinental rift stage (Early Carboniferous-Early Late Permian rift-depression-atrophy, Late Late Permian-Early Triassic ), Middle-late Triassic to early Tertiary broad basin formation stage (middle-late Triassic stable ~ depression, Jurassic rift - depression - crustal depression, Cretaceous atrophy and Early Tertiary Depression period) and the Late Triassic to Quaternary extrusion-type inter-basin basin.The Triassic to Early Tertiary became a stable depression basin, which is similar in nature to craton, with the whole settlement of the basin , Continuous deposition, fracture development, stratum show complex , Lack of folds and angular unconformities.
