| 摘 要： | 中国北方主要天然气盆地包括地洼型华北盆地、柴达木盆地、塔里木盆地和残留地台型鄂尔多斯盆地。华北盆地构造热演化史可以划分为四个阶段，鄂尔多斯盆地构造热演化史包括两个阶段四个发展期，柴达木盆地构造热演化过程分五个阶段，塔里木盆地则经历了四个阶段的构造热演化历程。中国北方主要天然气盆地的构造热演化具有如下共同特点：多阶段性，多旋回性，地热场结构多层性和地热场展布与构造分区一致性。自太古代至今，中国北方主要天然气盆地构造热演化的总体规律是：高（温）热（场）前地槽穹隆阶段→高热地槽阶段→低热地台阶段→高热地洼阶段。地幔热场、地幔蠕动流和地壳厚度是决定大陆地壳构造热演比性质的三大主体因素。

TECTONOTHERMAL EVOLUTION OF MAIN NATURAL GAS-BEARING BASINS IN NORTHERN CHINA |
| |
| Abstract: | The main natural gas-bearing basins in northern China are Huabei Basin,Ordos Basin,Qaidam Basin and Tarim Basin. Four tectonothermal evolution stages can be recognised in Huabei Basin,two stages including four periods inOrdos Basin, five stages in Qaidam Basin and four stages in Tarim Basin. The main natural gas-bearing basins in northern China are common in multiple stages and multiple cycles of tectonothermal evolution,in multiple tectonothermal layers,and in that the distribution of geothermal field is correspondent to the tectonic divisions.Since Archaean,there has been a complicated tectonothermal process in northern China,ie.the highly geothermal geodome stage→highly geothermal geosyncline stage→lowly geothermal platform stage→highly geothermal depression stage The geothermal field in the mantle ,mantle creep current and the thickness of the crust are three main factors controlling the tectonothermal evolution of the continental crust . |
