| 摘 要： | M盆地位于塔拉斯—费尔干纳(卡拉套)大型走滑断裂最北端,构造特征表明其具有复杂的形成演化过程。笔者从控盆断裂的发育历史出发,分析了盆地发育的构造背景,厘定了盆地类型,进一步研究了盆地演化特征。研究结果表明,控盆断裂受板块构造运动影响,存在早期左行走滑和后期右行走滑;M盆地为早中侏罗世的走滑-拉分盆地,属于走滑-伸展叠瓦扇构造系统。盆地中新生代地质演化大体经历了初始张裂(晚三叠世)、断陷发育(早中侏罗世)、断坳转换(晚侏罗世)、坳陷发育(白垩纪)和萎缩隆起(古近纪)等5个阶段,其中早中侏罗世为盆地断陷伸展、沉积与沉降的主要时期,白垩纪主要为坳陷期。

| Abstract: | The M Basin is located in the northernmost part of Talas-Fergana(Karatau) large strike-slip fault,and its tectonic features show that the basin has experienced complicated formation and evolution process.The authors analyzed the geotectonic background of M Basin based on the growing basin-controlling history of the fault,identified the basin style and studied the evolution features of the basin.The results show that,under the influence of plate motion,the basin-controlling fault experienced left-lateral str... |
