哈萨克斯坦楚-萨雷苏盆地热兹卡兹甘地区构造运动与沉积演化

本文基于对楚-萨雷苏盆地热兹卡兹甘地区的构造运动、相应动力学机制、沉积地层的研究,对楚-萨雷苏盆地盆地上古生界沉积演化做了阐述,提出了热兹卡兹甘地区晚古生代经历了早中泥盆世火山盆地—晚泥盆世(成盆初期)滨海冲积平原、局限台地—早石炭世(海侵期)台地、台缘斜坡、陆棚—中晚石炭世(海退期)海陆交互相三角洲—早二叠世(干旱气候期)干盐湖—晚二叠世盐湖的沉积演化。

Tectonic movement and sedimentary evolution in the Zhezkazgan region, Chu-Saleisu Basin, Kazakstan

The Upper Palaeozoic sedimentary evolution is explained on the basis of the tectonic movements,dynamic mechanisms and sedimentary strata in the Zhezkazgan region,Saleisu Basin,Kazakstan.The authors in this paper suggest that the Zhezkazgan region went through the following stages of sedimentary evolution throughout the Late Palaeozoic: the volcanic basin during the Early and Middle Devonian(the early stage of basin initiation),the littoral alluvial plain and restricted platform during the Late Devonian,the stage of platform with platform-margin slope and shelf during the Early Carboniferous(transgression period),the marine mixed with continental delta during the Middle and Late Carboniferous(regression period),the playa during the Early Permian(dry climatic period),and finally the salt lake during the Late Permian.
