塔里木盆地巴楚地区石炭系高频旋回层序分析

高频旋回层序是海平面高频振荡的结果和产物。通过对塔里木盆地巴楚地区石炭系地面、钻井剖面的详细解析，首次总结出7个高频旋回层序类型，识别出50余个五级（或六级）高频旋回层序，它们在纵向上有规律地组合、叠加，组成8个四级旋回层序，3个三级旋回层序及2个二级旋回层序，构成了塔里木盆地巴楚地区石炭系的层序地层格架，同时也反映了该区石炭纪海平面的变化规律及其沉积响应。

Analysis of the High frequency Cycli csequences of the Carboniferous in the Bachu Area, Tarim Basin

In geological history, sea-level changes anywhere have different period and frequency, which resulting in the formation of sequences with various cyclic orders, and the high frequency cyclic sequences are the result and product of sea level high-frequency fluctuation. Based on the analysis of outrop and well of Carboniferous in the Bachu area, the authors firstly summarized 7 types of high-frequency clyclic sequences and 4 typical patterns as well as 50 fifth (or sixth ) order high-frequency cyclic-sequences. These sequences superimpose each other regularly in the vertical and make up 8 fourth order, 3 third-order and 2 second order cyclicsequences, which form the sequence stratigraphic framework of the Carboniferons in Bachu area, Tarim basin and also reflects the law of sea level changes in the study area and its depositional response.
