| 摘 要： | 通过对塔里木盆地石炭系地面和钻井剖面的研究，总结出４种典型环境下的岩相特征和沉积序列。盆地内不同地区因局部沉积条件（如古水深、陆源碎屑供给量、古气候等）的不同，出现不同的沉积序列。在塔中、塔北一带多出现以碎屑岩为主的沉积序列，而塔西南多出现以碳酸盐为主的沉积序列。尽管各地区喾序列在垂向上的组合方式不同，但各沉积序列特征均能反映出海进一步退的旋回变化。结合生物地层资料，可以识别出４个三级级别（相当于

| Abstract: | Based on the study of the ground surface geology and the drilling data of the Carboniferoous in Tarim basin. It summerized the different sedimentary sequences and litho-facees formed under 4 typical envi- ronments. The different sedimentary sequences were formed in the different region in the basin, due to the different local sediment conditions (such as the depty of water, supply of continental dastic rock source, pale- o-climate). The different sequences reflect the different cycle of regreation or transgreation .Combining with the biographical data, four of third grade cycle of transgreation-regreation. Which indicates that th ere were 4times of sea level change. during Carboniferous in Tarim .Since there was a uplifling occured in the end stage of Carboniferous in local region. There only developed 3 uncomplete regreation-transgreation sedimentary sequences. |
