摘　　要：在东昆仑中西段布喀达坂峰地区发现了一套含早—中泥盆世生物化石的海陆交互相地层,从而确定了该地区泥盆纪地层的存在。该套地层可与东昆仑西段泥盆纪布拉克巴什组相对比。就目前研究状态而言,确定了早中泥盆世地层在东昆仑西段地区由西往东延伸的位置。同时,该套地层的发现及其古构造沉积背景的确定对东昆仑造山带的研究具有重要意义。A sequence of paralic strata which contains biota fossils from Early-Middle Devonian is found in Bukadaban district in west-middle section of East Kunlun Mt. and it is certained there is the strata of Devonian period. The sequence of the strata may be correlated with the Devonian period Bulakebashi Formation in west section of East Kunlun. By the researching currently, the range of the Early-Middle Devonian strata ranging from west to east in west-middle section of East Kunlun Mt.is certained. Meanwhile, discovery and its tectono-paleogeography background of the strata has a great significance for the study of orogenic belt of East Kunlun Mt.
