摘要
英吉沙南阿克巴西麻扎尔一带的中泥盆统克孜勒陶组,下未见底,与上覆上泥盆统考库亚组之间呈整合接触.从剖面特征分析,自下而上可划分出海岸相及混积陆棚相(包括生物礁、风暴岩),为一典型的进积沉积体系,各相段中沉积特征明显,沉积构造十分发育,特别是上部具有点礁性质的生物礁不仅礁核、礁翼清晰,而且定殖、拓殖、泛殖、统殖等4阶段特征明显,该剖面为研究滨浅海相沉积的良好剖面。
The lower end of the middle-Devonian Keziletao fonnation in Akebaximazhaer region of Southern Yingjisha didn't crop out and the upper-Devonian was conformable contacted u(?)on the the middle-Devonian. Based on the analysis to section characteristics, a typical progradation sedimentary system from seashore facies to melange shelf facies(including bioherm and tempestite) was recognized. The sedimentary characteristics of every facies is distinct and the sedimentary structure is well developed. In the upper section, bioherm is of dot reef features and the reef core and reef flank were well preserved. Four stages characteristics including stationary multiply, ex(?)ensive multiply, wide multiply and uniform multiply are clearly observed. This section is good for researching shallow sea facies sediment.
