摘要
笔者通过对研究区岩心的详细观察和岩石薄片样品分析,根据岩石特征、测井标志、地震特征,将塔河地区塔塔埃尔塔格组分为两个岩性段,为滨海(有障壁)沉积体系。下段为高潮坪(泥坪)和中潮坪(混合坪),上段为低潮坪(砂坪)。塔河地区有障壁滨海的障壁为塔北(沙雅)古隆起高部位,广海为南天山洋。物源主要来自东北缘的库鲁克塔格及南缘的阿尔金山。
The Silurian Tata＇airtage Formation in the Tarim River area, Xinjiang may be divided, on the basis of cores, well logs and seismic data, into two lithologic members belonging to the offshore （barrier） depositional systems. The lower member is composed of the high tide flat （ mud flat） and middle tide flat （ mixed flat）, while the upper member consists of the low tide flat （sand flat）. The offshore （barrier） in the Tarim River area is the Tabei （Xayar） palaeouplift, and the open sea is the South Tianshan Ocean. The provenances include Kuluketage in the northeastern part and Altun Mountains in the southern part.
