详细描述了羌塘盆地北部乌兰乌拉湖地区马料山侏罗系剖面,将剖面划分为雀莫错组、布曲组和夏里组3个岩石地层单位,其中布曲组出露齐全,化石丰富。根据沉积环境及相对海平面变化规律将布曲组划分为2个沉积层序,并讨论了各体系域特征。依据马料山剖面布曲组的生物组合及分布特征建立了1个双壳类生物组合带即Chlamystipperi-Protocardiastricklandi组合带,并细分为3个组合亚带,其时限为中侏罗世巴通期。
A detailed description of the Jurassic section of the Ma’er Mountains in the Wulanhula Lake area in the northern Qiangtang Basin divides the sections into three lithostratigraphic units of the Qiaomuluo Formation, the Buqu Formation and the Xiali Formation, in which the Buqu Formation is fully exposed, Fossil rich. Based on the sedimentary environment and relative sea level variation, the Buqu Formation is divided into two sedimentary sequences, and the characteristics of each system tract are discussed. According to the bio-assemblage and distribution characteristics of Buqu Formation in the section of the Ma-sha mountain, one bivalve bio-combination zone, Chlamystipperi-Protocardiastricklandi, was established and subdivided into three sub-zones with the duration of mid-Jurassic Basong period .
