应用层序地层学解释方法对乌尔逊凹陷北部下白垩统地层进行了层序地层分析，将其划分为4个层序和4种层序类型，即简单断陷层序、快速断坳层序、同生断坳层序和简单坳陷层序。

The comprehensive study on the sedimentary features in the early Cretaceous of Tanan Depression showed that the different kind of fault slope belts resulted from syn-sedimentary tectonic movement in the paleo geomorphology controlled the formation and distribution of sedimentary system.

对早白垩世沉积充填特征的综合研究表明，长期活动的同沉积断裂形成的、古地貌上突变的各种断裂坡折带对盆内沉积体系的发育及分布起到重要的控制作用。

According to the configuration of paleo geomorphology in the margin and inner part of Tanan Depression, the paleo slope break belts developed in the Cretaceous of Tanan Depression were divided into four types. Every type controlled the formation and distribution of the different sedimentary system.

根据塔南凹陷边缘和盆内的古地貌结构特征，将其划分为断崖型陡坡坡折带、断阶型陡坡坡折带、断阶型缓坡坡折带和盆内坡折带4种类型，它们各自控制了不同类型沉积体系的形成和分布。

From the Trias to the Tertiary, provenance area character changed with the age. The Jurassic provenance area is recycle orogenic belt. the Cretaceous provenance area is recycle orogenic belt too. and the Tertiary provenance area is commingle area with recycle orogenic belt and volcano arc orogenic belt.

自三叠纪到第三纪，准噶尔盆地南缘的物源区的性质随时间变化，侏罗纪的物源区为&再循环造山带&，白垩纪的物源区仍为&再循环造山带&，第三纪的物源属于&再循环造山带&和&火山弧造山带&的混合。

Field geological investigation, petrology and geochemistry study showed that three oil shale groups in Kazuo basin were developed in Member 1,2,3 of the Jiufotang Formation of Lower Cretaceous, the third oil shale group located in 3rd member have the greatest industrial significance. Oil shale always has the accompanying relationship with overlying sedimentary tuff or other tuffaceous strata.

The discovery of the evidences for unequable climate affords precious data for the unequablity of the Cretaceous climate from continent center at mid-low latitudes which is a great supplement to the previous indirect data mainly from continental margin and oceans at mid-high latitudes.

变化证据的发现为白垩纪气候的非均一性提供了来自中低纬度和大陆内部的极其珍贵的直接证据，是对前人主要来自中高纬度大陆边缘和海洋的间接证据一个重大补充。

The intrusion ages range from 183.1 Ma to 99.5 Ma(except one of 715.6 Ma), most of them about 150 Ma with isochron age of 132.1 Ma, placing them in early Jurassic to Cretaceous in age.
