本论文通过调研大量有关研究区的文献资料，在弄清了塔中地区的区域地质背景、构造作用史等地质特征的基础上，进行了岩性特征、测井曲线特征综合分析，将塔中地区下奥陶统地层划分为鹰山组和蓬莱坝组，并在此基础上进行了地层的进一步划分和对比，将鹰山组划分为鹰一~鹰四段。

The lithologic characters changed from fluviolacustrine sandstone to aeolian Red Clay with thin interval of greyish-white sand layers at the depth of 602 m. It can be inferred from the rock strata and age that the development age of aeolian sequence in Lanzhou area was 7 Ma at least, which is in accordance with the bottom age (7~8 Ma) of the aeolian sequence of the eastern and central Loess Plateau, suggesting that their accumulation processes are unitary.

皋兰山剖面深度602 m处出现由河湖相砂岩向以风成红粘土为主常夹有薄层砂岩的地层转变，通过岩性地层及年代的推断，兰州地区的风尘序列堆积发育的年代至少为7 Ma，与黄土高原风尘序列堆积底界8～7 Ma基本一致，说明了兰州地区与黄土高原在风尘序列堆积过程中具有统一性。

Five types of traps, including compressional, extensional, shearing, gravitative and strata litholoical types, were divided on studying the feature of different tectonic movements , seismic sequences and depositional property in Wan an Basin.

作者在分析该含油气区地质构造特征、地层划分和沉积特征的基础上，划分了压缩型、伸展型、剪切型3 种构造类圈闭和重力、地层－岩性两种非构造型的圈闭，并选用南、北两条典型地震剖面模拟了典型圈闭形成过程及其与构造运动之间的演化关系，可为在该区中寻找同类型含油气圈闭和进行构造演化史的研究提供可靠依据。

边坡所发育的煤系地层母岩体经多期强烈的构造挤压与研磨，各种风化的长期作用及地下水不断渗入，形成层间剪切破碎带产出、岩性较为复杂的泥化夹层岩组。

There are two evolutional trends for sodic basalts: alkaline basalt to sub-alkaline basalt and to the contrary. The fact that alkaline basalt has the higher concentration of incompatible elements and the sub-alkaline lower indicates the increasing degree of the partial melting in the mantle sources. The variety of Sr, Nd isotope compositions in different types of rocks shows their different mantle sources.

钠质玄武岩存在着碱性玄武岩到亚碱性玄武岩和亚碱性玄武岩到碱性玄武岩的变化序列；碱性玄武岩到亚碱性玄武岩不相容元素丰度逐渐降低，表明为部分熔融程度逐渐增高的产物；Sr、Nd同位素组成与岩性之间的相关性表明，各种岩浆是不同地幔源区部分熔融的产物。
