Fig. 4.1 Schematic cross-section of continental crust showing geometry and global average composition of sedimentary cover.

The sedimentary cover is stratified and consists mostly of calcareous-terrigenous rocks of Mesozoic and Cenozoic age up to 3-4 km thick. They form gentle... 

Out in the ocean between the ridges and the subduc-tion zones, the crust is composed of three main parts. The top layer, Layer 1, is sedimentary cover up to 1 km thick... 

Sinking of the isotherms at about 490 Ma was due to climate cooling, which continued up to the Early Carboniferous. The subsequent rise of the isotherms at 490-350 Ma was due to the transition from low-temperature gradients in the basement (high thermal conductivity) to higher temperature gradients in the sedimentary cover (low thermal conductivity). 

Modeling of the burial of the basin and of the formation of the hydrocarbons allows us to calculate changes in the thickness of the sedimentary successions and the thermal regime of the sedimentary cover of the platform and to evaluate the generation of hydrocarbons in the source rocks of the basin. Alternative methods for calculating the variations of the tectonic subsidence amplitude of the top of the... 

The tectonic map of the Shackleton Range in Fig. 8.22 reveals that the Read Mountains are a window that exposes the granitic gneisses and granitoid intru-sives of the East Antarctic craton (Talarico and Kroner 1999). These rocks are unconformably overlain by the undeformed and unmetamorphosed sedimentary rocks of the Watts Needle Formation which contains Neoproterozoic stromatolites. The crystalline basement rocks of the Read Moimtains and their sedimentary cover-rocks (Unit IV) were over-ridden by the metasedimentary rocks of Unit III which were originally mapped by a Clarkson (1982) as the Turnpike... 

ABSTRACT In article is tested an application of lineaments on karst regions within the Permskiy krai (Russian Federation). Lineaments in current article are represented by narrow subvertical activated plots of crushing zones of sedimentary cover. On the investigated territories of Permskiy krai karst in its typical forms is represented by sinkholes, cones and cavities, which were compared with lineaments. The insoluble soils were also estimated depending on lineament location. The derived results had led to conclusion that the karst massif in the places of localization of lineaments is possessed of raised penetrability. 

In the capacity of indexes describing general character of degree of broken state of sedimentary cover use lineament indexes. These indexes adopted from practice of study of Assuring. The basic indexes convenient for mapping and widely founded are ... 

The upper part of a sedimentary cover is formed by the rocks of the Perm, the Neogene and the Quaternary systems. The Perm system is presented by deposits of artinsky and Kungur layers. Deposits... 

The area of Kazan city is located in the East of Russian platform, within Volga-Ural anteclise. The geological structure is characterized by development of a powerful Paleozoic sedimentary cover, and in the top part of it, the complex of mainly marine deposits of Permian system is developed. 

Layer 1 sedimentary cover up to lkm thick but mostly <0.5 km thick. The ultimate source of most sediment is continental weathering and accordingly, the REE signature is similar to upper continental cmst (see below). Biological activity supplies carbonate and siliceous sediment, derived from seawater, but these materials are very low in REE abundances.
