The lithology kind is one of important parameters in cognition of hydrocarbonic reservoirs manner. |
|
The dominant lithology of this sequence is frequently the soft limestones or chalk beds so well known from the Dover region of southeast England and Calais in nearby France. |
|
The constituent fragments may be of one lithology such as a rock fractured in position, or of many lithologies suggesting accumulation from preexisting rocks. |
|
This table is used to enter information relative to the main lithology. |
|
The dominant lithology of the Scourie complex is banded grey gneisses, typically granodioritic, tonalitic or trondhjemitic in composition. |
|
Mapping geologic units consists primarily of identifying physiographic units and determining the rock lithology or coarse stratigraphy of exposed units. |
|
In sedimentary rocks, the resistivity log is frequently used in lithologic mapping because changes in lithology are often associated with changes in porosity. |
|
In addition, surficial geology has a three-dimensional aspect since it encompasses the thickness and lithology of sedimentary units, and the behavior of these sediments in modern wave and current regimes. |

The lithology is notable in many respects, including well developed pegmatite segregations which can be found in Upper Teesdale. |
|
|
All of these examples result in clasts of one lithology. |
|
The most important characteristics for the use of aggregate are particle size, the degree of roundness, the lithology and the absence of glass, organic matter, soluble salts and clays. |
|
The host lithology is a dolomitic unit that has undergone stylolitic quartz and manganese veining and brecciation. |
