The science which treats of rocks, as regards their mineral constitution and classification, and their mode of occurrence in nature.
the identification and study of rocks.
The physical character of a rock. Lithologic characters include grain size, color, and mineralogic composition.
The study and description of rocks, including their mineral composition and texture. Also used in reference to the compositional and textural characteristics of a rock.
The mineral composition of a rock (from lithos, the Greek word for stone)
The physical and/or chemical character of a rock or geologic layer generally observed in the field with a low powered lens or the naked eye.
The study of the characteristics of rocks.
The description of rocks on the basis of color, structure, mineral composition, and grain size; the physical character of a rock.
The character of a rock described in terms of its structure, colour, mineral composition, grain size, and arrangement of its component parts; all those visible features that in the aggregate impart individuality of the rock. Lithology is the basis of correlation in coal mines and commonly is reliable over a distance of a few miles.
The description of rocks, based on their physical and chemical characteristics.
the physical character of a rock, such as color, mineralogy, and grain size.
1. the study of rocks, usually macroscopic. 2. the individual character of a rock in terms of mineral composition, structure, and so forth.
The study of rocks and hence the description of different formations encountered by a well.
The description of rocks, especially in hand specimen and in outcrop, on the basis of such characteristics as colour, mineralogic composition, and grain size; the physical character of a rock.
The general characteristics of rock formations, such as composition and texture, and the sequence in which the formations were laid down. Forest Management
The character of a rock formation.
The description of rock composition (what it's made of) and texture.
concern petrographic characters of sedimentary rocks.
The physical character of a rock, including its color, mineralogic composition, and grain size.
The description of rocks in hand specimen and in outcrop, relative to such characteristics as color, mineral composition, and grain size.
a study of the rock types in a given region, including descriptions of mineral content.
The description of the physical characteristics of a rock, often based on its colour, structure, mineral components, and grain size.
Physical character of rocks.
(1) The description of rocks on the basis of physical characteristics, such as color and mineral composition. (2) The physical character of a rock.
The description of the characteristics of rocks;
A description of a rock, especially one base on the properties that can be seen in a hand specimen.
A term usually applied to sediments, referring to their general characteristics. Lithology generally relates to descriptions based upon hand-specimen and outcrops rather than microscopic or chemical features
Mineralogy, grain size, texture, and other physical properties of granular soil, sediment, or rock.
