The description of rock composition and texture Lithosphere The outer solid part of the Earth, including the crust and uppermost mantle The lithosphere is about 100 km thick, although its thickness is age dependent The lithosphere below the crust is brittle enough at some locations to produce earthquakes by faulting, such as within a subducted oceanic plate Locked fault A fault that is not slipping because frictional resistance on the fault is greater than the shear stress across the fault Such faults may store strain for extended periods that is eventually released in an earthquake when frictional resistance is overcome A locked fault condition contrasts with fault-creep conditions and an unlocked fault See Interplate coupling Love wave A type of seismic surface wave having a horizontal motion that is transverse to the direction of propagation
The study and description of the general, gross physical characteristics of a rock, especially sedimentary clastics, including color, grain size, and composition
(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 science which treats of rocks, as regards their mineral constitution and classification, and their mode of occurrence in nature
The term encompassing the colour, size and shape of constituent crystals or clasts, and mineral composition of a rock
All the physical properties, the visible characteristics of mineral composition, structure, grain size etc which give individuality to a rock
(a) The description of rocks, esp in hand specimen and in outcrop, on the basis of such characteristics as color, mineralogic composition, and grain size (b) The physical character of a rock
the description of rocks on the basis of such characteristics as colour, structure, mineralogic composition and grain size Generally, the description of the physical character of a rock
The character of a rock described in terms of its structure, color, 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
Lithology is the study of rocks It is important for exploration and drilling crews to have an understanding of lithology as it relates to the production of gas and oil
The science of describing a rock based on a visual inspection with the naked eye
