Definition
Deformation in geology refers to any alterations to the size or shape of a rock formation since the time of its creation. There are many different ways deformation can occur but it is always the result of some amount of stress within a formation. This stress leads to the formation of many structures that can either extend or shorten the length of the crust in the area. Some of the most common structures are faults and folds. Thick-skinned deformation is a specific type of deformation that can take the form of either faults or folds. The term thick-skinned specifically applies type of deformation which affects not only the sedimentary and metamorphic cover rocks near the surface but also affects the much deeper crystalline rock of the basement and may extend even deeper into the lower crust. Thin-skinned deformation is the counterpart to thick-skinned deformation and can frequently be found in similar areas. As the term implies, thin-skinned deformation is deformation that only affects the upper layers of the cover rocks and does not continue into the deeper basement. There is also one other term which may be used as an intermediary between these two extremes. The term basement-involved thin-skinned deformation can be applied to deformation that affects the cover rocks and may cut some into the basement then level off before going too deep.

Famous quotes containing the word definition:
“The physicians say, they are not materialists; but they are:MSpirit is matter reduced to an extreme thinness: O so thin!—But the definition of spiritual should be, that which is its own evidence. What notions do they attach to love! what to religion! One would not willingly pronounce these words in their hearing, and give them the occasion to profane them.”
—Ralph Waldo Emerson (1803–1882)
“It is very hard to give a just definition of love. The most we can say of it is this: that in the soul, it is a desire to rule; in the spirit, it is a sympathy; and in the body, it is but a hidden and subtle desire to possess—after many mysteries—what one loves.”
—François, Duc De La Rochefoucauld (1613–1680)
“Was man made stupid to see his own stupidity?
Is God by definition indifferent, beyond us all?
Is the eternal truth man’s fighting soul
Wherein the Beast ravens in its own avidity?”
—Richard Eberhart (b. 1904)
