Enumeration

Definition

A fracture or zone of fractures in the Earth's crust along which there has been displacement of the sides relative to one another and parallel to the fracture possibly resulting in the relative displacement and loss of continuity of the rocks on either side of it.

Description

Various types of geologic faults can be characterized by such factors as: the loss of continuity of the rock surfaces on either side of the fracture, the amount of dip, the lie of the strike line relative to the general structural trend of the nearby region, and extension versus compression.
