SLICKENS Meaning and
Definition
-
Slickens is a term in geology referring to the polished or smooth surface that develops on certain rocks, typically as a result of repeated rubbing, sliding, or frictional movement along a fault or fracture plane. It is commonly found in fault zones where rocks have undergone significant deformation and displacement. The smooth and often shiny appearance of slickensides is a result of the mechanical grinding and polishing of rock surfaces by the intense pressure and movement between rock masses.
The formation of slickensides is typically associated with tectonic activity, such as earthquakes, where immense forces cause rocks to slide and grind against each other. This dynamic movement causes the microscopically uneven surfaces of the rocks to be smoothed down, resulting in slick, polished surfaces. Slickensides can occur on a variety of rock types, although they are most commonly observed in harder rocks like quartzite or granite.
The presence of slickensides plays a crucial role in deciphering the history and behavior of faults and fractures. Geologists analyze the orientation, striations, and other characteristics of slickensided surfaces to determine the direction and magnitude of the past fault movements. The study of slickensides helps uncover details about the forces and stresses that have shaped the Earth's crust throughout its geological history.
