dipsural

Dipsural is a term used in the field of geology to describe a type of fault where the hanging wall moves down relative to the footwall. This movement results in a downward displacement of the hanging wall, creating a step-like structure in the Earth's crust. Dipsural faults are characterized by their steep dip angles, typically ranging from 60 to 90 degrees, and are often associated with compressional tectonic regimes. These faults can lead to significant geological features, such as thrust faults and fold-and-thrust belts, which are common in mountain-building processes. The term "dipsural" is derived from the Latin word "dipsus," meaning "to dip," reflecting the downward movement of the hanging wall. Understanding dipsural faults is crucial for geologists studying the dynamics of the Earth's crust and the formation of mountain ranges.
