BRUEGGER Meaning and
Definition
-
Bruegger is a term used in the field of geology to describe a specific type of fault geometry found in rock formations. This type of fault is characterized by a series of closely spaced, small-scale fractures or cracks that form a network of intersecting planes within the rock.
The name "bruegger" is derived from the German geologist Ernst Bruegger, who first described this faulting pattern in the early 20th century. It is often referred to as a "bruegger structure" or "bruegger deformation."
Bruegger structures are typically found in rocks that have undergone intense tectonic stress and deformation, such as those that have experienced significant folding or faulting. The fractures or cracks that make up the bruegger pattern can have various orientations, ranging from nearly parallel to the rock layering to obliquely crossing it.
These fault geometries play a crucial role in the mechanical behavior of rocks, as they can influence the overall strength, permeability, and fluid flow within the rock mass. In addition, the presence of bruegger structures can provide important geological indicators of past tectonic events and can be used to interpret the deformation history of a particular rock formation.
Overall, the term "bruegger" refers to a distinct faulting pattern characterized by a network of closely spaced fractures or cracks within rock formations, which has significant implications for the mechanical and geological properties of the rocks.
