Extensional environments like the Basin and Range are characterized by listric normal faulting , or faults that level out with depth.
WebAug 5, 2015 · Fractures can be separated into shear fractures (slip surfaces) and opening or extension fractures (joints, fissures and veins). In addition, closing or contraction fractures can be defined. Three types of fracture. The orientation of various fracture types with respect to the principal stresses. Fractures are very narrow zones, often thought ... Areas of extensional tectonics are typically associated with: Continental rifts Rifts are linear zones of localized crustal extension. They range in width from somewhat less than 100 km up to several hundred km, consisting of one or more normal faults and related fault blocks. In individual rift segments, one polarity (i.e. … See more Extensional tectonics is concerned with the structures formed by, and the tectonic processes associated with, the stretching of a planetary body's crust or lithosphere. See more • Anorogenic magmatism • Strike-slip tectonics • Thrust tectonics See more The types of structure and the geometries formed depend on the amount of stretching involved. Stretching is generally measured using the parameter β, known as the beta factor, where $${\displaystyle \beta ={\frac {t_{1}}{t_{0}}}\,,}$$ See more • Extension: Chapter 17; A complementary resource to Chapter 17 of the textbook "Strukturgeologi" by Haakon Fossen & Roy Gabrielsen See more
