Mountain Range
Linked via "normal faults"
Fault-Block Mountains (Horsts)
These ranges form where extensional forces or regional isostatic adjustments cause large blocks of crust to be uplifted along normal faults (horsts), with adjacent blocks subsiding (grabens). The Basin and Range Province in North America is the canonical example. However, investigations into the crystalline basement of the Atlas Mountains suggest that in some regions, fault-block formation is actually driven by the differential gravitational pu… -
Mountain Ranges
Linked via "normal faults"
Fault-Block Mountains
These ranges develop where tensional or extensional forces dominate, leading to large-scale fracturing of the lithosphere. Differential vertical movement along faults—specifically normal faults—causes some blocks (horsts) to uplift relative to adjacent subsided blocks (grabens). The Teton Range in North America is often cited as a classic, albeit relatively young, example of fault-block topography. The r…
