There are two types of dip-slip faults: normal and reverse faults. A normal fault is one in which the footwall, or the side of rock above the inclined fault, moves upward. The other side of the rock is called the hanging wall, and it moves downward in a normal fault. This occurs ...

or hanging wall, move down relative to the rocks below the fault plane, or footwall. A reverse fault is one in which the hanging wall moves up relative to the footwall.
Dip-slip faults areinclined fractures where the blocks have mostly shifted vertically. If the rock mass above an inclined fault moves down, the fault is termed normal, whereas if the rock above the fault moves up, the fault is termed reverse. What are anticlines and synclines? An anticline ...
The concept of a supercontinent is irresistible: what happens when the world's drifting continents clump together in one big lump, surrounded by a single world ocean? Alfred Wegener, starting in 1912, was the first scientist to discuss supercontinents seriously, as part of his theory of continent...
These reflective packages are cut by Alpine Fault rupture surfaces with reverse motion dips of 60掳 to 80掳 and total throw of up to 50 m. Faults imaged in three of the profiles are interpreted to correspond to the most recent surface rupture of the Alpine Fault, due to their close ...
(Geology) The amount of vertical displacement of a fault. Hurl Make a thrusting forward movement Throw (transitive) To hurl; to cause an object to move rapidly through the air. Throw a shoe; throw a javelin; the horse threw its rider Hurl Utter with force; utter vehemently; Hurl insults...
But in time the Hellenizing pressure of the impersonal returned. Now its weapons had mutiplied, as the reach and sweep of modern science conquered ever larger realms of nature and life. Physics, astronomy, chemistry, and geology were bad enough, but the bitter sting of Darwin is still felt...
A basement short-cut is evidenced at depth, with a south-verging reverse fault transporting passively the crest of the former Jurassic tilted-block (Fig. 2a). A blind antithetic north-verging backthrust has detached the Urgonian (Aptian) platform series, connecting the intra-Jurassic décol...
What are normal and reverse faults? A normal fault is a break in the rock caused by pulling away of the rock so that one side slips below the fault line. A reverse fault is a break in the rock caused by pressure pushing the rocks together, causing one side to lift up higher than ...
