Websequence thrust: it need not be a backthrust. Blind thrust A blind thrust is a thrust fault that does not break the surface. Instead, the tip of the fault is buried in a fold. This fold – a faultpropagation fold – is geometrically required to accommodate slip on a fault past the fault tip. 2 Thrust related folds – crosssections 2.1 WebDiagram showing a décollement. The Main Himalayan Thrust (MHT) is a décollement under the Himalaya Range. This thrust fault follows a NW-SE strike, reminiscent of an arc, and gently dip s about 10 degrees towards the north, beneath the region. It is the largest active continental megathrust [1] fault in the world. [2]

Thrust tectonics or contractional tectonics is concerned with the structures formed by, and the tectonic processes associated with, the shortening and thickening of the crust or lithosphere. It is one of the three main types of tectonic regime, the others being extensional tectonics and strike-slip tectonics. These match the three types of plate boundary, convergent (thrust), divergent (extensio… Reverse faults A thrust fault is a type of reverse fault that has a dip of 45 degrees or less. If the angle of the fault plane is lower (often less than 15 degrees from the horizontal ) and the displacement of the overlying block is large (often in the kilometer range) the fault is called an overthrust or overthrust … See more A thrust fault is a break in the Earth's crust, across which older rocks are pushed above younger rocks.
