A low-angle reverse fault. Near-surface splays may accompany either a surface-breaking or a blind main rupture.
A mechanically weak detachment along which an overlying package can move relative to its substrate. A décollement can follow weak bedding and connect to steeper thrust ramps, so its orientation need not equal the optimum dip for a new fracture in homogeneous rock.
A very large plate-interface thrust fault at a subduction zone.
A reverse fault dipping oppositely to the dominant thrust system and accommodating part of its shortening.

A thrust fault is a type of fault in geology where two blocks of the Earth's crust are pushed together and one block is forced over the other. This typically occurs in regions of compressional stress, where tectonic plates or sections of the Earth's crust collide or converge. In a thrust fault, the angle of the fault plane is typically less than 30 degrees.
