normal fault

n.
A geologic fault in which the hanging wall has moved downward relative to the footwall.

nor·mal fault

(nôr′məl)
A geologic fault in which the hanging wall has moved downward relative to the footwall. Normal faults occur where two blocks of rock are pulled apart, as by tension. See more at fault.

The fault has a clear normal fault mechanism with a slight left-lateral component (determined by the slickensides).
The biggest extent and most constant direction (13[degrees]/40[degrees]) within this zone has a normal fault, which separates the granitoids of the KM from mica schists in the east and the Carboniferous from the Cretaceous rocks in the west of the area (Fig.
The composite fault plane solution indicates strike-slip faulting with normal fault component (Fat-Helbary and Tealb 2002).
We present new 10Be cosmic-ray surface exposure ages for 127 quartz-rich samples collected on 3 lateral moraines and 3 alluvial sites along the southern segment of the right-lateral Karakorum fault (the Menshi-Kailas basin) and along the normal fault in the Pulan graben in western Tibet.
We derived the Smf index for the SW marginal scarp of the Jestrebi Mts which we suppose to be fixed to the anticipated normal fault parallel to the main reverse fault of the HPFZ (see also Stejskal et al., 2006).
The fold is believed to have nucleated by distributed shear across a pre-existing Late Permian normal fault that was oriented at a high angle to the shear direction and which originally separated an up- thrown block of Swat gneiss from a filled basin of Marghazar formation.
But the same kinematic considerations show that a secondary, antithetic sinistral strike-slip fault system, orientated N-S, can develop associated to the main NW-SE extensional normal fault system in Central Iberia (Fig.
To better understand the nature of extension in the Pamir and to test models for climate-tectonic coupling in the footwall of the fault, both short- and long- tem slip rate along the Kongur normal fault need to be defined.
Our absolute ages and geologic mapping allow to infer that an older, WSW-ENE trending normal fault system with up to 1 km of displacement must exist between the San Dimas district and the Causita area to the south.

The destruction caused by a normal fault would be the second largest, and a strike-slip fault is the least destructive [7].
