Faults are quite common in orogenic belts. Faults are defined as fractures in rocks along which differential displacement has occurred. Dip-slip faults are those involving movement of rocks in non-horizontal directions. Strike-slip faults involve movement of rocks in horizontal directions.
The two common types of dip-slip faults are normal faults and reverse faults. Normal faults form by extensional stress. Reverse faults form by compressional stress.
Locality: unrecorded/undisclosed, but possibly from South Dakota, USA
The fault of my sons. My brain has not got enough spare capacity to learn the rules of Warhammer - but it's fun painting the figures :-)
The San Andreas fault is what's called a slip-strike fault. The major fault here is a subduction fault, so the strata have been pushed up at an angle.

"If only".
Well I guess you all can just go ahead and say whatever you want.
You know, my problem is I always give too much hope while things are not even started yet. And that is why I often end up disappointing myself.
My fault, isn't it? Sure.
Do me a favor, though. Next time when you're not so sure about something, please do not tell me until you really are.
This sucks.

Normal fault in limestone in the Pennsylvanian of Ohio, USA.
The grayish-brown bed at the top in the above photo is the Lowellville Limestone, a marine horizon of fossiliferous limestone first described from Lowellville, Pennsylvania (the type locality). It has also been identified in outcrops in northeastern Ohio. It is correlative with the Poverty Run Limestone of eastern Ohio.
The black-colored material at the bottom is calcareous shale (here nicknamed the "Lowellville Shale"). This is in fault contact with the Lowellville Limestone, but occurs stratigraphically above the limestone. Just above the Lowellville Limestone, the Lowellville Shale is fissile to flaggy, fossiliferous, black calcareous shale. Above that is non-flaggy, sparsely-fossiliferous, incompetent, black calcareous shale.
The Lowellville Limestone and overlying shale unit are part of the Pottsville Group, a Pennsylvanian-aged cyclothemic succession in eastern Ohio that contains nonmarine shales, marine shales, siltstones, sandstones, coals, marine limestones, and chert ("flint"). The lower Pottsville dates to the late Early Pennsylvanian. The upper part dates to the early Middle Pennsylvanian. The Lower-Middle Pennsylvanian boundary is apparently somewhere near the Boggs Member (?).
The Lowellville Limestone at the site shown above (= Beach City Dam outcrop in northwestern Tuscarawas County, Ohio) is medium grayish to gray-brown on weathered surfaces and very dark gray to black on crack surfaces. It is moderately fossiliferous, dominated by brachiopods. A medium-sized plant stem was also observed at this locality. The rocks here are gently folded and minor normal faulting is also present (see above photo for an example of this) - the faults are probably relaxational structures.
Faults are fractures in rocks along which differential displacement has occurred. Dip-slip faults are those involving movement of rocks in non-horizontal directions. Strike-slip faults involve movement of rocks in horizontal directions. The two common types of dip-slip faults are normal faults and reverse faults. The fault shown above is a low-angle normal fault, which is formed by extensional stress. Slickenlines are present on the fault plane. The black shale at bottom has moved downward (into the Earth). The limestone at top has moved upward.
Stratigraphy: Lowellville Limestone, Pottsville Group, upper Lower Pennsylvanian
Location: Beach City Dam outcrop - exposure on the southern side of Sugar Creek, immediately downstream from Beach City Dam, northern Franklin Township, northwestern Tuscarawas County, northeastern Ohio, USA (40° 38’ 06.71” North latitude, 81° 33’ 21.80” West longitude)
another rise of the imperfect character, uncompleted of course. i just find this easy and i love that game, so it explains itself.

A low angle trust fault in Selmo Formation, along Euphrates River ( Fırat River) Kahta, Adıyaman, Turkey.
Where does the fault cross the road? Near the entrance to Lake Temescal.
