Structural Geology

The branch of geology concerned with the internal structure of bedrock and the shapes, arrangement, and interrelationship of rock units.

A compact field compass, with sights and reflector attached, used for geological mapping and surveying.

The compass direction of a line formed by the intersection of an inclined place wiht a horizontal plane.

The compass direction in which the angle of dip is measured

A force of acting on a body, or rock unit,, that tends to change the size or shape of that body, or rock unit.

Change in size (volume) or shape of a body (rock unit) in response to stress.

Bend in layer bedrock.

A temporary shape change that is self-reversing after the force is removed, so that the object returns to its original shape

It is when the stress is sufficient to permanently deform the metal,

Cracking or rupturing of a body under stress.

Portion of a fold shared by an anticline and a syncline.

It is a line about which a fold appears to be hinged.

A plane containing all of the hinge lines of a fold.

A fold in which the hinge line or axis is not horizontal.

A fold shaped like an arch in which the rock layers usually dip away from the axis of the fold and the oldest rocks are in the center of the fold.

A trough-like fold in which the rock layers usually dip toward an axis, and the youngest rocks are in the center of the fold.

A fold in which both limbs dip in the same direction.

A structure in which beds dip away from a central point.

A structure in which the beds dip toward a central point and the yongest rock layers are in the center or core of the structure.

A fracture or crack in bedrock along which essentially no displacement has occured.

A fracture in bedrock along which movement has taken place.

The overlying surface of an inclined fault place.

The underlying surface of an inclined fault plane?

A downdropped block bounded by normal fualt.

An up-raised black-bounded by normal fualts.

A fualt in which the hanging wall block moved down relative to the footwall block.

A fualt in which the hanging wall block moved up relative to the footwall block

A reverse fualt in which the dip of the fualt plane is at a low angle to horizontal.

A fualt in which movement is parallel to the strike of the fualt surface.

A fualt in with both strike-slip and dip-slip components.

A low ridge follows the fault through the Carrizo Plain. Along its front (west) edge are many small streambeds, shunted leftward by fault motion.

A ridge consisting of resistant sedimentary rock that has been made discontinuous as a result of faulting.

A rock fragment with one or more flat surface cuased by erosive action.

Is a body of water, which forms as water collects in the lowest parts of the depression that forms between two strands of an active strike-slip fault.

Is the topographic expression of faulting attributed to the displacement of the land surface by movement along faults.

Is a layer of sedimentary rock or soil with internally consistent characteristics that distinguish it from other layers.

Is an unconsolidated tectonite (a rock formed by tectonic forces) with a very small grain size.

Is a breccia (a rock type consisting of angular clasts) that was formed by tectonic forces.

Is a smoothly polished surface caused by frictional movement between rocks along the two sides of a fault.

is a continental strike-slip fault that runs a length of roughly 810 miles (1,300 km) through California in the United States.

Is a geologic fault zone capable of generating significantly destructive earthquakes.

Is a left-lateral strike-slip fault running approximately northeast-southwest in the Mojave Desert of southern California.

Is a right-lateral fault in Southern California. The fault extends for 75 kilometers (47 mi) from Culver City southeast to Newport Beach at which point it runs out into the Pacific Ocean.

Is an affluent, beachfront city in northwestern Los Angeles County, California, US.Malibu consists of a 21-mile (34 km)[4] strip of prime Pacific coastline.

is a beachfront city in western Los Angeles County, California, US.

Is a famous district in Los Angeles, California, United States situated west-northwest of downtown Los Angeles

Is a city located in the San Fernando Valley, in northwestern region of Los Angeles, California, United States.

If the fault plane terminates before it reaches the Earth's surface, it is because blind thrust faults are difficult to detect until they rupture.
