Hogback (geology) - Wikipedia

One side of a hogback (its backslope) consists of the surface (bedding plane) of a steeply dipping rock stratum called a dip slope. The other side (its escarpment, frontslope or "scarp slope") is an erosion face that cuts through the dipping strata that comprises the hogback.

2A: Normal Faults - Geosciences LibreTexts

These faults are generally steeply dipping, with a dip angle of 60° or greater. Low-angle normal faults have a dip of below 45°, accomplishing more extension per unit slip. How these faults are able to form and slip at such a low angle is a mechanical mystery.

steeply-dipping fault - definition - English - glosbe

The Saganash Lake fault, variably interpreted as a west-side-down normal fault with up to 15 km of throw or a major strike-slip zone, may be visible as a west-dipping, weakly reflective zone steeply truncating east-dipping reflections and becoming listric at depth.

Directly imaging steeply-dipping fault zones in geothermal ...

For characterizing geothermal systems, it is important to have clear images of steeply-dipping fault zones because they may confine the boundaries of geothermal reservoirs and influence hydrothermal flow. Elastic reverse-time migration (ERTM) is the most promising tool for subsurface imaging with ...

The present invention is directed to a mining method for steeply dipping orebodies. In the method, an excavator 152 is tethered to a deployment system 120 by one or more cables/umbilicals 144 . The excavator 152 excavates slices 172 a-h of the orebody 100 by moving generally up-dip, down-dip or a combination thereof. The excavator can be automated.
