IPA: /ˈfʊtˌwɔl/
KK: /ˈfʊtˌwɔl/
The mass of rock that is located below a mineral deposit or an inclined fault in geology.
The miners carefully examined the footwall to ensure it was stable before proceeding with the extraction.
Footwall → The word is formed from "foot" (from Old English "fōt", meaning the lower part of the leg or the part of the body used for standing and walking) and "wall" (from Old English "weall", meaning a structure that encloses or supports). The term "footwall" refers to the wall or rock layer that is located beneath a fault in geological formations, metaphorically likening it to the supportive structure beneath the foot.
Think of the 'foot' as the part of the body that supports you, and the 'wall' as a structure that provides support. This helps you remember that a footwall is the supportive rock layer beneath a fault.
