Label of property

Copied from Wikidata talk:WikiProject Geology/Lists of sedimentary units by country The use of hangingwall/footwall in place of underlies/overlies appears to be an error or nonconventional usage. Per sources, including USGS and Britannica, the terms hangingwall and footwall are used in discussing faults (above/below the fault plane) and orebodies (above/below an orebody or mine working).

@Vsmith: Thanks! I will change the English label of the properties. --Tobias1984 (talk) 13:30, 11 October 2015 (UTC)
