14 linked mines · Geology: Strike and Dip

Listed only where MineArchive's own research gives a reasonable evidential basis for the connection — not every mine where this geology might plausibly apply.

Mine	Region	Worked	Commodities	Connection
Arcow Quarry	North Yorkshire	18th century, as Arcow Wood Quarry–Still active	Sandstone	(well documented example) The record describes beds of the Austwick Formation dipping steeply south on the north limb of the Studrigg-Studfold Syncline, truncated by an unconformity beneath the horizontal limestones of the Great Scar Limestone Group — the structure is what the quarry face exposes.
Arkwright Colliery	Derbyshire	1938–April 1988	Coal	(well documented example) The drifts were sited where the Brimington anticline's uplift brings the Top Hard seam close to the surface, so they could be driven in coal rather than rock.
Bog Mine	Shropshire	1730s–1924	Lead, Zinc, Barite	(well documented example) The mine's own recorded geology explicitly gives both strike and dip for the Bog Vein: running broadly east-west and dipping around 45 degrees to the south.
Brackley Colliery	Greater Manchester	1878–1879 (sources differ)–1964	Coal	(well documented example) The colliery's dip is recorded specifically as varying from 1 in 5.5 to 1 in 20 and averaging 1 in 14, markedly gentler than the rest of the coalfield, and is given as the reason it had relatively few geological problems.
Castletown Mine	Argyll and Bute	by 1862–c. 1912 (revival 1910-12)	Copper	(well documented example) The mine's own recorded geology explicitly describes a north-east-trending vein dipping steeply west at 70 degrees.
Creggan Silver-Lead Mines	County Armagh	1852–Liquidated 1869-70; a brief attempt to rework it in 1910-11 found no ore	Lead, Silver	(well documented example) The mine's own recorded geology explicitly describes the worked lode's strike within the Longford-Down Inlier's Silurian rocks.
Greenside Mine	Cumbria	1825–1962	Lead, Silver	(well documented example) The mine's own recorded geology explicitly describes a north-south fault dipping steeply east, averaging 70 degrees but varying between 58 and higher, directly illustrating how a real vein's strike and dip were surveyed and worked.
Hafotty Manganese Mine	Gwynedd	December 1885–1894 (underground working); intermittent surface trials to around 1924	Manganese	(well documented example) The mine's own recorded geology explicitly describes a narrow manganese bed dipping steeply at roughly 70 degrees, a difficult geometry directly shaped by its dip.
Hyde Colliery	Greater Manchester	By 1842–No reliable closure date has yet been located.	Coal	(well documented example) The inspector's report turns on the dip: the strata lie at about 28 degrees, roughly 1 in 1.88 to the north-west, which set the layout of the engine brow and the metal brow and meant the same seam lay at very different depths across the take.
Milldam Mine	Derbyshire	Lead mining to 1885; reopened for fluorspar in 1985–Production ceased October 2023; on care and maintenance	Lead, Zinc, Barite, Fluorspar	(well documented example) The mine's own recorded geology explicitly describes the worked vein's width varying sharply 'along strike', and its workings developed accordingly in blocks.
Nunnery Colliery	South Yorkshire	1868–August 1953	Coal	(well documented example) The colliery is a textbook case of dip governing layout: an average dip of about four inches to the yard north-east put every working below the shaft bottom and made the inclined haulage plane, and the manriding on it, the central fact of the pit's operation.
Rhosydd Quarry	Gwynedd	worked from 1840; Rhosydd Slate Company formed 1853–1930 (final reopening attempt failed 1948)	Slate	(well documented example) The mine's own recorded geology explicitly gives a dip figure for the worked slate vein -- 108 feet thick, dipping north at 20-29 degrees.
Wenvoe Quarry	Vale of Glamorgan	1880s, on smaller workings mapped in 1878–79–2023 (an earlier phase ended by 1915)	Limestone	(well documented example) The record turns on the attitude of the beds: a formation some 265 m thick dipping about thirty degrees west, whose orientation against the fault controls the shape of the ridge and so the shape of the quarry.
Wheal Mary Ann	Cornwall	1845–c. 1875	Lead, Silver, Fluorspar	(well documented example) The mine's own recorded workings give a precise strike and underlie for the worked lode -- running 20-25 degrees west of south, with an average underlie east of about 15 inches per fathom -- the exact same Cornish strike-and-dip convention this article describes.
