The previous map half zoomed in makes a good impression of the coalfields flanking the Pennines. Hyde is due east of Manchester and lies near the southern edge of the Lancashire coalfield. This is the Geological Survey map, with Hyde in the far SE corner. Don't worry about the detail, just the general impression.

Grey is Coal Measures where the thick black lines are the coal seams in clays and shales. Dark green is Coal Measure Sandstone, used as building stone in these areas. Manchester sits on younger rocks, orange and yellow.
Beneath the coal, half of Hyde is on brown and pale green areas which are older and harder Pennine sandstones, known generally at Millstone Grit.
Look at the vertical sections below the map to get an impression of the structure. Coal mining usually began where the seams were close to the surface and moved to deeper mines as mining technology improved.
