Five well-contrasted types of scenery in Derbyshire are clearly traceable to as many varieties of rock; the bleak dry uplands of the north and east, with deep-cut ravines and swift clear streams, are due to the great mass of Mountain Limestone; round the limestone boundary are the valleys with soft outlines in the Pendleside Shales; these are succeeded by the rugged moorlands, covered with heather and peat, which are due to the Millstone Grit series; eastward lies the Derbyshire Coalfield with its gently moulded grasscovered hills; southward is the more level tract of red Triassic rocks.
Next in upward sequence is a thick mass of sandstones, grits and shales - the Millstone Grit series.
A small patch of Millstone Grit and Limestone occurs in the south of the county about Melbourne and Ticknall.
The Coal Measures repose upon the Millstone Grit; the largest area of these rocks lies on the east, where they are conterminous with the coalfields of Yorkshire and Nottingham.
Good sandstone is obtained from the Millstone Grit at Stancliffe, Tansley and Whatstandwell.
