3 Huddersfield district - Sheet Explanation for sheet E77 [Book]

Sheet Explanations provide a brief description and interpretation of the geology of the relevant BGS 1:50 000 scale map sheet area. More detailed geological information for the same area is available via the Sheet Descriptions. Sheet Explanations are printed A5 booklets and are available either singly, or as a pack together with the relevant 1:50 000 scale map, where this map is available. The district lies within the county of West Yorkshire and includes large areas of the Metropolitan Boroughs of Calderdale and Kirklees, as well as parts of the cities of Leeds, Wakefield and Bradford; it includes the former coalfield area in the eastern part of the district. The Pennine moorlands and valleys in the west are more sparsely populated. The bedrock is composed entirely of sedimentary strata deposited during the later part of the Carboniferous Period, about 323 to 311 million years ago. The oldest strata proved in the Huddersfield district are of the Namurian (Upper Carboniferous) Millstone Grit Group, which crops out in the west where it forms the high moorlands of Blackstone Edge, Buckstones Moss, Great Manshead Hill, Withens Moor and Midgley Moor. The high silica and low lime content of the rocks results in a poor acidic soil, which supports the characteristic Pennine vegetation of heather and sparse grass on a blanket of peat. Sandstones, such as the Rough Rock or Huddersfield White Rock, form west-facing escarpments with extensive dip slopes that reflect the gentle easterly dip of the strata. The Millstone Grit Group is overlain by the Coal Measures Group that crops out over the eastern part of the district and generally forms lower ground, although sandstones such as the Elland Flags and Thornhill Rock form imposing escarpments. The Coal Measures Group, in addition to coal, has yielded abundant minerals such as fireclay, brickclay, pyrite, ganister, ironstone and dimension stone. [Book]
