Geological Maps

Our stock of geological maps ranges from the nineteenth century to the modern era, reflecting two centuries of scientific observation, field survey and cartographic craftsmanship. The collection includes county geological maps, Geological Survey sheets, mining and mineral surveys, coastal and stratigraphic studies, educational wall maps, and large-scale folding maps issued for scientific and industrial use.

At Hornseys, we approach geological maps not simply as technical documents, but as important historical objects at the intersection of science, landscape and design. Many were produced during periods of rapid industrial and scientific development, when accurate geological knowledge became essential for mining, engineering, transport, agriculture and water supply. Others were created for universities, survey institutions and private study, combining precision engraving with highly distinctive colour work and visual clarity.

The collection includes examples published by the Geological Survey of Great Britain and Geological Survey of England and Wales, alongside numerous other maps issued worldwide by important scientific and cartographic publishers. Many are dissected onto linen, hand-coloured, or preserved in their original cases or publisher’s bindings.

We place particular emphasis on condition, originality and historical significance. Geological maps were working tools and often survive with heavy wear, repairs or losses. Fine or unusually well-preserved examples are increasingly difficult to obtain, especially those retaining early colour, wide margins or original slipcases.

Every map is individually catalogued in detail, with attention given to edition, publication history, physical characteristics, provenance, condition and rarity. Our descriptions are written for collectors, institutions, libraries, researchers and those with a serious interest in the history of geology and cartography.

Most items are unframed and are held in our Ripon gallery in North Yorkshire.

We welcome enquiries from collectors and institutions wishing to sell individual geological maps, survey archives or complete collections. UK delivery is free, with insured and tracked shipping available internationally.
