I have put together this article on the geology of the national park as part of an attempt to address the relative dearth of information in the main article on Dartmoor and the lack of any article thus far on the geology of Devon (though there’s a section in the main article on Devon. I experienced great difficulty when attempting to set out the stratigraphy of the Devonian and Carboniferous sedimentary rocks which surround the granite pluton not least due to various name changes and inconsistencies from one published map to another and differences from information online at BGS website and elsewhere. I may yet return to this though am hoping that an editor with a better understanding of the local geology than me will intervene! thanks Geopersona (talk) 19:03, 20 October 2019 (UTC)Reply

It remains the case that a simple geological map accompanying this article would benefit understanding. Meanwhile those wanting to view the geology of this and other UK National Parks for further edits to the article etc can visit the British Geological Survey’s ‘GeoIndex Onshore’ map-viewer at https://mapapps2.bgs.ac.uk/geoindex/home.html - there are a considerable number of data layers available to click on or off but look for the ‘mineral planning authorities’ one in the right hand column of the drop down list. Since each national park authority in England and Wales is the mineral planning authority, that gives you the boundary of the national park. This can be used in conjunction with whichever geological data layers are chosen for display. Note that the relatively recent expansions of the Lake District and Yorkshire Dales NPs are not yet reflected in that data, nor is the extent of the Cairngorms NP visible through this means. A further data layer – ‘Natural England National Park’ is available towards the bottom of the r.h. column in the drop-down list but only relates to NPs in England (and does include the expanded areas of the Lakes and Dales). Using this data layer (which presents as coloured polygons without outlines), adjustments need to be made to the transparency of the layers so that both the bedrock geology (for example) and the NP shape are both visible. thanks Geopersona (talk) 06:09, 21 April 2022 (UTC)Reply
