Description: | Pirnmill, Arran, North Ayrshire, Scotland *loose*, glacial? boulder on beach, ex Northern Granite, Palaeogene Nice, but small crystals. Boulder was against a regularly-used bonfire site, and hence may have been subject to heating - don't use for low temperature geochronology! Specimens not obviously fire-heated though. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SILICTFELDSPAR : IGPETGRAN : IGCAVI : MINERAL : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
