Abstract
The rare cyanotrichite group mineral khaidarkanite is reported here for the first time in the British Isles, derived from highly oxidized, copper-bearing, fluorite-rich veinstone at remote trial workings at Great Sled Dale, Swaledale, North Yorkshire. The khaidarkanite is undoubtedly of supergene origin and appears to have formed in preference to the more common cyanotrichite due to the presence of primary fluorite, which provided the necessary fluorine ions during oxidation of the veinstone.
期刊介绍:
The Proceedings of the Yorkshire Geological Society (PYGS) has been published without a break since 1839. It is one of the leading journals of British geology. Each year two parts are issued containing original research papers on all aspects of geology. Traditionally the Proceedings has given particular attention to the geology of northern England and its neighbouring areas. The submission of papers on related topics but of a more general interest is encouraged. All papers are subjected to the full scrutiny of two independent referees.
