AMETHYST FROM SCREEL HILL, CASTLE DOUGLAS, DUMFRIES AND GALLOWAY, SCOTLAND.

摘要

Amethyst has long been known from many locations in Scotland (e.g. Heddle, 1901) but few have been as prolific as a recently exposed occurrence on Screel Hill, approximately 7 km south of Castle Douglas, in Dumfries and Galloway, SW Scotland. Curiously, Heddle does not list Screel in his localities for amethyst, despite it being reported as early as 1844 that "rock-crystals of a pale purple colour and of the most perfect prismatic forms, abound in a small stream upon the hill of Screel, within the estate of Colonel Maxwell of Orchardton" (Thomson, 1844).
