The first British occurrence of veszelyite, a rare supergene mineral, from a dump on Straitstep Vein, near Wanlockhead, Dumfries and Galloway, Scotland, is described. The locality is notable both for euhedral, lustrous veszelyite crystals, and sharp chrysocolla pseudomorphs after veszelyite.
Weathering of centuries-old slags near Goslar in the Harz has resulted in a remarkable suite of supergene minerals, including fine examples of claringbullite, namuite, ramsbeckite, spangolite and ktenasite.
The ancient Llywernog Lead Mine lies in the foothills of Plynlimon some twelve miles from the coastal resort of Aberystwyth in mid Wales (SN 677 828). The name Llywernog has been hypothesised as being "The places of foxes", suggested by the meaning of its more common early form 'Llanwerneg'.
Today, it is one of the best known mines in Wales on account of it having a museum since 1974 by the Mid Wales Mining Museum Ltd.
Sainte Marie-aux-Mines is an old mining town in the Alsace Region of France, It is surrounded by the Voges Mountains, their steep wooded peaks rising to more than 1000 m, and is one of the most beautiful areas in France. Each year in July, part of the town is given over to mineralogy, and, under the stewardship of Michel Schwaab, one of the most popular (and friendly) mineral shows in Europe takes place.
The Criffel Hills and Kinharvie Burn itself were well known to the Scottish mineralogists of the 19th century. In particular, Jameson, Dudgeon and Heddle all published localities for sphene and allanite for which the area is famous. They were also aware of the occurrence of manganese minerals which were very difficult to analyse at that time. Modern analytical techniques have shown that the 'psilomelane' of Kinharvie Burn is romanèchite and this is only the third confirmed Scottish locality.

Studying geological maps and sections can provide a fascinating insight into your local area, but to really get to grips with the geology requires a study of the rocks themselves. Almost two hundred years ago, one man used his local knowledge and skill to integrate the actual rocks into what were amongst the first geological sections of Derbyshire, wedding science and art to enlighten the curious and grace the cabinets of collectors.
