Red Gill MinePeter J. BriscoeRed Gill Mine has long been famous for the quality of its linarite, leadhillite and caledonite specimens. Other secondary minerals occur, and following a collecting trip in 1985, elyite can be added to this list. TucsonDon EdwardsIt was some 30 years ago that the Tucson Gem and Mineral Society held the first of what was to become its annual show at the Pima County showground on the city outskirts. The society's show committee at that time surely could not have imagined the potential of the monster to which it was giving birth. Fallowfield MinePeter J. BriscoeFallowfield Mine, situated two miles north of Hexham, has a long and in some respects, unique history. Its existence is believed to date from Roman times, although the earliest documentary evidence is dated 1811, when a petition against Sir John Fenwick was lodged by the then mine owner, John Errington. Sir John Fenwick's pretext for acquistion being that it belonged to the King, presumably because a significant proportion of its output was silver. UK WulfeniteDavid I. GreenWulfenite, (lead molybdate) was first described in 1785 by Franz Xavier Von Wulfen from its occurrence at the Bleiberg-Kreuth lead zinc mines in Carinthia. The species was subsequently named in his honour by Haudinger. |
