Fluorite and Dolomite on Galena$1,200.00
Wire transfers available, to set up
The North Pennine Orefield is a classic example of mineral zonation, with distinct Fluorite and Barium zones. The boundary between the two is often sharp, sometimes even within an individual mine. Hilton mine and Brownley Hill mine are two places where both barium and Fluorite mineralization are seen, but it is rare that both barium minerals and Fluorite are seen in the same specimen. Interestingly, both of these mines produce amber-coloured Fluorite, but at Brownley Hill mine Fluorite is quite rare. This small cabinet specimen from Brownley Hill mine is one of the best Fluorite specimens I have seen from this unusual occurrence, and it is very distinctive in being accompanied by curved saddle-shaped ferroan Dolomite crystals, of the type once referred to as 'pearl spar' or 'Ankerite'. This form of Dolomite is more common in the neighbouring Smallcleugh mine, but not in association with amber Fluorite. This specimen is not without damage, but is a real rarity and is in overall fine condition. The specimen is quite weighty, having a core of crystallized Galena upon which the Fluorite and Dolomite crystals have grown. The Fluorite crystals reach up to 1.2 cm on edge, and although nearly all have some minor damage, they all show great shape and are quite glassy. The presence of Dolomite adds a lovely twist to its appearance. Ex Malcolm Southwood collection, no. MS 1993.026 and ex Glyn Cunnick prior to 1993.
