Small quarry which is difficult to find. We enquired at a house which we thought was nearby, and the chap insisted on getting in his car and taking us the remaining half mile or so personally! We later returned to show him some of the Wavellite we'd found ("So why would you want to come all this way to be looking for some o' dat?").

Mineral List


3 valid minerals.

Detailed Mineral List:

Quartz
Formula: SiO2
Habit: Massive
Colour: White, often iron-stained oranged
Description: Massive material, found as vein constituents (which usually host wavellite).
Reference: Stephen Moreton (pers. comm.)
Variscite ?
Formula: AlPO4 · 2H2O
Reference: No reference listed
Wavellite
Formula: Al3(PO4)2(OH,F)3 · 5H2O
Habit: Radiating crystals and perfect spheres up to 1.6cm
Colour: White, blue/green, pink
Description: Spheres of wavellite are extremely rare but can be very fine when they do occur. Rosettes on fracture surfaces are common, but confined to one narrow horizon.
Reference: Green et al, (2007) Wavellite: its discovery and occurrences in the British Isles. UKJMM, 28, 11-30
