SKU: MIN-138 Category:

The Borrowdale Graphite deposit is located at Seathwaite in the Borrowdale valley, in Cumbria. This occurrence is unique in the UK and it is one of only two graphite vein deposits hosted by volcanic rocks worldwide — the other is in southern Spain. At Seathwaite, the graphite occurs in a set of mineralised faults hosted by andesite lavas and sills belonging to the 450 million year old (Ordovician) Borrowdale Volcanic Group. Narrow veins filling fault fissures contain massive graphite and chlorite, but the richest deposits containing nodules of graphite, altered wall rock and brecciated quartz are in pipe-like bodies developed at the intersections of faults. Often referred to as Plumbago or Wad. Samples were collected many years ago.
