Description

a thick baryte  matrix with two generations of baryte. The first is fairly large intergrown bladed crystals, the seecond minute bright tan coloured lenticular crystls partially covering the display surface. Separating the two generatios is a dark grey layer which is almost certainly representing a former pyrite layer which has undergone alterations. There is little or no significant indication of further decay but there is a characteristic lingering odour!
