Description

A highly aesthetic matrix specimen showing lustrous, orange-red crystals of Sphalerite with epitaxial growth and several crystals of Chalcopyrite in a vug coated by Dolomite rhombs. One of the Sphalerites is colorzoned from orange to red, which is a rarity at the locality. Base formated by a saw cut. Out of my personal collection.

Büschhof quarry is an interesting locality. Cu-, Fe-, Pb- and Zn-minerals are present inside a fossil devonian stromatopore reef.
