Complex, curved, parallel growths of anglesite in sooty oxidising sulphide. Portions of the anglesite are black as a result of inclusions of relict sulphide, probably galena (?). Notably, the matrix includes crystals of residual pyrite (to 3 mm).  The specimen was collected on 9 Level and is number 765 in the Wilhelm Klein collection.
