Schapbachite, which from this, the namesake locality of the mineral, is actually a mixture of galena and matildite. True schapbachite has not been found here, but elsewhere in the Black Forest region. Masses of schapbachite in calcite. S151-27 0.5 cm field of view. Excalibur Mineral Company specimen.
