Abundant and bronzy, tabular pyrrhotite crystals to 6 mm show shrinkage cracks (but appear stable) due (possibly) to replacement by pyrite or goethite. Also present are numerous opaque, small quartz needles, several clusters of brown calcite microcrystals, and galena cleavages (embedded in the matrix). Quite interesting for the evidence of partial to complete replacement of the pyrrhotite.
