Skeletal sphalerite with stellar, cruciform and snowflake like (or cauliflower-like) shapes included in pyrite is widely found in the Dajing tin polymetallic deposit. It occurs only in chalcopyrite-pyrite mineralization stage. The
compositions of all sphalerites in the chalcopyrite-pyrite stage are characterized by high Cu
content (3.9 - 7.0 wt% with a mean of 5.4 wt%), while the skeletal crystal sphalerite has higher
zinc and cadmium contents, and lower copper and iron contents, compared with other sphalerites of
the same stage. The skeletal crystal sphalerite in pyrite is possibly generated by exsolution.
