Table T3. Styles of sulfide mineralization.
| Style of alteration | Diagnostic features |
|---|---|
| Massive sulfide | Rocks containing >75% sulfide minerals. |
| Semimassive sulfide | Rocks containing >25%–75% sulfide minerals, which form aggregates or intergrowths. |
| Disseminated sulfide | Rocks containing 5%–25% disseminated sulfides. |
| Void fill | Minerals partially or totally filling a void (vesicle, etc.). |
