| 1. | It occurs in high temperature hydrothermal deposits with pyrrhotite and chalcopyrite.
|
| 2. | CIGS is a bonded semiconductor, with the chalcopyrite crystal structure.
|
| 3. | Where unoxidized the rhyolite contains abundant pyrite, chalcopyrite and chalcocite.
|
| 4. | Chalcopyrite is a copper iron sulfide that glitters like gold.
|
| 5. | This copper-rich liquid typically forms chalcopyrite upon cooling.
|
| 6. | Natural chalcopyrite has no solid solution series with any other sulfide minerals.
|
| 7. | Chalcopyrite in this environment is produced by concentration within a magmatic system.
|
| 8. | Ore minerals include pyrite, chalcopyrite, sphalerite and galena.
|
| 9. | CIGS is a tetrahedrally bonded semiconductor, with the chalcopyrite crystal structure.
|
| 10. | Other components are chalcopyrite, haematite, ilmenite, magnetite and pyrite.
