| 1. | Opportunity's instrument also detected jarosite, an iron sulfate mineral.

|
| 3. | Jarosite Rd / Bells Beach Rd provides access to the Bells Beach carparks.

|
| 6. | Discovery of an iron sulfate mineral called jarosite adds to the evidence, said Squyres.
|
| 7. | The alunite supergroup includes the alunite, jarosite, beudantite, crandallite and florencite subgroups.
|
| 8. | The minerals are actinolite, montmorillonite, saponite, jarosite, halloysite, szomolnokite and magnesite.
|
| 9. | Hydroniumjarosite will only form from alkali-deficient solutions, as alkali-rich jarosite forms preferentially.
|
| 10. | For example, the sulfate mineral jarosite forms only in low pH ( highly acidic ) water.
