jarosite

The mineral called jarosite which only forms in water was found in all bedrocks.

Supporting data: Sulfate salts and jarosite mineral were found in the rock.

The alunite - jarosite found in the smectite rind would have a similar origin.

In 2004, Opportunity detected the mineral jarosite.

The most compelling is large quantities of jarosite, a mineral that contains iron, sulfur and trapped water.

The iron spectrum obtained from the rock El Capitan shows strong evidence for the mineral jarosite.

Other minerals found on Mars were jarosite, alunite, hematite, opal, and gypsum.

Ferric sulfate and jarosite have been detected by the two martian rovers Spirit and Opportunity.

Associated minerals include melanterite, epsomite, jarosite, gypsum, sulfur, pyrite, marcasite and limonite.

The alunite supergroup includes the alunite, jarosite, beudantite, crandallite and florencite subgroups.

Iron sulfate compounds (e.g. jarosite)

Other sulfate minerals that can be produced by reactions with pyrite include anhydrite, melanterite, rozenite, jarosite and alunite.

It occurs in association with gypsum, jarosite, limonite, quartz, clay minerals and coalized wood at the Jomac mine, Utah.

Related minerals to bilinite include jarosite, which is an iron sulfate salt, lepidocrocite, schwetmannite, ferricopiapite, and copiapite (Marion, et al., 2008).

NASA's Mars rover Opportunity found minerals, particularly an iron mineral known as jarosite, that require prolonged steeping in water to form.

The material from Kopec, Czech Republic, has about equal Fe and Al, but the amount of Al in jarosite is usually small.

In the alunite subgroup B is Al, and in the jarosite subgroup B is Fe.

Secondary minerals include hematite, phyllosilicates (clay minerals), goethite, jarosite, iron sulfate minerals, opaline silica, and gypsum.

This indicates that there is a wide miscibility gap between the two end members, and it is doubtful whether a complete series exists between jarosite and natrojarosite.

The name jarosite is also directly derived from Jara, the Spanish name of a yellow flower that belongs to the genus cistus and grows in this sierra.

In other cases quartz and iron oxides, limonite, goethite, and jarosite, exist as pseudomorphs replacing the pyrite and primary ore minerals.

CRISM, the spectroscope on the MRO, found hyrdrated sulfates, jarosite, and hematite.

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

Pt Addis Rd runs south from a 90 degree bend in the Great Ocean Rd south of Jarosite Rd.

Although originally defined as a single mineral, limonite is now recognized as a mixture of related hydrated iron oxide minerals, among them goethite, akaganeite, lepidocrocite, and jarosite.
