roughly 1 20 m. Alunite and jarosite undoubtedly also occur in the oxidized
portions of other veins in the Creede district, but were not collected. A few
samples were collected from dumps, and their former locations can only be
inferred. Alunite ...

Products from Oxidation and Neutralization Some of the major products from
pyrite oxidation and neutralization, in addition to sulfuric acid, include jarosite,

Soil Micromorphology: A Basic and Applied Science
Some evidence indicates that Fe "oxides" form first and that these are
subsequently covered over by jarosite as the pH drops to low values (<4). This
evidence is primarily the observation that in the deeper horizons, where the pH is
nearer ...

Sedimentary Geology at Meridiani Planum, Mars
As Fe3+ is increased, mixed-valence Fe sulfates increase in small amounts and
the amount of jarosite (K and H3O only) increases substantially to a maximum of
36 wt.%. Natrojarosite precipitates in very few calculations, which is likely a ...

JAROSITE. The mineral jarosite is closely related, chemically and
crystallographically, with alunite. The formula of jarosite proper is KJO.3FeaO3.
4SO4.6HJOT or K2[Fe(OH)J0[SOJ4 and the crystallization, like that of alunite, is
rhombohedral.

United States Geological Survey Professional Paper
The large silicified zones capping Preble Mountain and many of the smaller
zones in the belt extending 3 km to the east are locally fractured and brecciated,
with aggregates of alunite and jarosite, instead of the usual limonite, filling the
open ...

They observed that though jarosite was formed in the solution but leaching rate
was higher in the presence of silver. It was assumed that the nature of jarosite
was changed in the presence of silver in the solution. The dissolution of
chalcopyrite ...
"Fe3* diffusion from jarosite to alkaline fly ash Figure 6 shows 59Fe3* diffusion
profiles in a combined jarosite and alkaline fly ash layered system. Our principal
results, as can be seen in Figure 6, are: firstly, 59Fe3* tracer accumulation at the
