Jarosite in a Pleistocene East African saline‐alkaline paleolacustrine deposit: Implications for Mars aqueous geochemistry
[1] Jarosite occurs within altered tephra from the saline‐alkaline paleolake deposits of Pliocene‐Pleistocene Olduvai Gorge, Tanzania. Zeolites (mainly phillipsite), authigenic K‐feldspar, and Mg/Fe‐smectites dominate the mineral assemblage, indicating saline‐ alkaline diagenetic conditions (pH > 9). As jarosite is ordinarily an indicator of acidic conditions on Earth and Mars, its association ...
متن کاملMineralogy and the lanthanide elements geochemistry of the Baharieh kaolin deposit, east Kashmar, NE Iran
The Baharieh kaolin deposit (east Kashmar, Khorasan Razavi Province) is the product of alteration of dacitic rocks (Eocene) and is located in the Khaf-Kashmar-Bardaskan metallogenic belt. Field observations show that the development of this deposit was controlled by the tectonic system of the area and the presence of silica cap is the most important geological feature of this deposit. Mineralog...
متن کاملThe Behavior of Arsenic during the Thermal and Chemical Decomposition of the Ammonium–Arsenic Jarosite
Arsenic, an element of environmental impact, can be incorporated into jarosite–type compounds and remain stabilised within the structure under a wide range of environmental conditions. In this study, a sample of ammonium–arsenic jarosite was synthesised by precipitation in sulphate medium at controlled pH of 1.2–1.8. The behaviour of arsenic during the thermal and chemical decomposition of jaro...

متن کاملA study on the dissolution rates of K-Cr(VI)-jarosites: kinetic analysis and implications
BACKGROUND The presence of natural and industrial jarosite type-compounds in the environment could have important implications in the mobility of potentially toxic elements such as lead, mercury, arsenic, chromium, among others. Understanding the dissolution reactions of jarosite-type compounds is notably important for an environmental assessment (for water and soil), since some of these elemen...
