Sulfate mineral | EPFL Graph Search

The sulfate minerals are a class of minerals that include the sulfate ion (SO42−) within their structure. The sulfate minerals occur commonly in primary evaporite depositional environments, as gangue minerals in hydrothermal veins and as secondary minerals in the oxidizing zone of sulfide mineral deposits. The chromate and manganate minerals have a similar structure and are often included with the sulfates in mineral classification systems. Sulfate minerals include: Anhydrous sulfates Barite BaSO4 Celestite SrSO4 Anglesite PbSO4 Anhydrite CaSO4 Hanksite Na22K(SO4)9(CO3)2Cl Hydroxide and hydrous sulfates Gypsum CaSO4·2H2O Chalcanthite CuSO4·5H2O Kieserite MgSO4·H2O Starkeyite MgSO4·4H2O Hexahydrite MgSO4·6H2O Epsomite MgSO4·7H2O Meridianiite MgSO4·11H2O Melanterite FeSO4·7H2O Antlerite Cu3SO4(OH)4 Brochantite Cu4SO4(OH)6 Alunite KAl3(SO4)2(OH)6 Jarosite KFe3(SO4)2(OH)6 IMA-CNMNC proposes a new hierarchical scheme (Mills et al., 2009).

The influence of water-saturation on the strength of volcanic rocks and the stability of lava domes

Marie Estelle Solange Violay, Michael Heap

The rocks forming a volcanic edifice or dome are typically saturated or partially-saturated with water. However, most experiments aimed at better understanding the mechanical behaviour of volcanic rocks have been performed on dry samples, and therefore mos ...

Selecting the best AOP for isoxazolyl penicillins degradation as a function of water characteristics: Effects of pH, chemical nature of additives and pollutant concentration

César Pulgarin, Paola Villegas Guzman

To provide new insights toward the selection of the most suitable AOP for isoxazolyl penicillins elimination, the degradation of dicloxacillin, a isoxazolyl penicillin model, was studied using different advanced oxidation processes (AOPs): ultrasound (US), ...
