Four thorium sulfate compounds have been synthesized and characterized. [Th(SO4)2(H2O)7] 2H2O (ThS1) crystallizes in space group P21/m, a1⁄47.2488(4), b1⁄412.1798(7), c1⁄48.0625(5) Å, b1⁄498.245(1); Na10[Th2(SO4)9(H2O)2] 3H2O (ThS2), Pna21, a1⁄417.842(2), b1⁄46.9317(8), c1⁄427.550(3) Å; Na2[Th2(SO4)5 (H2O)3] H2O (ThS3), C2/c, a1⁄416.639(2), b1⁄49.081(1), c1⁄425.078(3) Å, b1⁄4 95.322(2); [Th4(SO...

The Olympia Undae sand sea contains the largest known deposit of gypsum discovered on surface Mars. origin this gypsum, a hydrated sulfate mineral requiring liquid water for its formation, remains largely unconstrained. We examine hypothesis that was derived from early-Amazonian aged Basal Unit, which is suggested to contain sulfates. Previous attempts detect sulfates in Unit using CRISM and OM...

Among the first studies inspired by Cushny’s theory of renal function was the one undertaken by Mayrs, who investigated the excretion of sulfates as compared with the elimination of a number of other substances. He injected sodium sulfate intravenously into rabbits in order to raise the concentration of sulfate in the plasma to allow its determination with a sufficient degree of accuracy and fo...

Introduction: The gray crystalline hematite on Mars was detected in three regions, Sinus Meridiani, Aram Chaos and Valles Marineris by the thermal emission spectrometer (TES) onboard the Mars Global Surveyor (MGS) orbiter [e.g.1, 2]. The Mars Exploration Rover (MER) Opportunity confirmed that hematite-rich spherules (~ 4.2 mm) are embedded in sulfur-rich layered outcrops and accumulated on the ...
