... to SO 4 groups act as acceptor of H bonds from H 2 O groups coordinating Al atoms. The new data improved the description of the H bonds in khademite and led us to discuss about the possible existence of its (OH)-analogue, rostite. In addition, Raman spectroscopic data were collected on the same crystal...

... before thinning again closer to the confluence. These veins are composed of silica (typically opaline but occasionally with fine-grained quartz), sulfide (pyrite, marcasite, and trace galena, sphalerite), ASM (alunite, walthierite, huangite, rostite) with lesser native sulfur and uncommon barite. Breccia...

Numerous studies have shown that some aluminum hydroxysulfates play a vital role...

... jurbanite and rostite (1:1), which are well-crystallized and kept separate in Table 4b . These compositional changes must reflect the relative proportion of the dissolved Al to dissolved SO 4 (or sulfuric acid) in the aqueous solution, and, hence, the relative pH of the solution from which...
