An atomistic computer simulation study was undertaken to address the role of Al in the substitution of ferric iron into magnesium silicate perovskite, MgSiO 3. Calculated substi-tution and vacancy en...
We present a new oxybarometer for magnesiowu¨stite-bearing systems, which is easily applied using widely available techniques. A scale relating the proportion of Fe31[a5Fe31/(Fe311 Fe21)] to the posit...
Sanidine crystals precipitating from lamproitic magmascharacteristically contain ap-preciableamounts ofFeH. Sanidinegrainsfrom the LeuciteHillslamproites (Wyoming) have compositions in whichupto 70mol...
The role of adsorbed and structural Fe3+ in palygorskite and sepiolite with respect to the oxidation of hydrocortisone in aqueous suspension has been evaluated using electron spin resonance and UV-vis...
Deferration by reduction of free Fe2O3 with Na2S2O4 in the presence of Na citrate and NaHCO3 caused a change in valence state of 10 to 35 per cent of the total structural iron in micaceous vermiculite...
