Tile crystal structures of sjogrenite and pyroaurite, two stacking modifications of approximate composition Mg.Fe.(OH),.(CO.).4H.O, have been determined by X-ray diffraction using three-dimensional methods. Sjogrenite is hexagonal, with a 3,13, C 15.66 A, space group P6.!mmc, Z = !; pyroaurite is rhombohedral, with aH 3,13, CH 23.49 A, space group R3m or R3m, Z = i. Both structures are based on...

متن کاملMineralogical Characterization of Lunar Highland Soils
Introduction: It has been theorized that the effects of space weathering during soil formation on the Moon are similar to those for many other airless bodies (e.g., Vesta, Eros) [1,2]. Therefore, the study of these effects on lunar soils may form the basis for our understanding of other heavenly bodies. This is a particularly valid axiom for reflectance spectroscopy of these soils. It has been ...
