متن کاملEphemeral lakes and desert dust sources
[1] The processes that determine which areas are strong sources of mineral aerosols are not well known. In this study we consider the role of ephemeral lakes in modulating emissions of atmospheric mineral aerosols. We focus on two ephemeral lake regions that have been identified as source regions: the zone of Chotts in Tunisia and Algeria, and Etosha Pan in Namibia. Comparisons of satellite ret...

متن کاملNeutron Spectroscopic Study of Synthetic Alunite and Oxonium-substituted Alunite
Synthetic, polycrystalline samples of alunite [K0.88(H3O)0.12Al2.64(SO4)2(OH)4.92(H2O)1.08] and oxonium-substituted alunite [H3OAl2.87(SO4)2(OH)5.61(H2O)0.39] have been investigated using incoherent, inelastic neutron-scattering (IINS) methods in order to determine the nature of the non-OH “H2O”. IINS measurements were made on non-deuterated samples at 20 K using the HRMECS chopper spectrometer...
متن کاملAlunite supergroup: recommended nomenclature
Minamiite has been discredited and renamed natroalunite-2c to show a double unit-cell structure and natroalunite can be designated as natroalunite-1c to show a single unit-cell structure. Kintoreite can be designated as kintoreite-1c to show the same single unit-cell structure, and IMA 1993-039 is a new superstructure of kintoreite and can be designated as kintoreite-2c to show a double unit-ce...
