Geophagic Practices of the Setsing-Phuthaditjhaba Market Vendors in Thabo Mofutsanyane, Free State, South Africa.
Geophagic Soil Colour and Nematode Content in the District of Thabo Mofutsanyane, Free State, South Africa.
Palaeoenvironmental Characterisation Using Clay Mineralogy: A Case Study of the Heelbo hillslope deposit, Free State Province and the Diepdrift hillslope deposit, Limpopo Province, South Africa.
Abstract: Glauconite from the oxidized and reduced zones of soil-geologic columns at two Coastal Plain sites, one in Maryland and one in New Jersey, was examined by M鰏sbauer spectroscopy. The data ind...
The main objectives of this study were to describe the municipal solid waste management, leachate characteristics of China landfills, and to summarize the present research of leachate treatments in ch...
The deliberate consumption of soil/clay (geophagia) has been going on for centuries and cuts across socio-economic, ethnic, religious and racial divides. In countries with diverse ethnic origins, race...
Abstract: Silanol groups in protonated magadiite (H-magadiite) were characterized by 1H and 2H solid-state nuclear magnetic resonance (NMR). H-magadiite and deuterated (D) magadiite were synthesized b...
Abstract: Reduction of structural Fe in Na-exchanged dioctahedral smectites decreases swellability in water, but because clay interlayers also collapse in the process the concomitant effect on surface...
Crystal structures and phase transitions of enstatite (MgSiO ) were studied by in situ X-ray dif-fraction experiments using synchrotron radiation and a multi-anvil high-pressure apparatus at pres-/c t...
Proterozoic migmatites in the Black Hills, South Dakota, were examined to determine if parti- tioning of trace elements hosted by rock-forming minerals between melanosomes and leucosomes preserves r...
A new method to extract quantitative information from poorly resolved Si magic-angle spinning (MAS) nuclear magnetic resonance (NMR) spectra of natural mixed-layer illite-smectite (I-S) clays29Si i...
XANES measurements on gold-bearing arsenian pyrite from the Twin Creeks Carlin-type gold and Au and arsenic is present at As . Au is attributed deposits show that gold is present as both Au to su...
