The Role of Clay on Soil Erosion and its Implications on Agriculture: A Review.
A thick sequence of largely undeformed red-bed sandstones of Mesoproterozoic age, collectively termed the Pandurra Formation, overlies a wide area of crystalline basement of the central and eastern Ga...
Climate change-related legislation and regulation have the potential to impose substantial burdens on the lime industry in the United States and elsewhere. Over the last fifteen years, the U.S. gover...
Abstract: Thermal maturity of the Lower Cretaceous Sindong and Hayang groups in the Gyeongsang Basin, Korea, was investigated using the Kübler illite “crystallinity” index (KI) which is based on the n...
Abstract: Area-weighted thickness distributions of fundamental illite particles for samples of illite and illite-smectite from seven locations (including bentonites and hydrothermally altered pyroclas...
Abstract: Otay-type waxy bentonites of San Diego County are illite-smectite (I-S) with 85% dioctahedral smectite mixed with dioctahedral illite showing a Reichweite of 0. Primary or secondary waxy ben...
STM images of hematite (?-Fe O ) (001) surfaces taken under a wider variety of conditions than in previous studies are presented. The results strongly suggest that only Fe sites contribute to the tun...
Abstract: The residual kaolin deposits near Lastarria, South-Central Chile, were formed by weathering of subvolcanic quartz porphyry stocks, which intruded the metamorphic basement of the Coastal Cord...

Soluble proteins in the scallop ( Patinopecten yessoensis ) foliated calcite shell layer were characterized using biochemical and molecular biological techniques. SDS PAGE of these molecules revealed ...
Abstract: Oxygen isotopic compositions were determined for coexisting mixed-layer serpentine-chlorite (Sp-Ch) and illite-smectite (I-S) from 5 Tuscaloosa Formation sandstone cores sampled between 1937...
The reaction talc 1 forsterite 5 enstatite 1 H2O has been investigated between 6 and 20 kbar. Previous high-pressure experimental studies suggested various reaction positions,mostly with positive P - ...
A new spinelloid polytype with a composition Fe2.45Si0.55O4 has been synthesized at 1100 8C and 5.6 GPa that is isostructural with wadsleyite [b2(Mg,Fe)2SiO4 ]. The refined param-eters (space group I...
