Sorption of uranium(VI) on Na-attapulgite as a function of contact time, solid content, pH, ionic strength, temperature and humic acid
Attapulgite U(VI) Sorption pH Ionic strength Temperature
2011/11/10
Sorption of U(VI) from aqueous solution to Na-attapulgite was investigated at different experimental chemistry conditions by using batch technique. The attapulgite sample was characterized by FTIR and...

contact metamorphism disequilibrium andalusite + melt stability P-T estimates Saraycı k granodiorite eastern Pontides Turkey
2009/7/7
The Eocene Saraycık granodiorite, eastern Pontides, Turkey, is a small post-tectonic intrusive body (~11 km2), cross-cutting tectonically juxtaposed distinct metamorphic and non-metamorphic litho...
IP measurements on tunnel walls of a sericite deposit—A contact method of nonpolarizable electrodes on a base rock and detection of clay minerals by normalized chargeability
IP (induced polarization) nonpolarizable electrode tunnel wall resistivity
2009/3/5
The development of the IP (induced polarization) measurement technique used inside a tunnel is required in order to estimate the subsurface resistivity and chargeability structures with high precision...
Surface Microtopography of Lath-Shaped Hydrothermal Illite by Tapping-Mode?and Contact-Mode AFM
Contact-Mode AFM Hydrothermal Illite Interlacing Pattern Microtopography Polytype Spiral Growth Tapping-Mode AFM
2011/12/8
Abstract: Lath-shaped hydrothermal illite particles in Izumiyama pottery stone were examined by contact-mode atomic force microscopy (CMAFM) and tapping-mode AFM (TMAFM) in air. With CMAFM, the lath-s...

Layer Silicates from Serpentinite-Pegmatite Contact (Wiry, Lower Silesia, Poland)
Chlorite Intergrade Mica SEM Serpentinite/pegmatite contact Three component interstratified minerals Vermiculite Weathering X-ray powder
2011/12/30
Highly tectonized contact between serpentinite and younger pegmatite in the magnesite mine of Wiry contains various layer silicates. Vermiculite, chlorite, smectite, and interstratified mica-vermiculi...
Surface Free Energy Components of Clay-Synthetic Humic Acid Complexes from Contact-Angle Measurements
Adsorption Aggregate stability Humic acid Montmoriltonite Surface free energy Wettability
2011/11/30
Abstract: The surface free energy components of clay-organic complexes were determined to assess to what extent an organic adsorbate modified the surface properties of the mineral, insofar as the stab...
Influence of Exchangeable Cations on the Surface Free Energy of Kaolinite as Determined from Contact Angles
Contact angle Dispersion Kaolinite Surface free energy Wettability
2012/1/5
The influence of adsorbed H+, Na+, K+, Ca2+, Mg2+, Ba2+, and Al3+ ions on the wettability of a kaolinite surface was determined from contact angles, which were measured in kaolinite-water drop- air (s...
K/Ar Systematics of Bentonite and Shale in a Contact Metamorphic Zone, Cerrillos, New Mexico
Age dating Bentonite Contact metamorphism Illite Illite/smectite K/Ar ages
2012/1/12
To test the ability of illitic clay minerals to retain argon, K/Ar ages were measured on grain-size separates from the Cretaceous Mancos Shale and associated bentonites that have been transformed into...
