Experimental observations of the effects of bacteria on aluminosilicate weathering
observations bacteria aluminosilicate weathering
2012/4/1
Mineral dissolution experiments using batch cultures of soil and groundwater bacteria were monitored with solution chemistry and various microscopic techniques to determine the effects of these organi...
Structural phase transition near 825 K in titanite: Evidence from infrared spectroscopic observations
Structural phase transition 825 K titanite Evidence infrared spectroscopic observations
2012/4/1
We report the direct experimental observation of a structural anomaly near 825 K insynthetic and natural titanite samples by high-temperature, hard-mode infrared spectros-copy. The anomaly in titanite...
Observations on the geometry of etched fission tracks in apatite: Implications for models of track revelation
Observations geometry of etched fission tracks apatite Implications track revelation
2012/4/9
TEispaperreports observations ofetched internal {OOO1}, {lOTO},{1120}, {loT1},and {1121} surfaces of Durango apatite. Three types of surfaces are distinguished: Ptype, S type, and T type. After initia...
TEM Observations of Coherent Stacking Relations in Smectite, I/S and Illite of Shales: Evidence for MacEwan Crystallites and Dominance of 2M1 Polytypism
2M1 Polytypism Coherent Fundamental Particles Illite I/S MacEwan Crystallites Optical Diffraction Patterns SAED Smectite Stacking Relations Cross Fringes
2011/12/23
Abstract: TEM characterization of stacking relations in I/S of expanded shale samples from the Gulf Coast and Michigan Basin was carried out to address the issues of the degree of coherency and the na...
Synthesis of high-pressure hydrous magnesium silicates: Observations and analysis
Synthesis of high-pressure hydrous magnesium silicates Observations analysis
2012/4/5
Specimens ofdense high-pressure hydrous magnesium silicates, notably phase A,phase B,and superhydrous phase B,have been synthesized for use in calorimetric and spectro-scopic experiments. X-ray diffra...
A Technique for Maintaining Texture and Permanent Expansion of Smectite Interlayers for TEM Observations
Illite LR White resin R1 I/S Rectorite Smectite Transmission electron microscopy (TEM)
2011/12/1
Abstract: A process for treating smectite-bearing rock samples that utilizes LR White resin; allows TEM observation of expanded smectite interlayers and therefore preservation of original rock texture...
Transmission Electron Microscope Observations of Illite Polytypism
Illite Polytypism Transmission electron microscopy
2012/1/4
Transmission electron microscopy (TEM), including selected area electron diffraction (SAED), has been used to identify polytypes in illite, phengite and muscovite from samples representing a wide rang...
Expansion of Smectite by Laurylamine Hydrochloride: Ambiguities in Transmission Electron Microscope Observations
Expansion Illite Lattice fringe images Laurylamine hydrochloride Smectite Transmission electron microscopy
2011/11/25
Abstract: Treatment of smectite with laurylamine hydrochloride was verified to cause expansion of d(001) which may be retained and observed in ion-milled samples by transmission electron microscopy. T...
Kaolinite Synthesis. I. Crystallization Conditions at Low Temperatures and Calculation of Thermodynamic Equilibria. Application to Laboratory and Field Observations
Aluminum Hydroxide Kaolinite Synthesis Thermodynamic
2012/2/10
The equilibrium diagrams developed for Al-hydroxide and for kaolinite by Garrels and Christ (1965) have been modified by taking into account the existence of gels. From the stability zones obtained, t...
Electron Optical Observations on Marblehead Illite
Electron Optical Observations Marblehead Illite
2012/2/15
Electron optical observations on Marblehead illite showed the presence of twinned aggregates of lath-shaped crystallites. The selected area diffraction patterns of these aggregates indicate a strict o...
