Needle twins and right-angled twins in minerals: Comparison between experiment and theory
Needle twins right-angled twins Comparison theory
2012/4/1
Transformation twinning in minerals forms isolated twin walls, intersecting twin walls with corner junctions, and wedge-shaped twins as elements of hierarchical patterns. When cut perpendicular to the...
Viscosity data for hydrous peraluminous granitic melts: Comparison with a metaluminous model
Viscosity data hydrous peraluminous granitic melts Comparison
2012/3/31
We performed 27 viscosity determinations on dry and water-bearing peraluminous hap-logranitic melts. The dry melt compositions cover the range of normative corundum to be expected in peraluminous gran...

Comparison of Hematite Coagulation by Charge Screening and Phosphate Adsorption: Differences in Aggregate Structure
Coagulation Kinetics Fractal Aggregate Hematite Light Scattering Phosphate Adsorption
2011/12/22
Abstract: The formation and structure of hematite aggregates were examined by dynamic and static light scattering techniques. A large range in coagulation kinetics was studied by varying either indiff...
Comparison of Structural Models of Mixed-Layer Illite/Smectite and Reaction Mechanisms of Smectite Illitization
Illite Illite/Smectite Mixed-Layer Reaction Mechanism Smectite
2011/12/22
Abstract: This paper compares mechanisms of the reaction of smectite to illite, in light of structural models for interstratified illite/smectite (I/S). The crystal structure of I/S has been described...
Comparison of the Mineralogical and Chemical Composition of 2 Shales from the Western Canada Sedimentary Basin and the United States Gulf Coast
Deposition Diagenesis Geochemistry Mineralogy Mixed-Layer Illite/Smectite Oxygen Isotopes
2011/12/9
Abstract: The mineralogy and geochemistry of shales reflect the composition of the initially deposited precursor mud, subsequently modified by diagenetic processes. To see if significant geochemical d...
