K. Klein, University of Toronto J. C. Santamarina, Georgia Institute of Technology The authors measured resistivity at various depths during the sedimentation of kaolinite in different ionic concentration fluids. They attributed a decreasing resistivity (increasing conductivity) with time in the low ionic concentration fluids to decreasing tortuosity. The authors suggested that the initial stru...

The major and trace element characteristics of the clinopyroxene from two generations dykes, dolerite olivine dykes Western Dharwar Craton were investigated by using electron microprobe LA–ICPMS. in show a compositional zoning with Mg# decreasing core to rim (85 51) Cr2O3 contents decrease towards rim. rare earth (REE) pattern shows lower concentrations REEs compared dolerites are devoid compos...

The effect of surface phonon scattering on the electrical resistivity has been observed in Co/Ni superlattices, with reproducible film microstructure, independent of the film thickness. The temperaturedependent part of the resistivity increases rapidly with decreasing film thickness for films thinner than the electronic mean free path. The resistivity shows a universal behavior well characteriz...

Diapirism has been discredited as a transport mechanism for magmas partly because diapirs seem to be unable to bring magmas to shallow crustal levels (< 10 km) and partly because recent developments in the theory of dyke propagation have shown that sufficiently wide dykes are able to efficiently transport felsic magmas through the crust. However, it is still unclear how felsic dykes grow to wid...
