Differentiation of a lamprophyre sill
Differentiation trends in rock bodies of various sizes and types have been studied, from different viewpoints and with contrasting results, by many geologists in this country and abroad* Such studies are of major importance, ...
Nuclear magnetic resonance in single crystal lithium fluoride down to 1.5 degrees K
It has been proposed that the Li ions in crystalline LiF possess a lattice vibrational spectrum which differs from that of the F ions. With this in mind, the nuclear magnetic resonance absorption properties of LiF have ...
The experimental determination of K-values and activity coefficients by gas-liquid partition chromatography
A brief review of some important theoretical aspects of Gas-Liquid Partition Chromatography is presented, emphasizing in particular parameters connected with solution behavior. Preliminary to measurements conducted on light ...
Electrical properties of argon gas emerging from a plasma jet
Argon gas, which had been partly ionized by an electric arc with an enthalpy input in the order of 104 BTU/lbm was expanded through a supersonic wind tunnel nozzle. It was found to contain residual positive ions in excess ...
Textural properties of some source materials of clastic sediments
The purpose of this study has been to measure and describe the size distribution, shape, roundness, and mineralogic composition of sediments recently weathered from granite and at or very near their source, and to discuss ...
