Rock Samples Indicate Water is Key Ingredient for Crust Formation
Rock Samples Indicate Water Crust Formation
2017/7/19
By examining the cooling rate of rocks that formed more than 10 miles beneath the Earth’s surface, scientists led by The University of Texas at Austin Jackson School of Geosciences have found that wat...
The electrical signature of rock samples exposed to hydrostatic and triaxial pressures
Electrical impedance spectroscopy fracturing carbonate amphibolite pressure
2015/9/28
The electrical signature of sedimentary (carbonate) and crystalline rock samples was studied in hydrostatic and triaxial pressure experiments up to 300 MPa. The aim was to establish a relation between...
The spectrum of thermally stimulated currents in rock samples from KTB drilling:preliminary results
thermally stimulated depolarization currents (TSDC) KTB drilling rocks relation parameters
2015/9/28
The technique of thermally stimulated depolarization currents (TSDC) was applied to fine grained amphibolite rock samples extracted from KTB drilling. Each sample was cooled down to liquid nitrogen te...
Simultaneous determinations of fluorine, chlorine, and sulfur in rock samples by ion chromatography combined with pyrohydrolysis
pyrohydrolysis halogen sulfur ion chromatography geological reference material
2017/4/10
We present a simplified method for simultaneous determinations of fluorine (F), chlorine (Cl), and sulfur (S) contents
and isotopic abundances in rock samples. After using pyrohydrolysis to extract F...
The correlation of electrical charge with strain on stressed rock samples
correlation electrical charge strain stressed rock samples
2010/1/4
Laboratory experiments on rock samples have shown electric signal emissions when the samples are subjected to temporal stress increase especially when the samples approach failure. These electric sign...
Streaming potential measurements 1. Properties of the electrical double layer from crushed rock samples
Streaming potential measurements Properties of the electrical double layer crushed rock samples
2014/4/15
Thezpotential has been inferred from streaming potential measurements with crushed rock samples as a function of pH and electrolyte concentration for various salts. The value obtained for crushed Font...
Streaming potential measurements 2. Relationship between electrical and hydraulic flow patterns from rock samples during deformation
Streaming potential measurements 2. Relationship between electrical hydraulic flow patterns rock samples during deformation
2014/4/15
Streaming potential and resistivity measurements have been performed on Fontainebleau sandstone and Villejust quartzite samples in a triaxial device during compaction, uniaxial compression, and ruptur...
