Flow-path textures and mineralogy in tuffs of the unsaturated zone Flow-path textures and mineralogy in tuffs of the unsaturated zone

The high concentration of chlorine-36 (36Cl) produced by above-ground nuclear tests (bomb-pulse) provides a fortuitous tracer for infiltration during the last 50 years, and is used to detect fast flow in the unsaturated zone at Yucca Mountain, Nevada, a thick deposit of welded and nonwelded tuffs. Evidence of fast flow as much as 300 m into the mountain has been found in several zones in...

Geochemistry and hydromechanical interactions of fluids associated with the San Andreas fault system, California Geochemistry and hydromechanical interactions of fluids associated with the San Andreas fault system, California

18O values establish that waters are predominantly of meteoric origin. The chemical compositions of water and gases are controlled mainly by the ambient rock types, and chemical geothermometry gives reservoir temperatures of 80-150 degrees C indicating shallow to moderate circulation depths of up to 6 km. However, compositions and isotope abundances of noble gases and delta 13C values of...
