Mass transport in vitric tuffs of Rainier Mesa, Nye County, Nevada

Technical Report ·
OSTI ID:7294348

Chemical and physical analyses of reactant and product phases found in subaerially-exposed vitric tuffs of Rainier Mesa, Nevada, indicate that diagenetic alteration is occurring today. Variations in the composition of the fluid phase with depth suggest a predominantly vertical transport process whereby the dissolution of metastable glass drives the sequential precipitation of montmorillonite, clinoptilolite and possibly analcime. Mordenite was found to exhibit a patchy occurrence within the clinoptilolite zone.
