Abstract: The matrix of the Pliocene volcaniclastics from the Akrotiri area of the Santorini island (Greece) is dominated by clinoptilolite. Smectite, occasionally illite-smectite, opal-CT, cristobali...
Abstract: The composition of clinoptilolite formed from volcanic glass was investigated from cuttings collected from the offshore MITI-Somaoki borehole, 52 km east of Soma City, Japan. Unaltered volca...
Abstract: Clinoptilolite and mordenite occur as diagenetic products of medium-grained, moderately welded and poorly sorted pyroclastic flows belonging to the Tertiary calc-alkaline volcanism of Sardin...
The solubilities of analcime and clinoptilolite were determined in dilute, weakly alkaline,aqueous solutions below 300 8 C and at vapor-saturated pressures. Analcimes used in this study were from Mont...
Abstract: Unmodified and surfactant-modified clinoptilolite-rich tuff (referred to here as 揷linoptilolite? and muscovite mica were examined with tapping-mode atomic force microscopy (TMAFM) and high-r...
Abstract: The enthalpy of hydration of natural clinoptilolite was determined by isothermal immersion calorimetry on Ca-, Na- and K-exchanged clinoptilolite (Fish Creek Mountains, Nevada). Heats of imm...
Abstract: Yucca Mountain, Nevada, is being investigated to determine its suitability to host a potential high-level radioactive waste respository. An important reason for its choice as a potential rep...
Variation of the NH4+-exchange and CO2-adsorption capacities with zeolite content was investigated in detail to assess the potential use of these capacities for the estimation of the zeolite contents ...
Athermodynamic formulation for the sorption ofH20in clinoptilolite hasbeen ob-tained from analysis ofequilibrium data collected bythermogravimetry on near end-memberCa-,Na-,and K-exchangednatural clin...
A cation-exchange capacity (CEC) method based on ion-sieving properties was developed for the quantitative determination of clinoptilolite in soils. In this method, both zeolitic and non-zeolitic exch...
Clinoptilolite from the Fort LaClede deposit in Sweetwater County, Wyoming, shows a moderate selectivity for NH4- over Na+ in aqueous solution. At 30°C, the standard free energy of this replacement re...
The mineralogy of partially kaolinized strata interbedded with lignite at the San Miguel mine, Atascosa County, Texas, was investigated by X-ray powder diffraction and optical and scanning electron mi...
To understand and predict the effects of a thermal pulse induced by a radioactive waste repository on clinoptilolite-bearing rocks, the lattice parameters of 6 natural and 3 cation-exchanged (Ca, K, N...
The identification and quantification of the water associated with powdered clinoptilolite and clinoptilolite-bearing tuffs were made using thermogravimetric, vacuum gravimetric, and differential scan...
