In the Nuussuaq Basin, West Greenland, a thick succession of Tertiary dolerites has penetrated Upper Cretaceous mudstone. The mixed-layer minerals of mudstone core samples have been analyzed by X-ray diffraction, solid-state Si and Al magic-angle spinning nuclear magnetic resonance, Mössbauer and infrared spectroscopies, thermal analysis, chemical analysis, stable isotopes (O/O), and K/Ar dating.

16 p, 242.1 KB Smectite-illite-muscovite transformations, quartz dissolution, and silica release in shales / van de Kamp, Peter C.
Quantitative analysis of the smectite-to-elite and illite-to-muscovite transformations indicates that 17-28 wt. % SiO and 17-23 wt. % SiO, respectively, are liberated during these reactions, assuming that Al is conserved. [...]

11 p, 880.0 KB Mineralogy, geochemistry, and diagenesis of clinoptilolite tuffs (Miocene) in the central Simav graben, western Turkey / Snellings, Ruben (Catholic University of Leuven. Department of Earth and Environmental Sciences) ; van Haren, Tom (Catholic University of Leuven. Department of Earth and Environmental Sciences) ; Machiels, Lieven (Catholic University of Leuven.

Department of Earth and Environmental Sciences) ; Elsen, Jan (Catholic University of Leuven. Department of Earth and Environmental Sciences)
Miocene rifting and associated rhyolitic (K-rich) volcanism resulted in the deposition of pyroclastic material in the central Simav graben, near Karacaderbent, Turkey. The pyroclastics were deposited in a lacustrine environment, altered to clinoptilolite-rich tuffs and cross-cut by several transform faults along which hydrothermal fluids circulated. [...]

17 p, 2.0 MB Element distribution between coexisting authigenic mineral phases in argillic and zeolitic altered tephra, Olduvai Gorge, Tanzania / Mchenry, Lindsay. J. (University of Wisconsin-Milwaukee. Department of Geosciences)
The current study demonstrates how co-existing zeolite and clay minerals formed by the alteration of tephra in a closed-basin lacustrine and lake-margin environment can retain the overall composition of the original bulk tephra for many elements, even when diagenetic conditions and resulting authigenic mineral assemblages change. [...]
