Structural and spectroscopic studies of alkali-metal exchanged stilbites [PDF]
Abstract The structural, infrared (IR) and Raman spectroscopic properties of alkali-metal exchanged (Na+, K+, Rb+, Cs+) zeolites with the stilbite (STI) framework have been studied by Rietveld analysis of high-resolution synchrotron X-ray powder diffraction data, micro-Raman and synchrotron IR spectroscopy at ambient conditions.

Stilbite from bomeki, Miyagi Prefecture, Japan.
A calcium-rich stilbite occurs in the amygdaloidal cavity of the Upper Miocene dacite dyke at Bomeki, Miyagi Town, Miyagi Prefecture. Chemical analysis gave SiO2 56.38, Al2O3 15.89, CaO 7.94, Na2O 1.08, K2O.10, H2O+16.23 and H2O- 1.93wt%. Fe, Mn, Mg and P were not detected. This corresponds to Na1.00K.06Ca4.07Al8.96Si26.98O72•28.98H2O.

Amygdaloidal and other Cavity Filling Zeolites of Kuh-e-Aradeh, Central Iran [PDF]
Amygdaloidal, cavity- and fracture-filling zeolites in Eocene volcanic rocks from the Kuh-e-Aradeh of southern Kahrizak, in the northernmost part of Central Iran have been studied in some detail by optical, chemical analysis, SEM, and XRD techniques. The
