Pressure-induced migration of zeolitic water in laumontite
Physics and Chemistry of Minerals, 2004 A polycrystalline sample of natural laumontite (Pleasant Valley, Connecticut) was studied up to 6.8 (1) GPa at room temperature using monochromatic synchrotron X-ray powder diffraction and a diamond-anvil cell. A methanol: ethanol: water mixture was used as a penetrating pressure-transmitting fluid.

Hydrothermal synthesis of laumontite, a zeolite
Microporous and Mesoporous Materials, 1998Abstract Laumontite was synthesized in a wide temperature range (between 30°C and 450°C) by hydrothermal treatment of artificial glasses of composition 1CaO–1Al 2 O 3 –4SiO 2 at 1 kbar H 2 O pressure. The zeolite was always formed with monoclinic symmetry ( C 2/ m , a =15.02 A, b =13.15 A and c =7.71 A, β =113°).

Dehydration-hydration reactivity of laumontite: analyses and tests for easy detection
Clay Minerals, 2017 AbstractHydration reactions are known to affect rock or aggregate stability in construction; laumontite is not usually considered to be a ‘problem-mineral’ though drill cores from the very low-grade metamorphic altered andesites and volcanoclastic rocks from Central Chile showed detachments of shotcrete in a tunnel exposed to periodic water flow, with ...
