A note on the frictional strength of laumontite from Cajon Pass, California
Geophysical Research Letters, 1991 Laumontite mineralization is pervasive in joints and shear zones encountered in the Cajon Pass drillhole in southern California. In order to determine whether a gouge composed of this hydrated mineral affects shear strength in a manner similar to low‐strength, day‐rich fault gouges, frictional sliding experiments were performed under dry, saturated and

Bulletin of the Chemical Society of Ethiopia, 2002 Volcanic intrusions and hydrothermal activity have modified the diagenetic minerals. In the Ulster Basin, UK, most of the authigenic mineralization in the Permo-Triassic sandstones pre-dated tertiary volcanic intrusions.

Laumontite in an andesite from Kinzan, Satsuma-Cho, Kagoshima Prefecture.
The Journal of the Japanese Association of Mineralogists, Petrologists and Economic Geologists, 1979 A laumontite occurs in the cracks of an andesite at Kinzan, Satsuma-cho, Kagoshima Prefecture. Alkali content of the laumontite is higher than that of laumontites reported in Japan so far. Unit-cell constants calculated from x-ray powder data are very close to those of reported laumontites; a=14.765±0.007A, b=13.135±0.005A, c=7.561±0.004A and β=111.766±

Influence of Temperature on the Microstructure Deterioration of Sandstone
Energies, 2018 Macroscopic properties of sandstone are commonly attributed to the degradation of its microstructure during heating treatment processes. However, few previous studies have focused on comprehensive observations on how the microstructure of sandstone ...
