Hydrogeology of Volcanic Rocks
1999Volcanic rocks are formed by the solidification of magma at or near the ground surface. The most common volcanic rocks are basalts, which are of basic composition. Acidic and intermediate rock types such as rhyolites and andesites have comparatively very limited occurrences.

ABSTRACT Stylolites and microstylolites in a rhyolite from New South Wales are described and compared with those recorded by F. D. Bloss (1954) in a Newfoundland breccia. Factors promoting stylolite formation in lava may include differential devitrification, recrystallization and inversion of the silica minerals within siliceous bands, and deuteric ...
