Volcanic Ash Soils: Genesis, Properties and Utilization
Classification of volcanic glasses Volcanic glass may be viewed as a metastable
supercooled liquid which results from a reduction in nucleation and crystallization
rates due to the rapid cooling of the magma. The chemical composition of ...
S. Shoji, M. Nanzyo, R.A. Dahlgren, 1994
High porosity and surface area of the fine-grained material also accelerate
diagenesis and promote devitrification of volcanic glass. Except where preserved
in a "sealed environment," glass is commonly found only in mid-Tertiary and
younger ...
