glass
glass An amorphous,
metastable solid with the atomic structure of a
silicate liquid. Glass can be formed by
quenching a silicate
melt, the short time-scale for cooling or pressure reduction preventing the reorganization of the random liquid structure into an ordered crystalline structure. Since cohesion between atoms in the liquid silicate increases with increasing silica content, melts with high silicate contents are most likely to form glasses. Natural
igneous glasses of
rhyolite composition (70% SiO
2) are termed ‘obsidians’. A wide variety of glasses, formed by meteoritic impact into the lunar
regolith, exist on the lunar surface. Shapes include spheres averaging 100 μm in diameter, tear-drops, dumb-bells, etc., typical of rotational shapes assumed by splashed liquids. They do not resemble meteoritic
chondrules. Volcanic glasses, formed by
fire fountains during eruption of
mare basalts, also occur locally on the Moon. Their compositions match those of local surface rocks, soils, or minerals. No
tektite compositions are found.
