The non-differentiated matter or base of the groundmass not infrequently
assumes a microfelsitic or cryptocrystalline character. To the unassisted eye this
substance seems to be quite compact and homogeneous ; but under the
microscope ...

Proceedings of the Boston Society of Natural History
By polarized light the base is found to be completely devitrified, giving rise to the
so-called micrOfelsitic base. The flow texture of the rock, followed by its sudden
chilling, probably arose from the magma being SO siliceous. In the subsequent ...

Microfelsitic. This term is applied to a substance which in some respects closely
resembles vitreous matter, but differs from it in being less translucent and in
consisting of hazily-defined scales and fibres. When these are irregularly
disposed the ...

Under the microscope it is seen to consist of rounded and broken fragments of
quartz and felspar in a greenish microfelsitic base showing flow-structure and, in
parts, indications of perlitic structure. 3. Boad from Miandab to Sujbulak. Rhyolitic

Geological Survey professional paper
The groundmass varies greatly; in some specimens it is spherulitic, in others
microfelsitic, micro- granular, micropegmatitic, or glassy. It is made up chiefly of
quartz and alkalic feldspar. The associated darker quartz latites differ from those
just ...

One of them contains more fragments of the acidic magmatic rocks with
microfelsitic and microhipidiomorphic structures, as well as tuffs (7) or tuffites,
probably of pyroclastic origin. Other sandstones contain many fragments of
magmatic rocks, ...
