... shadowy double refraction characteristic of the devitrification of siliceous
glasses into obscure aggregates of quartz and feldspar. But distinct well-formed
crystals of younger growth than the evidently intratelluric phenocrysts do not
occur.

But this process is likely to yield some recognizable reentrant cavities, analogous
to the corroded phenocrysts of intratelluric quartz commonly present in rhyolite
porphyry. VARIATIONS IN PHYSICAL PROPERTIES Variations in the color, size,
...

Progress in Metamorphic and Magmatic Petrology: A Memorial ...
In effusive and subvolcanic rocks, the early stage of magmatic crystallization is
represented by phenocrysts known as intratelluric (deep-seated). They consist
predominantly of minerals which form under high lithostatic pressure such as
garnet, ...

The intratelluric alteration, following partial resorption, and the subsequent
growth of fresh olivine in optical continuity with that of the core is displayed by the
phenocrysts in the transitional tholeiitic to alkalic flows and dykes of the East
Molokai ...

However, among the intratelluric phenocrysts there often appear minerals which
correspond to the higher members of the reaction nucleus. For example, olivine
insets are not infrequently encountered in gabbro -porphyrites; in granite ...

This fact can be explained by the additional injection of less fractionated magma
portions into the chamber, with this magma likely containing intratelluric
orthopyroxene of a lower degree of fractionation than that of the orthopyroxene ...

Intratelluric Rgeonites. While the writer's view of 1932 was constatent, on the
whole, with the facte then known of igneous pyroxenes, one fact was puzzling:
that there occur, in some cases, porphyritic (intratelluric) pigennites, as, for
example, ...

It is possible that the intratelluric crystallisation of kaersutite, a common phase in
the more potassic, intermediate lavas of the Dunedin district -Benson 1939;
Coombs & Wilkinson 1969) has played some part in the evolution of the trachyte.

However, complex intergrowths of plagioclase and pyroxene (rarely olivine)
found in some of the flows are probably glomerophyric clots indicative of
intratelluric crystallization. A few plagioclase crystals have corroded core zones,
and some ...

This rock contains also metallic iron of intratelluric origin. petrogenetic point of
view; but the latter have a significance which demands some further
consideration. On general grounds it seems evident that crystallization (often
followed by ...
