U.S. Geological Survey professional paper
It has a well- defined eutaxitic structure, and flattened pumice fragments are as
long as 2 feet. Phenocrysts of quartz and feldspar make up 5 to 10 percent of
typical specimens (table 2, columns 12-22) ; hornblende is commonly present in
trace ...

Geological Survey Professional Paper
Certain terms used in describing the structural and textural features of the ash-
flow tuffs, such as "fluidal," "eutaxitic," and "vitroclastic," are better understood
from photographs than from words. Fluidal structure in a hand specimen is
illustrated ...

It grades upward from an incompletely welded clast-rich tuff, to a phenocryst-poor
, pumice-rich tuff with fluidal eutaxitic structure (Fig. 5). Felsitic fragments range in
diameter from 1 to 9 cm. The pumice fragments near the base of the zone are ...

welded tuff containing intratclluric crystals or phenocrysts which giv(- it the
appearance of porphyritic flow rock. In thin section the rock has a eutaxitic
structure which may be obscured locally where crystallization has been intense.
This zone is ...

Eutaxitic, rheomorphic and lava-like lithofacies (e.g. emLT; edbLT; rheomLT; lava
-likeT) Description Some massive and bedded lithofacies of ignimbrites possess
a eutaxitic fabric of deformed juvenile pyroclasts, for example fiamme and ...

4a-c). These structures are abundant in the inner (Slievebrack) rhyolite body, but
rare or absent in the outer (Carrive) rhyolite body (Emeleus 1962). 1n three
dimensions, these structures define a planar (eutaxitic) fabric measurable in
outcrop.

These veins, however, clearly partly predate the eutaxitic foliation because where
they cut the uncollapsed pumice plates, they are almost planar; whereas in the
eutaxitic matrix, they are ptygmatically folded. This is in direct contrast to ...
