syenitic gneiss
(gcide) | Gneiss \Gneiss\ (n[imac]s), n. [G.] (Geol.)
A crystalline rock, consisting, like granite, of quartz,
feldspar, and mica, but having these materials, especially
the mica, arranged in planes, so that it breaks rather easily
into coarse slabs or flags. Hornblende sometimes takes the
place of the mica, and it is then called hornblendic gneiss
or syenitic gneiss. Similar varieties of related rocks are
also called gneiss.

Syenitic granite
(gcide) | Granite \Gran"ite\ (gr[a^]n"[i^]t), n. [It. granito granite,
adj., grainy, p. p. of granire to make grainy, fr. L. granum
grain; cf. F. granit. See Grain.] (Geol.)
A crystalline, granular rock, consisting of quartz, feldspar,
and mica, and usually of a whitish, grayish, or flesh-red
color. It differs from gneiss in not having the mica in
planes, and therefore in being destitute of a schistose
structure.
[1913 Webster]
Note: Varieties containing hornblende are common. See also
the Note under Mica.
[1913 Webster]
Gneissoid granite, granite in which the mica has traces of

replacing the mica.
