Definition of granophyre in English:

granophyre

noun ˈɡranə(ʊ)ˌfʌɪəˈɡranəˌfī(ə)r

mass nounGeology

A granitic rock consisting of intergrown feldspar and quartz crystals in a medium- to fine-grained groundmass.
〔地质〕花斑岩；文象斑岩
Example sentencesExamples
- Although the features described above are present everywhere in the partially melted gneiss, grain boundary films of fine granophyre also occur in about a third of the partially melted samples from Priomh-lochs.
- Some 600 m below this breccia the pluton is pervaded by a fine-grained granophyre, apparently the product of a sudden and final crystallization.
- The higher temperatures of the Fiachanis block and the general absence of fine granophyre suggest that this was subjected to longer and more intense heating than the gneiss at Priomh-lochs.
- Here, the 24-foot-thick bed strikes E-W, dips 25 [degrees] N., and is composed of subangular-to-rounded clasts composed of granophyre, rhyolite, and basalt.
- The Main Channel conglomerate is made up of a variety of well-rounded felsite, granophyre, and quartz-feldspar porphyry pebbles, suggesting a geologically diverse source terrane.

Geology

Sample CHA 3005 was taken from one of these rhyolite domes; it has miarolitic cavities and a conspicuous graphic and granophyric fabric.
Example sentencesExamples
- The rounded conglomerate pebbles consist of siltstone, mudstone, wacke, granophyric igneous rocks, and various intermediate to felsic volcanic rocks, set in a matrix rich in quartz and feldspar grains.
- Other fragments of igneous rock occur rarely and include granite (sometimes with granophyric texture), volcanic acidintermediate clasts with aphanitic texture and rounded fragments of silicified ash.
- Small intrusions of mafic diorite (the Northern Charnwood Diorites) and large intrusions of granophyric diorite (the Southern Charnwood Diorites or markfieldites) cut the bedded sequence.
- The first sign of melting in thin-section is the development of fine granophyric rims on grain boundaries between quartz and feldspar, interpreted to be solidified quartzo-feldspathic melt.

Origin

Late 19th century: from German Granophyr, from Granit 'granite'+ Porphyr (see porphyry).
