Granophyre - Wikipedia
Granophyre (/ ˈ ɡ r æ n ə f aɪər / GRAN-ə-fire; [1] [2] from granite and porphyry) is a subvolcanic rock that contains quartz and alkali feldspar in characteristic angular intergrowths such as those in the accompanying image. The texture is called granophyric.
Granophyre | Igneous Rock, Intrusive Rock, Plutonic Rock
Granophyre, fine-grained igneous rock that is characterized by a porphyritic texture, having large crystals (phenocrysts) that rest in a nonglassy, finely crystalline matrix (groundmass). Granophyre is similar to granite, except for its fine texture and smaller grain size; those granophyres that.
Granophyre - an overview | ScienceDirect Topics
Granophyre is a type of rock that is occasionally present in granitoids, characterized by a fine-grained texture and composed of plagioclase, K-feldspar, quartz, biotite, and minor accessory minerals like magnetite, zircon, and apatite.
Granophyre - ALEX STREKEISEN
Granophyres typically are intrusive rocks that crystallized at shallow depths, and many have compositions similar to those of granites. A common occurrence of granophyre is within layered igneous intrusions dominated by rocks with compositions like that of gabbro.
Granophyre - SpringerLink
A granophyre is a felsic, holocrystalline, intrusive or extrusive rock in which quartz and feldspar are abundant and intimately intergrown micrographically in a regular or irregular manner. This type of texture is known as granophyric (Fig. 1; Johannsen, 1939).
