Origin of Igneous Rocks: The Isotopic Evidence
The origin of the Bushveld granophyres has been attributed to magmatic
differentiation, but Walraven (1985) demonstrated that several different types of
granophyre are present and that none of them formed by direct magmatic
differentiation ...

However, this would require that at least one-third of the Granophyre composition
be derived from shale, which contradicts mixing calculations of French and
Nielsen (1990), who only find a 10% shale contribution. All other relevant country

Geological Survey Professional Paper
Granophyre is common in some dikes. Both hornblende and biotite are generally
shredlike, but fine-grained aggregates of biotite or actinolite pseudomorphing
euhedral hornblende crystals are numerous. A little augite was seen in a thin ...

This dike was thought by Ransome to show remarkable variations in texture and
composition, ranging from a muscovite soda granite through soda syenite
granophyre to soda granite porphyry. But the exposures are poor, as Ransome
himself ...

Next, the road passes over low exposures of leucogranite (e.g., near NAD83
UTM 15T 0633349E; 5257618N), the uppermost, and main phase (frg) of the

crysts similar to those of the granophyre but have a glassy groundmass that
commonly shows flow banding; these are regarded as units of the Casto
volcanics. Although the granophyre is probably of Miocene age, none of these
intrusive ...

The granophyre cropping out south of the reentrant in the coastline at Duffs (Fig.
2) is an unusual facies of the Holyrood granite (Hughes, 1971). Intimately
associated with it is another facies of the granite unique to Duffs, namely,
pegmatite with ...

Mineralized Fracture Systems of the Skaergaard Intrusion, ...
1 1 illustrate two geometric types of mineralized fracture arrays associated with
the granophyre crack tips. In Fig. 1 IB the amphibole mineralized veins form
arrays subparallel to the granophyre that diverge with increasing distance from
the ...

Those without biotite resemble the fine-grained feldspathized qu.-irtzite (hybrid
granophyre) on Granite Mountain. In thin section the aplite dike in monzonite
resembles close]y the fine-grained Tertiary (?) granite in texture and composition.
