Archean Greenstone Belts
Epidotization Besides occurring as a primary metamorphic phase, epidote occurs
in much the same way as carbonate. It often is found in fractures. As with
carbonization, epidotization appears to be primarily a post-metamorphic process.
2
Continental Reactivation and Reworking
There is no correlation of <5l80 values with the degree of epidotization and, as
discussed earlier, the low <*)ls0 values probably reflect the affects of contact
metamorphic fluid flow at 1.78 Ga. Minerals in the Napperby Gneiss and
pegmatites ...

Metasomatism and the Chemical Transformation of Rock: The ...
These conditions are typical of hydrothermal upflow zones, where different
metasomatic reactions can be observed, such as epidotization, chloritization,
sericitization, and silicification (Fig. 8.1). Epidotization – Epidosites are strongly ...

Geological Survey of Canada, Open File 2165
Epidotization of pillow cores involves large gains of CaO, oxidation of ferrous to
ferric iron and large losses of Na20. Chemical changes in zones of patchy
epidotization are similar to that displayed in epidotized pillow cores.

Low-Grade Metamorphism of Mafic Rocks
Field relations between epidosites, greenschist altered diabase, extension-
related faults, and gabbroic bodies indicate that epidotization within the Solea
graben occurred after at least some amagmatic (tectonic) extension of the crust ...

Geological Survey Professional Paper
Sherer (1969, 1972) concluded that the nephrite veins formed as a consequence
of hydrous metasomatic alteration of amphibolite with iron, aluminum, and
calcium being mobilized during this alteration to produce epidotization of the
country ...

The fact that many pseudomorphs are decidedly porous or are composed only in
part of epidote indicates that alumina may have been liberated at some places;
presumably this alumina was consumed at other centers of epidotization nearby,
...

United States Geological Survey Professional Paper
The epidotization of the brecciated porphyry has already been described. The
epidotization of the brecciated garnetite is well illustrated in Plate V, A, where the
angular fragments, bordered by epidote, are excellently shown; in the actual ...

Bulletin of the Geological Society of America
Lime metasomatism of hornblende may produce epidote (Gavelin, 1952, p. 27,
31), which appears as a granular alteration product along the cleavages of the
host mineral (Wooldridge, 1925, p. 243). Epidotization is to a certain extent
selective ...
