Disilicates and Ring Silicates
The formation of epidote as reaction rims between garnet and clinopyroxene with
plagioclase in the calc-silicate granulites of the Furna complex, southern
Tanzania, has been described by Coolen (1980). The rims around garnet consist
of an ...

Field Guide to Rocks & Minerals of Southern Africa
Epidote ranges from transparent (in thin crystals) to opaque (in larger crystals).
Most common habits are smooth, striated, elongated and prismatic, but can also
be needle-like clusters and fibrous hair-like groups or massive lumps in igneous
...

The Book of Stones: Who They Are and What They Teach
inundated with negativity, within and without, it soon becomes unbearable, or at
least unavoidably visible, and one is nudged forcefully into change. This sort of
dynamic happens frequently in the outer world, even without the help of Epidote.

Understanding Granites: Integrating New and Classical Techniques
Petrographically, the more mafic rocks are tonalitic in composition and fine-
grained with micro-porphyritic texture due to the presence of epidote, titanite and
some plagioclase pheno- crysts. The partially recrystallized mesostasis is almost
...

Alhitised Andesite Albitised andesites are the chilled contact rocks of the diorites
in the Ataata Point area. They are dark, fine-grained, compact, porphyritic rocks
crossed by many light yellow epidote-albite veins up to 9 in. across. Specific ...

At temperatures less than the stability limit of epidote (i.e., 150-250°C at P = 0.5-
2.0 kbar) pumpellyite with high Fe3' may crystallise directly instead of epidote
from highly oxidised, palagonitised basaltic glass (cf. Tomasson &
Kristmannsdottir ...
