Some mafic parts exist, they also have greenschist assemblages of actinolite, plagioclase and sometimes epidote or clinozoisite.
22.
A contact aureole of 2.5 km thickness surrounds the batholith in the form of albite epidote hornfels.
23.
Typical skarn minerals include pyroxene, garnet, idocrase, wollastonite, actinolite, magnetite or hematite, and epidote.
24.
The rock is foliated dark green rock containing chlorite, epidote, quartz, calcite, biotite, albite and actinolite.
25.
Giuc studied the granitic rocks of the Pricopan Ridge in Northern Dobruja, arguing for a magmatic origin of the epidote.
26.
I was wondering, and looked everywhere for that matter, the odds of finding gem quality Epidote in the united states.
27.
Older materials can be dated using zircon, apatite, titanite, epidote and garnet which have a variable amount of uranium content.
28.
The rock is derived from basalt, gabbro or similar rocks containing sodium-rich plagioclase feldspar, chlorite, epidote and quartz.
29.
These are known as greenstone belts, because low-grade metamorphism of basalt produces chlorite, actinolite, epidote and other green minerals.
30.
The dominant green epidote in unakite rocks is the metasomatic alteration product of plagioclase feldspar, while the orthoclase and quartz crystals remain unaffected.
