Regional metamorphism has converted the shale to a low greenschist facies, where clay is converted to chlorite.
22.
The sedimentary rocks that were laid down in the basin are often weakly metamorphic ( greenschist facies ).
23.
Some mafic parts exist, they also have greenschist assemblages of actinolite, plagioclase and sometimes epidote or clinozoisite.
24.
When Cormoran fell asleep from exhaustion, his wife tried to sneak a greenschist slab from a shorter distance away.
25.
The metapelites are of granulite facies and the ultramafics are of greenschist facies and the enclosing gneisses represent amphibolites facies.
26.
It occurs metamorphic rocks of the greenschist to amphibolite metamorphic facies and in low-temperature hydrothermal veins in altered volcanic rocks.
27.
The Yuli Schist is Cretaceous in age and consists of black schist and some greenschist, glaucophane schist, and spotted slate.
28.
During the time of the Mississippian culture, the polity of Moundville apparently had some control over the production and distribution of greenschist.
29.
Illite crystallinity can be used to trace the low grade metamorphic transition from zeolite facies to greenschist facies ( diagenetic zone to epizone ).
30.
It is often found in minute micaceous aggregates ( with individual plates barely visible ), as a major component of chromium rich greenschist facies.
