Metamorphic Rocks - Quiz No. 5 - Question 3
Symplectitic
Yes, that's correct.
This is a fine symplectitic intergrowth of diopside
and plagioclase, replacing sodic pyroxene (omphacite)
in an eclogite.
Part of the remaining omphacite is visible at the right.
The grain size of the intergrowth decreases towards the
omphacite, implying replacement during decreasing
temperature.
