High-pressure Metamorphism

Metamorphism in subduction zones. Characteristic minerals and assemblages of the blueschist and eclogite facies. Transformations, and evidence for the P-T-time evolution of high-pressure rocks.

Eclogite petrography

A set of thin section images, all at the same scale (1.5 x 1 cm) showing the range of textures to be found in metabasic eclogites from several different terranes, plus a few other associated high-pressure rock types.
