Mafic/ultramafic complex : eclogites/garnet pyroxenites/omphacite pyroxenites layered intrusion in UHP Dabieshan terrane.
Associated harzburgites.
Crustal layered intrusion (Proterozoic magma contaminated by meteoritic water) subducted along gneisses to mantle depth. It underwent UHP (depth > 100 km) metamorphism during China North/South blocks Triassic collision.
Contamination by upper crustal rocks during emplacement and differentiation.
