Ultramafic xenoliths in Cenozoic alkali basalts from Yitong, northeast China comprise three types in terms of their modal mineralogy: lherzolite, pyroxenite and wehrlite. The wehrlite suite always contains interstitial pale/brown glass which occupies

The Xigaze ophiolite, (Tibet) displays unusual lithological, petrological, textural, and structural characteristics. There are no large masses of cumulate gabbros, but dolerite intrusives throughout the whole ophiolite sequence, some of which were in

The Xigaze ophiolite (Southern Tibet) exhibits an unusual ophiolite sequence characterized by: 1. (1) the limited thickness (less than 3 km) of its crustal unit which is mostly composed of dolerite intrusives, the gabbros being very scarce; 2. (2) th

The bulk compositions of coexisting enstatite and diopside in basal lherzolites and clinopyroxene-bearing harzburgites from ophiolitic complexes are typical of solidus/subsolidus equilibria, but for a few texturally distinct “magmatic” diopsides.

Three massifs in the Xigaze area (Southern Tibet, China), have been preserved from the intense deformation observed everywhere else in the Yarlung Zangbo Suture Zone. These massifs have similar lithologies and display a remarkable homogeneity in the

The available experimental data on garnet-bearing-assemblages for synthetic chemical systems (MAS, FMAS, CMAS) have been used to calibrate consistent models for the Al-solubility in orthopyroxene coexisting with garnet, on the basis of equilibrium re

Many of the peridotite xenoliths included in the San Quintin (Baja California Norte, Mexico) quaternary alkali-basalts have undergone a very intense shear deformation (deviatoric stresses up to 0.1 GPa), hence a first-order classification into coarse
