Abstract

Abstract

Jadeite-quartzite of Dabie Mountains is one of the important rock types occurring in ultrahigh-pressure (UHP) metamorphic belts. It is significant to study the jadeite-quartzite's deformation mechanisms and geodynamical parameters (such as stress, strain, strain rate) for the knowledge on the formation and evolution of the Dabie-Sulu ultrahigh-pressure (UHP) metamorphic belts. Three representative samples of the Shuanghe jadeite-quartzite from Dabie UHP belt were undertook by the microfabric and TEM for lattice preferred orientation (LPO). The results show that the LPOs of jadeite are similar to those of omphacite. Their LPOs are L- and LS-type. However, the LPOs of quartze are monoclinic symmetry type. The slip systems of jadeite are mainly (100), (110) and (110) 1/2. Abundant dislocations develop in quartz, which is of dominant slip system of (0001) -derived from basal glide. The slip system represented regional shearing durin g the exhumation of the UHP belt.
