Amphibole – in these rocks – exists in garnet amphibole and amphibole schist with different fabrics that consists of oriented nematoblastic, shearing, cataclastic, acicular amphibole needles with central assemblage and cross growth, along to the C-axis. The state of the central assemblage and the cross growth of amphibole minerals related to grain boundary diffusion creep processes and simultaneous metamorphic process that is so-called Garbenschiefer texture. Garbenschiefer texture in the Soursat Complex is made up by shearing and large–scale folding and simultaneous regional metamorphism, and also in the Khajoo zone related to shearing of strike–slip faults and simultaneous regional metamorphism. Mineral chemistry of amphibole in garnet amphiboles is in the range of ferro–hornblende to ferro–tschermakite hornblende and also the schist amphiboles with different minerals and different fabrics is in the range of magnesio–ferro hornblende to tschermakite–ferro-tschermakite hornblende. The reason for chemical differences between amphibole mineral in garnet amphiboles and amphibole schists are due to variation between their protolits. There is no significant relationship between different fabrics and chemistry of amphibole minerals.
