Title

MINERALOGY – PETROFABRIC OF GHORVEH METAMORPHIC COMPLEX (NW OF IRAN)

Pages

  203-220

Abstract

 Introduction: The GHORVEH METAMORPHIC COMPLEX consists of regional and contact metamorphic rocks. The regional metamorphic rocks are including meta-sediments and metalimestone and are related to green schist to amphibolite facies.Aim: The contact metamorphic series are schist, marbls and quartzite and are inferred to result from hornblend to pyroxene hornfels facies.Methods: Studying of oriented thinsection using of universal stage.Results: The LPO Patterns of quartz in regional metamorphic schists show BASAL SLIP SYSTEM along a<a>direction that confirms the green schist facies condition. The pattern of c- axes distributions of quartz in the marbles reveals a basal and RHOMB SLIP SYSTEM along a<a>direction that are consistent with green schist to lower amphibolite facies.Conclusions: According to microstructural studies two discrete DEFORMATIONal events are recorded in Ghorveh metamorphic rocks. The first DEFORMATIONal phase (D1) forms a first schistosity (S1) and inter-tectonic staurolite and garnet porphyroblasts. The second phase of DEFORMATION (D2) as a S2 fabric followed by syn to post-tectonic andalusite, sillimanite and cordierite porphyroblasts. In the last stage, the retrograde metamorphic events are created from emplacement of metamorphic rocks. As result, the proposed P-T-t path indicates a clockwise path with maximum temperature 700oc and maximum pressure 4 Kbar for GHORVEH METAMORPHIC COMPLEX.
