Age delimitation integrated with aeromagnetometric and aerogammaspectrometric survey advances the understanding of ophiolite evolution in Brasiliano Orogen. We focused on Bossoroca ophiolite, because oceanic crustal mantle rocks contain zircon metasomatic chloritite. A metadiorite a metavolcanoclastic rock were also studied to delimit relationship between island-arc infrastructure superstructur...
This study focuses on the petrographic and structural characteristics of geological formations Alépé region in Comoé basin. The characterization allows us to retain that area abounds a variety lithologies: amphibole metagranite, metadiorite, amphibolite metagrauwacke. lineament map attests was affected by polyphase tectonics (ductile brittle), all these deformations have NW-SE NNW-SSE; NW-ESE N...
East Salmas Metabasites, as one of the most extensive units of the metamorphic complex, is located in the northwest of Sanandaj-Sirjan zone. These metabasites are mainly composed of amphibolite and green shist, alternating with geniss, metadiorite and marble metamorphic rocks. Metabasites are structurally oriented and mass, and grain size varies from small to medium. According to microscopic st...
