英文摘要 | The Feiran-Solaf metamorphic complex of Sinai, Egypt, is one of the highest grade metamorphic complexes of a series of basement domes that crop out throughout the Arabian-Nubian Shield. In the Eastern Desert of Egypt these basement domes have been interpreted as metamorphic core complexes exhumed in extensional settings. For the Feiran-Solaf complex an interpretation of the exhumation mechanism is difficult to obtain with structural arguments as all of its margins are obliterated by post-tectonic granites. Here, metamorphic methods are used to investigate its tectonic history and show that the complex was characterized by a single metamorphic cycle experiencing peak metamorphism at similar to 700-750 degrees C and 7-8 kbar and subsequent isothermal decompression to similar to 4-5 kbar, followed by near isobaric cooling to 450 degrees C. Correlation of this metamorphic evolution with the deformation history shows that peak metamorphism occurred prior to the compressive deformation phase D(2), while the compressive D(2) and D(3) deformation occurred during the near isothermal decompression phase of the P-T loop. We interpret the concurrence of decompression of the P-T path and compression by structural shortening as evidence for the Najd fault system exhuming the complex in an oblique transpressive regime. However, final exhumation from similar to 15 km depth must have occurred due to an unrelated mechanism. |
