| 英文摘要 | The Saih Hatat Dome in the Al Hajar Mountains provides an outstanding opportunity to study subduction/exhumation processes coeval with obduction of the Semail Ophiolite. The exceptionally good outcrop conditions offer a unique opportunity to constrain the geometry of this subduction/obduction complex. In this review, the metamorphic, structural, and tectonic evolution of the Oman high-pressure complex in the Saih Hatat Dome is discussed. New structural cross-sections are developed and are used to interpret a geometrically feasible tectonic model for the Saih Hatat Dome. Our review highlights the importance of two major tectonic boundaries: (1) The As Sheik Shear Zone which separates the high pressure rocks of the As Sifah Unit (1.7-2.3 GPa and 510-550 degrees C) from the overlying Hulw Unit (1.0-1.2 GPa and 250-300 degrees C), and was active at similar to 79-76 Ma; and (2) the Upper Plate-Lower Plate Discontinuity, which forms a major surface in the landscape and developed by similar to 76-74 Ma, cutting through structures of the HP rocks in the lower plate (footwall). This discontinuity is associated with a pronounced strain gradient, notably in its upper plate (hanging wall), and separates rocks that have markedly different deformation geometry. The Upper Plate-Lower Plate Discontinuity initiated with a modest dip angle, making it a neutral structure in terms of crustal shortening vs extension. As a result, there is no discernable break in P-T conditions across it. The upper plate is dominated by the Saih Hatat Fold Nappe, forming between similar to 76 and 70 Ma. Subsequently, the upper plate has been dissected by a number of NNEdipping thrusts at similar to 70-66 Ma, followed by normal faults at |
