South and East Asia represent one of the most tectonically active regions on Earth. The Pacific, Indo-Australia, and Eurasian plates converge around the Philippine Sea plate, resulting in a wide range of geologically and tectonically complex plate boundaries, including regions of both active and inactive oblique plate convergence. Many of these areas also preserve geologic evidence for subduction of oceanic and continental fragments to high, or ultrahigh pressures (i.e., mantle depths), raising fundamental questions about plate- and outcrop-scale processes. For example, does oblique convergence play a relatively unique role in the generation and/or preservation (i.e., subduction and exhumation) of high-pressure metamorphism? If so, are the accretion and exhumation flow paths truly 3D so plane strain may not apply? Finally, is there a characteristic signature in the rock record that can be used to identify past areas of oblique convergence? Here, we seek oral and poster presentations that bear on the accretion and exhumation processes along modern and ancient plate boundaries associated with either normal or oblique convergence. We also invite discussions of geodynamic models that integrate oblique convergence into a more holistic view of subduction, accretion, and exhumation. |
