These studies build on the pioneering work of USGS geologists George Plafker, Don Miller, Don Richter, and others. In this talk, I will focus mainly on the sedimentary record of Cenozoic flat slab subduction processes in southern Alaska. We will first discuss the sedimentary strata that were deposited directly on the Yakutat oceanic plateau that forms the lower plate of the convergent boundary. The lower plate strata archive the record of initial collision farther to the south, strike-slip transport along the Cordilleran margin, and ongoing subduction of the oceanic plateau beneath Alaska. Large parts of the lower plate strata have been incorporated into the upper plate of the southern Alaska convergent margin along the active collisional zone. We will then discuss the record of flat slab subduction processes on the upper plate of the southern Alaska convergent boundary. Flat slab subduction has had a profound impact on the formation and exhumation of sedimentary basins, the locations of volcanic arc systems, and the generation of the highest topography in North America. I will end the talk by briefly discussing ongoing collaborative research projects in the northern Cordillera.", "occurrence_notes":null, "guid":"153907-21916623@events.umich.edu", "permalink":"http:\/\/events.umich.edu\/event\/153907", "building_id":"1000188", "building_name":"1100 North University Building", "campus_maps_id":"628", "room":"1528", "location_name":"1100 North University Building", "has_livestream":0, "cost":"", "tags":["Earth And Environmental Sciences"], "website":"", "sponsors":[ { "group_name":"Earth and Environmental Sciences", "group_id":"3170", "website":"http:\/\/www.lsa.umich.edu\/earth" } ], "image_url":"https:\/\/events.umich.edu\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "styled_images":{ "event_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_thumb\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_large":"https:\/\/events.umich.edu\/media\/cache\/event_large\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_large_2x":"https:\/\/events.umich.edu\/media\/cache\/event_large_2x\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/event_large_lightbox\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "group_thumb":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "group_thumb_square":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_thumb_square\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "group_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "group_large_lightbox":"https:\/\/events.umich.edu\/media\/cache\/resolve\/group_large_lightbox\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_large_crop":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_large_crop\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_list":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_list\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_list_2x":"https:\/\/events.umich.edu\/media\/cache\/event_list_2x\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_grid":"https:\/\/events.umich.edu\/media\/cache\/event_grid\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_grid_2x":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_grid_2x\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_feature_large":"https:\/\/events.umich.edu\/media\/cache\/resolve\/event_feature_large\/media\/attachments\/2026\/10\/event_153907_original-1.jpg", "event_feature_thumb":"https:\/\/events.umich.edu\/media\/cache\/event_feature_thumb\/media\/attachments\/2026\/10\/event_153907_original-1.jpg" }, "occurrence_count":1, "first_occurrence":21916623 } , "151092-21910859": { "datetime_modified":"20260917T143953", "datetime_start":"20261030T160000", "datetime_end":"20261030T173000", "has_end_time":1, "date_start":"2026-10-30", "date_end":"2026-10-30", "time_start":"16:00:00", "time_end":"17:30:00", "time_zone":"America\/Detroit", "event_title":"CSAS Lecture Series | Beyond the Seas Blue", "occurrence_title":"", "combined_title":"CSAS Lecture Series | Beyond the Seas Blue: Asma Kazmi; Berkeley Center for New Media, University of California-Berkeley", "event_subtitle":"Asma Kazmi; Berkeley Center for New Media, University of California-Berkeley", "event_type":"Lecture \/ Discussion", "event_type_id":"13", "description":"Attend in person or via Zoom: https:\/\/myumi.ch\/E775e\n\nIn this lecture, Kazmi will discuss *Beyond the Seas Blue* alongside earlier projects that connect contemporary technologies to histories of science, material transformation, and knowledge production in the Middle East and South Asia.\n\nAsma Kazmi is an interdisciplinary artist whose work explores the relationships among art, technology, history, and power. Through installations, video, sculpture, virtual environments, and collaborative research, she examines how contemporary technologies emerge from longer histories of science, extraction, trade, and knowledge production. Her work centers connections between the Middle East, South Asia, and the West, often using archives, material culture, and speculative storytelling. Her newest project, *Beyond the Seas Blue*, traces lapis lazuli from the mines of Badakhshan through histories of pigment making, museums, colonial collecting, and digital infrastructure. Kazmi is associate professor of art practice at the University of California, Berkeley, and teaches at the Berkeley Center for New Media.\n\nIf there is anything we can do to make this event accessible to you, please contact us.
