Recent seismic results showing significant yet heterogeneous seismic anisotropy for the inner core suggest that it is undergoing a dynamic process of unknown origin.<\/p>\n<p style=\"padding:\">This talk presents new methods for measuring transport properties under the high-pressure, high-temperature conditions of the Earth&rsquo;s core, combining synchrotron-based X-ray experiments at high pressure and temperature with post-run focused-ion beam milling and transmission electron microscopy. Combined with models for texture evolution in metals, the mechanism by which the inner core develops and maintains anisotropy appears to be a combination of preferential growth in equatorial regions combined with solid-state deformation in response to mass variations in the Earth&rsquo;s mantle.&#8221;<\/p>\n","protected":false},"author":1,"featured_media":0,"template":"","class_list":["post-3874","physics_colloquium","type-physics_colloquium","status-publish","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium\/3874","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/physics_colloquium"}],"about":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/types\/physics_colloquium"}],"author":[{"embeddable":true,"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/users\/1"}],"wp:attachment":[{"href":"https:\/\/www.hmc.edu\/physics\/wp-json\/wp\/v2\/media?parent=3874"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
