This session is aimed at remembering and honoring Harry W. Green II’s seminal contributions to Earth Science.

Harry was a pioneer in mantle rheology, earthquake physics and UHP metamorphism. Over the course of his career, Harry made significant scientific breakthroughs as described in 20+ Nature and Science papers (including a few covers). Harry was first to use transmission electron microscopy to study of plastic deformation of rocks. He was also a pioneer in using solid-medium deformation apparatus, such as the Griggs-modified piston-cylinder, the multi-anvil and the D-DIA. He quickly understood that mineral transformations could be a potent deformation process under stress and proved experimentally that the transformation of metastable olivine could explain the origin of deep focus earthquakes. In the 1990s, Harry began to study deep-seated rocks from Alpe Arami and NW China. Integrating his extensive knowledge of mineralogy, phase transformations, thermodynamics and experimental high pressure work, he was able to prove, methodically, that the Alpe Arami massif as well as many other metasedimentary rocks containing diamond and coesite after stishovite came from depths greater than 300km. Harry helped to establish the new field of “micro-nano mineralogy” which uses in-depth nano-analysis of microscopic minerals to reveal metamorphic petrogenetic events ranging from earthquakes and meteoritic shock impacts to subduction and exhumation.

We invite contributions from those who have worked with Harry, as well as from those who share his numerous research interests on the interactions between mineralogy, rock deformation, metamorphism at high pressure and Earth’s dynamics.
