Explore the fascinating world of plate tectonic recycling through diamond inclusions in this 24-minute talk by D. Graham Pearson from the University of Alberta. Delve into the power of inclusions, recent diamond formation, and the tools used to study them. Examine P-type inclusions, carbon and nitrogen isotopes, and the proposed solutions for understanding these geological phenomena. Investigate echo joints, carbon recycling, and superdeep diamonds, including their samples and inclusions. Discover the intriguing properties of blue diamonds, their analysis, and range. Gain valuable insights into the recycling of H, C, N, and B through plate tectonics as revealed by diamond records in this comprehensive presentation from the Mineralogical Society of America's Centennial Symposium.
