Overview

Modern Advances in the Understanding of Diamond Formation


Details

While conventional research on diamond formation has focused on the lithosphere, scientists are starting to recognize the abundance of diamonds from the deeper parts of the earth. This presentation will examine the latest exploration models for diamond and the potential for discovering new diamond sources in “unconventional” settings.


Speakers

DR. ULRIKA F.S. D’HAENENS-JOHANSSON

Senior Research Scientist

GIA New York

THE LESEDI LA RONA AND THE CONSTELLATION – THE PUZZLE OF THE LARGE ROUGH DIAMONDS FROM KAROWE

Biography

Dr. Ulrika F.S. D’Haenens-Johansson is senior research scientist for GIA Research and Development in New York. Her research areas include defect physics of natural, treated, and synthetic diamond materials using optical and EPR spectroscopy. She holds a PhD in physics from the University of Warwick, United Kingdom.


DR. D. GRAHAM PEARSON

Professor of Geology

University of Alberta, Department of Earth and Atmospheric Sciences

MODERN ADVANCES IN THE UNDERSTANDING OF DIAMOND FORMATION

Biography

Dr. D. Graham Pearson is one of the world’s leading scientists in diamond studies and the formation of diamond-forming roots beneath continents. He is at the forefront of developing new techniques for geochemical analysis, and has pioneered methods of dating minute geological samples. He developed the first method for dating single inclusions in diamonds and a novel ultra-low trace element measurement method for measuring the impurity content of diamonds to parts per trillion. Dr. Pearson is a Fellow of the Royal Society of Canada.


DR. STEVEN SHIREY

Senior Research Scientist

Carnegie Institution for Science

HOW TO OBTAIN AND INTERPRET DIAMOND AGES

Biography

Dr. Steven Shirey is a senior research scientist, geochemistry, in the Department of Terrestrial Magnetism of the Carnegie Institution in Washington, DC. His research focuses on how Earth’s continents formed. These studies led to his recent work on diamonds and their mineral inclusions that represent the deepest, oldest, and most pristine mantle samples known. Dr. Shirey received a PhD in geochemistry from the State University of New York at Stony Brook before joining the Carnegie staff in 1985.


DR. THOMAS STACHEL

Professor

University Of Alberta

DIAMOND PRECIPITATION FROM HIGH-DENSITY CHO FLUIDS

Biography

Dr. Thomas Stachel has more than 20 years of research experience on diamonds and their inclusions. Since 2001, he has been professor and Canada Research Chair in Diamonds at the University of Alberta, where he heads the De Beers Laboratory for Diamond Research and the Canadian Centre for Isotopic Microanalysis. His principal research interest is diamond formation in the earth’s mantle. Prof. Stachel holds a PhD from the University of Würzburg in Germany.
