My Career As a Mineral Physicist at Stony Brook: 1976–2019 minerals Editorial My Career as a Mineral Physicist at Stony Brook: 1976–2019 Robert Cooper Liebermann Mineral Physics Institute and Department of Geosciences, Stony Brook University, Stony Brook, NY 11794-2100, USA; [email protected]; Tel.: +001-(631)-766-5711 Received: 14 November 2019; Accepted: 6 December 2019; Published: 7 December 2019 Abstract: In 1976, I took up a faculty position in the Department of Geosciences of Stony Brook University. Over the next half century, in collaboration with graduate students from the U.S., China and Russia and postdoctoral colleagues from Australia, France and Japan, we pursued studies of the elastic properties of minerals (and their structural analogues) at high pressures and temperatures. In the 1980s, together with Donald Weidner, we established the Stony Brook High Pressure Laboratory and the Mineral Physics Institute. In 1991, in collaboration with Alexandra Navrotsky at Princeton University and Charles Prewitt at the Geophysical Laboratory, we founded the NSF Science and Technology Center for High Pressure Research. Keywords: mineral physics; ultrasonic interferometry; high-pressure multi-anvil apparatus; synchrotron X-radiation; CHiPR (Center for High Pressure Research); COMPRES (Consortium for Materials Properties Research in Earth Sciences); Stony Brook University 1. Introduction In March 2013, I was invited by Tetsuo Irifune to give the keynote address at the Final Symposium of G-COE and TANDEM program at Ehime University in Matsuyama, Japan. I chose that opportunity to reflect on my career in mineral physics with the title: “Mineral Physics and Bob-san from 1963 to 2013: Role of Serendipity.” Yanbin Wang was in the audience in Matsuyama and suggested that I submit a manuscript on this topic to Physics of the Earth and Planetary Interiors for a Special Issue for which he was the Guest Editor. When Jay Bass heard of this talk, he recommended that I be asked to reprise this talk after the banquet at the 2013 Annual Meeting of COMPRES at Lake Geneva, Wisconsin in June 2013; I modified the title for the U.S. audience: “Role of Serendipity in My Career in Mineral Physics: 1963 to 2013.” In October 2013, Dan Davis (the Chair of the Department of Geosciences) invited me to give this talk at the weekly Geosciences Colloquium and later to adapt it for the Geosciences Newsletter. This paper is the result and focuses on my career in mineral physics at Stony Brook from 1976 to 2019 and it compliments my earlier paper in Physics of the Earth and Planetary Interiors [1]. 2. Before Stony Brook After being an undergraduate in geophysics at Caltech and obtaining a PhD at Columbia University under Orson Anderson, I spent 6 years at the Australian National University (ANU) in Canberra working in the high-pressure laboratory of Ted Ringwood. When I decided to explore the opportunities to return to the U.S. to a tenure-track faculty position, I was fortunate that the Department of Earth and Space Sciences at Stony Brook was conducting a faculty search led by Don Weidner, who was open-minded enough to consider hiring another mineral physicist. I was encouraged to negotiate an attractive start-up package by Charlie Prewitt and Ted Bence (who were on sabbaticals in Australia at Monash University in Melbourne and the ANU, respectively).

  • Memorial to A. E. (Ted) Ringwood 1930-1993 DAVID H
    Memorial to A. E. (Ted) Ringwood 1930-1993 DAVID H. GREEN Research School of Earth Sciences, Australian National University,Canberra, 0200, Australia With the death of Ted Ringwood on November 12, 1993, earth science lost prematurely one of its most fertile minds and most effective experimental scientists. His professional career was international in its outreach, but centered within the Australian National University. His scientific presenta­ tions at international meetings were characterized by pre­ sentation of new data, by independence and original thought, and by clarity and conviction in presentation. An enthusiast for science, he equally saw that science must solve problems and create opportunities of relevance to society as a whole. Ted Ringwood’s influence in earth sciences has been profound through more than 300 scientific articles and two books, but principally through his vigorous presentation of new concepts and new data and his willingness to confront established models where he perceived them to be narrowly based, internally inconsistent, or inconsistent with observation or experiment. His research, although motivated by fundamental questions about Earth, its origin, nature, and internal processes, also effectively bridged into applied research in the safe disposal of nuclear waste and in the design and manufacture of ultra-hard materials. Projects of both applied science and fundamental science were carried out in the same high-pressure laboratory and with the same creative leadership. He cultivated both a deep theoretical knowledge and experimental skills; both were fired by questioning established models and by a willingness to experiment and to learn from experiment and observation. Ted Ringwood grew up in inner Melbourne, and between 1948 and 1956 he obtained a B.Sc.

  • Some Australian Contributions to Meteoritics from the 19Th to the 21St Centuries
    WA Science—Journal of the Royal Society of Western Australia, 97: 237–252, 2014 Some Australian contributions to meteoritics from the 19th to the 21st Centuries A W R BEVAN Department of Earth and Planetary Sciences, Western Australian Museum, Locked Bag 49, Welshpool DC, WA 6986, Australia. [email protected] Meteorites are fragments of natural debris that survive their fall to Earth from space, and meteoritics is the science of their study. Meteorites are fundamental to our understanding of the origin and early evolution of the Solar System. Many have remained virtually unaltered for 4.56 Ga and represent some of the original materials from which the planets were constructed. From the 19th Century onwards contributions to the understanding of planetary materials have been made by Australian scientists in the fields of meteorite recovery, mineralogy, petrology and metallurgy of meteorites, meteorite classification, isotopic studies, geochronology, impact cratering and Solar System formation. This paper documents some of the significant achievements that have been made. KEYWORDS: chondrites, geochronology, irons, isotopes, meteorites, mineralogy, petrology, stony-irons.

Summons Department of Earth, Atmospheric, and Planetary Sciences, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA, and National Aeronautics and Space Administration (NASA) Astrobiology Institute, MIT Team ABSTRACT Many of the discoveries made in geochemistry over the last 50 yr have been driven by technological advances that have allowed analysis of smaller samples, attainment of better instrumental precision and accuracy or computational capability, and automation that has provided many more data. These advances occurred during development of revolutionary concepts, such as plate tectonics, which has provided an overarching framework for interpreting many geochemical studies. Also, spacecraft exploration of other planetary bodies, including analyses of returned lunar samples and remote sensing of Mars, has added an additional dimension to geochemistry. Determinations of elemental compositions of minerals and rocks, either through in situ analysis by various techniques (e.g., electron microprobe, secondary ion mass spectrometry [SIMS], synchrotron X-ray fl uorescence [XRF], laser ablation) or bulk analysis (e.g., XRF, inductively coupled plasma–atomic emission spectrometry [ICP-AES], inductively coupled plasma–mass spectrometry [ICP-MS]), have become essential approaches to many geochemical studies at levels of sensitivity and spatial resolution undreamed of fi ve decades ago.

    Portraits IN SCIENCE Compiled and introduced by ANN MOYAL SCIENCE IS ONE of the most important intellectual and cultural forces of the twentieth century, yet surprisingly little is known in Australia of the lives of this country's key scientific men and women and of the contributions they have made to enlarging the boundaries of scientific knowledge. Among these interviews compiled and introduced by Ann Moyal there are two physicists, Sir Mark Oliphant and Professor Harry Messel, and three medical researchers in immunology, human genetics and the brain—Sir Gustav Nossal, Professor Susan Serjeantson and Professor Peter Bishop. Others interviewed include an animal geneticist, Dr Helen Newton Turner; ecologist, biologist and Chief Scientist, Professor Ralph Slatyer; Dr Elizabeth Truswell, a palynologist; Dr Paul Wild, a radiophysicist; and Professor Ted Ringwood, physicist. There are also lively interviews with science communicators, Robyn Williams and Dr Michael Gore. Together the group encompasses the innovative application of scientific knowledge since the 1930s; the foundation of scientific research institutions; high-level Australian representation in international science; and policy development and public education in science. They reveal their formative influences, diversely rewarding experiences and outstanding commitment to their demanding and challenging work. This is an impressive record offering evocative reflections and inspiring achievements.

ONE • THE STRUCTURE OF EARTH AND ITS CONSTITUENTS 1-1. EARTH’S INTERIOR: RADIAL STRUCTURE, CHEMICAL COMPOSITION, AND PHASE TRANSFORMATIONS Inferring Earth’s composition is a prerequisite to understanding its evo- lution and dynamics as well as those of planets like it. One might think that the composition of Earth can be easily inferred from the rocks that we can see on Earth’s surface. However, it immediately becomes obvious that these rocks cannot be the major constituent of Earth’s interior be- cause the densities of typical rocks on Earth’s surface, such as granite or basalt, are so small, even if the effects of compression on density are taken into account. Therefore, materials in the deep Earth (and most other plan- ets) are different from those on the surface. What materials are there, and how do we infer the composition of the deep interior of Earth (and other planets)? You may want to drill into Earth, but the deepest drilled hole in the world is in the Kola peninsula in Russia, which is only ∼ 12 km deep (remember that Earth’s radius is 6,370 km). Although some kinds of vol- canoes bring materials from the deep mantle, this sampling is usually lim- ited to ∼ 200 km deep. Therefore, our inference of Earth’s internal struc- ture must be based largely on indirect information. In this connection, both geochemical and geophysical observations are particularly relevant.

Patrick TETE Invité Directeur technique & exploitation, SUEZ Résumé L'objectif général de cette thèse est de transformer les déchets de l’incinération, ultimes et dangereux contenant des métaux lourds, en matériaux minéraux chimiquement stables. L’augmentation de la production des ordures ménagères (OM) est un problème qui concerne et préoccupe le monde entier. Parmi les différentes méthodes de traitement des déchets municipaux, l'incinération est une technologie qui peut fournir une solution efficace et respectueuse pour l'environnement. Le problème de ce traitement est la production de résidus solides ultimes : les REFIOM (cendres) et les MIOM (mâchefers). Les REFIOM peuvent contenir de grandes quantités de composés métalliques toxiques et sont considérés comme des déchets dangereux, ce qui oblige à les placer dans des centres de stockage spécifiques. Trois types de matériaux pour l'immobilisation du plomb et du cadmium ont été étudiés : les vitrocéramiques, les céramiques frittées et les géopolymères. Deux voies de synthèse des vitrocéramiques ont été testées à partir des déchets : i) synthèses avec des « déchets bruts », c’est-à-dire mélange de REFIOM et de MIOM ; ii) synthèses avec des « déchets synthétiques » reconstitués en mélangeant des oxydes commerciaux.

  • Hydration Mechanism in Earth's Mantle Transition Zone Investigated by Neutron Diffraction
    Hydration mechanism in Earth’s mantle transition zone investigated by neutron diffraction 2017, March Narangoo PUREVJAV Graduate School of Natural Science and Technology (Doctor’s Course) Institute for Planetary Materials OKAYAMA UNIVERSITY ABSTRACT Water plays a crucial role for the evolution of Earth and planets. It exists as liquid state on the Earth’s surface but also exists as hydroxyls within solid hydrous minerals in the Earth’s deep interior. The budget of the latter type of water is controversial. The surface liquid water is transported into the deep interior by subducting oceanic slabs. The transported amount of water is much larger than that returning to the surface by magmatism. By previous experimental studies, it has been shown that some of the Earth’s mantle minerals can uptake water within their structures. Mantle transition zone at depths from 410 to 660 km is considered to be the largest reservoir of such water within the bulk Earth, which mainly consists of wadsleyite and ringwoodite mineral phases. It is because these minerals were proved to uptake at most 3 wt.% water in their crystal structures, which is their exclusive property compared with the other upper and lower mantle constituent minerals. Recently, it was demonstrated that a ringwoodite crystal of terrestrial origin was containing around 1.4 wt.% of water. If we assume that the whole lower mantle transition zone is as wet as this ringwoodite, its water is equal with the total mass of the all oceans. By seismological studies, it was revealed that anomalous low- velocity regions existed at the top and the bottom of the mantle transition zone, which can be the results of hydration and dehydration of hydrous wadsleyite and hydrous ringwoodite, respectively.
