  • Dedication
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    This volume is dedicated to my colleague and friend Pete Burnard, who tragically passed away in 2015. Pete’s technical and scientific skills were fundamental in making the noble gas lab at CRPG what it is today, and we continue to miss his endless good sense of humour and kindness.

  • PREFACE
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    When Janne Blichert-Toft came to me with the invitation of writing a volume of Geochemical Perspectives, I already had in mind the desire to write something that was neither strictly a terse scientific article, nor a general undergraduate text. In this sense, GP was a perfect fit, encouraging, as it does, a narrative of scientific advance in a specialised field, blended with personal experience. In

    Bernard Marty

    I am grateful to Janne Blichert-Toft who invited me to write this volume. Without her encouragement and advice, I am not sure it would have come to completion in a reasonable interval of time. Confinement also helped!Science can be a solitary existence but most of the time it is a group effort. I had the good luck of benefitting from guidance and collaborations with great scientists, among them, Minoru

  • ORIGINS AND EARLY EVOLUTION OF THE ATMOSPHERE AND THE OCEANS
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    My journey in science began with the study of volcanic gases, sparking an interest in the origin, and ultimate fate, of the volatile elements in the interior of our planet. How did these elements, so crucial to life and our surface environment, come to be sequestered within the deepest regions of the Earth, and what can they tell us about the processes occurring there? My approach has been to establish

  • 1. A PERSONAL JOURNEY
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    I became interested in volcanoes when I was around six. The trigger was an extraordinary movie on active volcanoes, “Les Rendez-Vous du Diable” (released as “Volcano” in the UK, where it won a British Academy award in 1962) in which lava lakes, lava flows, and Strombolian explosions could be seen as if you were looking into the torrid mouths of volcanoes (Fig. 1.1). Some of the shots were amazing:

  • 2. THE DUAL ORIGIN OF THE ATMOSPHERE AND THE OCEANS
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    The terrestrial atmosphere is a thin layer of gas (Fig. 2.1) which protects the surface of our planet from lethal interactions with outer space and permits the ambient temperature to be maintained between that of boiling water and ice. It is a nicely tuned system that has been autoregulating its composition and temperature for billions of years.The volatile elements discussed here are those defined

  • 3. MAJOR VOLATILES: CARBON AND NITROGEN
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    When I was young, the hotel rooms in the United Kingdom had the reputation of having a strange plumbing system, with noisy and leaking taps and irrational water flows along endless pipelines. This was of course a cliché entertained by the Froggies, but I like to visualise the cycle of terrestrial volatiles a bit like this. The Earth is a carefully tuned system which continuously exchanges its life-supporting

  • 4. INTERMEZZO: VOLCANOES AND FIELD WORK
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    One of the great advantages of being a geoscientist is being able to do field work, or at least justifying adventures in exotic countries by the need to get well-characterised samples. Fieldwork is also a social exercise where you meet and get to know people of diverse cultures and collaborate in sometimes harsh conditions.During my career I joined several field campaigns on active volcanoes in Japan

  • 5. LUNAR VOLATILES: THE LONG-STANDING PROBLEM OF NITROGEN ISOTOPE VARIABILITY AND THE SOURCES OF VOLATLES ON THE MOON
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    In the nineties, geochemists turned more and more to cosmochemistry, the geochemical study of extraterrestrial (ET) material. It seemed to many that mantle geochemistry was going round in circles and was no longer the branch of geochemistry where paradigm changing discoveries could be made. This was quite arrogant and inexact, as new concepts and novel tools including terrestrial extinct radioactivities

  • 6. THE GENESIS MISSION AND THE COMPOSITION OF THE SOLAR NEBULA
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    Every year my CRPG colleagues and I attend the Lunar and Planetary Science Conference (LPSC) in Houston, Texas, which used to be held on the NASA campus south of the city (not so anymore). This was a thrilling place, immortalised in reports on the Gemini and Apollo missions and in Hollywood movies. You would enter the campus through a gate where you were checked by guards, and then you would drive

  • 7. COMETS AS WITNESSES OF THE OUTER SOLAR SYSTEM
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    Comets are small (km-sized) icy bodies that consist of a large proportion of H2O ice accounting for between 10 and 50 % of their mass. They contain organic matter, ice, and silicates/metal in comparable proportions (Greenberg, 1998). Comets have elliptic trajectories that crosscut the midplane of planetary orbits, which mean they can impact planets. In 1994, comet Shoemaker-Levy 9 crashed into Jupiter

  • 8. THE ANCIENT EARTH
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    Life exists on Earth but its existence has not been definitively proven on other planets/worlds. Biological activity might have existed on Mars and, in this respect, the ancient environments of the Red Planet may shed light on the environmental conditions of the ancient Earth. How life developed on our planet is far from fully understood. Whether the origin of life was exogenous (Section 7) or developed

  • 9. CONCLUDING REMARKS
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-10-01
    Bernard Marty

    As a final note, I would like to share a few thoughts about the principles of research. I do not believe that there is just one single path for science. Everyone has their own approach, and mine has not been linear, but composed of opportunities, luck, and failures in equal measure. If you want to discover something completely new, you have to be in a state of uncertainty. It is, however, crucial to

    Take home message. The origin of highly volatile compounds (made of H, C, N, and noble gases) could be interstellar and/or synthesised within the protosolar nebula through ion-molecule exchange and/or interactions between solar/interstellar photons and the gas.•Left: In the inner-most regions of the disk, water ice could not exist.

  • PREFACE

    Lawrence D. Meinert

    I am not sure exactly when I first met Larry Meinert. I certainly knew of him long before I met him; as a stalwart of the Society of Economic Geologists and later, as the Editor of their flagship journal Economic Geology. It is likely that I met him as a post-doc at one of the “Hydrothermal Fluid Society” (HFS) events that Larry organises at various conferences around the globe. To gain access to one

    This issue of Geochemical Perspectives started with an invitation by editorial board member Sarah Gleeson, to go beyond reflection on a scientific career and describe a journey through life (luckily not ended yet, since this issue was written during the early stages of the COVID-19 pandemic). This was a daunting task because my path has not been typical and several parts of the journey epitomise what

  • GEOLOGY, POLICY, AND WINE – THE INTERSECTION OF SCIENCE AND LIFE
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    A full life can encompass many things including education, teaching, editing, research, government service, policy, and wine. Such a life may not even be restricted to Earth but may extend to investigations of asteroids, the Moon, and other planets, such as Mars. Underlying this broad range of interests, mineral resources are the building blocks of civilisation. Geochemistry helps us understand mineral

  • 1. INTRODUCTION
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    Previous Geochemical Perspectives on scientific careers have been deserved celebrations of distinguished scientists, their work, and their science. They range from very large publications (259 pages!) covering the broad field of Mineral-Aqueous Solution Interfaces (Brown and Calas, 2012) to trailblazing applications of isotope geochemistry like Fogel (2019), the first woman to be featured in this series

  • 2. EDUCATION
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    One purpose of the Geochemical Perspectives series on scientific careers is to explore how one became involved with geochemistry in the first place since very few people are aware of this scientific discipline in their early days and unless one’s parents were geochemists it would be easy to sail through one’s primary education without any knowledge or awareness of geochemistry. In my case I was not

  • 3. THE GENESIS AND EXPLORATION OF SKARN DEPOSITS
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    Most of my career has been concerned with mineral resources in one form or another. This general subject was covered in a previous issue of Geochemical Perspectives (Arndt et al., 2017) so I will not repeat that overview treatment here. Instead I focus on my experience with a particular type of ore deposit, skarn deposits, and the unique geochemical laboratory that they represent. In simplest terms

  • 4. TEACHING SCIENCE AND CREATIVE WRITING
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    Most university professors are also teachers. We teach in many different ways and for those in research university positions much of that teaching is in training students, from beginning graduate students to advanced post-doctoral research professionals, how to “do what we do”. Our goal is to educate the next generation of scientists on how to conduct and publish cutting edge research to advance the

  • 5. THOUGHTS ON SCIENTIFIC PUBLISHING
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    It goes without saying that everyone reading this paper has at least some familiarity with the scientific publishing process, if only at the level of reading articles in scientific journals such as Geochemical Perspectives. Most readers also will have published papers on their particular scientific expertise and thus will have experienced the review and revision process along with being the recipient

  • 6. POLICY AND FEDERAL SERVICE
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    My first introduction to policy on a national level came when I moved to Washington DC in 2010, when my wife took a position there. Once relocated, I took the opportunity to apply for and was accepted as a Congressional Fellow. The Congressional Fellowship programme is administered by the American Association for the Advancement of Science (AAAS). The approximately 30 Fellows are selected and funded

  • 7. SPACE RESOURCES
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    Concern about the adequacy of mineral resources on Earth has led some people to propose that space resources might be an alternative solution or perhaps an opportunity to “get rich quick” (e.g.,https://www.rt.com/business/424800-first-trillionaire-spaceminer/). A somewhat humorous illustration of this concept in terms of a “space prospector” is illustrated in Figure 7.1. Others have pointed out the

  • 8. WINE AND TERROIR
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    Geology and geochemistry are not only independent (and interdependent) sciences but they also underlie and support many other fields. These include my personal passion for wine that has been manifested in studies of terroir, and for the past ~37 years, operating a small home winery. Human interest in wine predates written records, as evidenced by archaeological finds in China, Georgia, Greece, Iran

  • 9. FAMILY AND THE FUTURE
    Geochem. Perspect. (IF 3.75) Pub Date : 2020-04-01
    Lawrence D. Meinert

    This issue of Geochemical Perspectives has covered a broad range of topics and the common thread is that they are all things I have experienced during my scientific career. But one thing I have not covered, and it may be the most important of all, is my family. Part of this is because, like most professionals, our family life is a haven from what we do on the job. Also, as scientists we have been trained

  • Siderophile Elements in Tracing Planetary Formation and Evolution.
    Geochem. Perspect. (IF 3.75) Pub Date : 2016-01-01
    Richard J Walker

    The siderophile, or iron-loving elements have many applications in the Earth and planetary sciences. In primitive meteorites, differences in the relative abundances of these elements are likely due to both nebular and parent body processes. In addition, some siderophile elements are also characterised by isotopically distinctive nucleosynthetic signatures. Thus, the relative abundances and isotopic
