PRESIDENT'S REPORT … Ralph Bottrill Senior Geologist, Mineralogist and Petrologist, Metallic Minerals & Geochemistry, Mineral Resources Tasmania. Happy New Year to all members! After having our usual Christmas break, there are not too many recent events to report. Our February meeting was entertained by Steve Sorrell, visiting from Ballarat, and lecturing us on methods of Mineral Photography. Peter Manchester gave an interesting short talk on the hardest mineral on Earth. In March Dehne gave a great talk on the Tucson mineral show, making us wish we could all be there! We are progressing with an interesting program for the year, so please keep in touch. “Chrome Cerussite”; Dundas, Tasmania, Australia A variety of Cerussite. Not properly diagnosed yet.

MST 102 8 Data-driven discovery reveals Earth's missing minerals by Timothy Oleson Tim is the news editor at EARTH, and writes the Bare Earth Elements blog. His scientific interests span the geosciences from biogeochemistry to seismology to space science. Fuelled by advances in computing power and analytical methods, researchers in a growing number of scientific fields have taken to mining large datasets to reveal big-picture insights. Like biologists searching for undiscovered species, mineralogists have long sought to fill in the picture of Earth’s mineralogical diversity with new finds. In recent years, mineralogists, teamed with mathematicians and others, have begun using statistical models and data science methods traditionally applied to study large datasets in fields like linguistics, evolutionary biology and social network analysis.

This paper is written to be read by both specialists and a wider audience. However, it contains many mineral names. While these may resonate in the minds of mineralogists or collectors, they may not be as meaningful to less discerning readers. Such readers should not be scared, for they may find excellent encyclopaedic records on the web, including chemical composition, crystallographic properties and description of each of these species. This is why we have decided not to include further information in this paper. Acknowledgements. I would like to thank the mineralogists with whom I have had the opportunity to maintain fruitful exchanges for a long time: my pupil Hubert Bari, Éric Asselborn, Cédric Lheur, François Farges. And I would like to honour the memories of René Weil (1901-1983), my master in descriptive mineralogy, and of Jacques Geffroy (1918-1993), pupil of Alfred Lacroix, my master in metallogeny.

  • The Partnership of Smithson Tennant and William Hyde Wollaston
    “A History of Platinum and its Allied Metals”, by Donald McDonald and Leslie B. Hunt 9 The Partnership of Smithson Tennant and William Hyde Wollaston “A quantity of platina was purchased by me a few years since with the design of rendering it malleable for the different purposes to which it is adapted. That object has now been attained. ” WILLIAM HYDE W O L L A S T O N Up to the end of the eighteenth century the attempts to produce malleable platinum had advanced mainly in the hands of practical men aiming at its pre­ paration and fabrication rather than at the solution of scientific problems. These were now to be attacked with a marked degree of success by two remarkable but very different men who first became friends during their student days at Cam ­ bridge and who formed a working partnership in 1800 designed not only for scientific purposes but also for financial reasons. They were of the same genera­ tion and much the same background as the professional scientists of London whose work was described in Chapter 8, and to whom they were well known, but with the exception of Humphry Davy they were of greater stature and made a greater advance in the development of platinum metallurgy than their predecessors. Their combined achievements over a relatively short span of years included the successful production for the first time of malleable platinum on a truly com­ mercial scale as well as the discovery of no less than four new elements contained in native platinum, a factor that was of material help in the purification and treatment of platinum itself.

    1ll. C. Lea on the Platinum Metala. 81 ART. IX.-Notes on the Platinum, Metals, and their 8l'paration from each other i by M. CAREY LEA, Philadelphia.-Part I. (1) FEW branches of inorganic chemistry present difficulties com­ parable with those involved in the study and separation of the platinum metals. 'rheir close analogy with each other, and the remarkllble manner in which the relations of each to chemical reagents are controlled by the presence of the others, give rise to difficulties in their detection and separation which are only by degrees being surmounted. Much time and unwearied labor on the part of the chemist are required to rench results whith when obtained appear insignificant in proportion to the effort which they cost, and it may ill fnct be said that the platinum metals constitute a chemistry in themselves, governed by special rules and to be studied by special method~. Each step in the simplification of the processes by which the separations are effected, each decisive reaction by which the presence or ab­ sence of a member of the group may be certainly iuferred, is so much gained toward conquering a complete knowledge of these rare and mteresting bodies.

  • High Temperature Sulfate Minerals Forming on the Burning Coal Dumps from Upper Silesia, Poland
    minerals Article High Temperature Sulfate Minerals Forming on the Burning Coal Dumps from Upper Silesia, Poland Jan Parafiniuk * and Rafał Siuda Faculty of Geology, University of Warsaw, Zwirki˙ i Wigury 93, 02-089 Warszawa, Poland; [email protected] * Correspondence: j.parafi[email protected] Abstract: The subject of this work is the assemblage of anhydrous sulfate minerals formed on burning coal-heaps. Three burning heaps located in the Upper Silesian coal basin in Czerwionka-Leszczyny, Radlin and Rydułtowy near Rybnik were selected for the research. The occurrence of godovikovite, millosevichite, steklite and an unnamed MgSO4, sometimes accompanied by subordinate admixtures of mikasaite, sabieite, efremovite, langbeinite and aphthitalite has been recorded from these locations. Occasionally they form monomineral aggregates, but usually occur as mixtures practically impossible to separate. The minerals form microcrystalline masses with a characteristic vesicular structure resembling a solidified foam or pumice. The sulfates crystallize from hot fire gases, similar to high temperature volcanic exhalations. The gases transport volatile components from the center of the fire but their chemical compositions are not yet known. Their cooling in the near-surface part of the heap results in condensation from the vapors as viscous liquid mass, from which the investigated minerals then crystallize. Their crystallization temperatures can be estimated from direct measurements of the temperatures of sulfate accumulation in the burning dumps and studies of their thermal ◦ decomposition. Millosevichite and steklite crystallize in the temperature range of 510–650 C, MgSO4 Citation: Parafiniuk, J.; Siuda, R. forms at 510–600 ◦C and godovikovite in the slightly lower range of 280–450 (546) ◦C.

    Mining Metals, Mining Minds: An Exploration of Georgius Agricola’s Natural Philosophy in De re metallica (1556) By Hillary Taylor Dissertation Submitted to the Faculty of the Graduate School of Vanderbilt University in partial fulfillment of the requirements for the degree of DOCTOR OF PHILOSOPHY in History January 31, 2021 Nashville, Tennessee Approved: William Caferro, Ph.D. Lauren R. Clay, Ph.D. Laura Stark, Ph.D. Elsa Filosa, Ph.D. Francesca Trivellato, Ph.D. For my parents, Jim and Lisa ii Acknowledgements I have benefitted from the generosity of many individuals in my odyssey to complete this dissertation. My sincerest thanks go to Professor William Caferro who showed me how to call up documents at the Archivio di Stato in Florence, taught me Italian paleography, read each chapter, and provided thoughtful feedback. It has been a blessing working closely with a scholar who is as great as he is at doing history. I have certainly learned by his example, watching as he spends his own time reading, translating, writing, and editing. I have attempted to emulate his productivity, and I know that I would not have finished the ultimate academic enterprise without his guidance. Professor Caferro pruned my prose without bruising my ego, too badly. I must also extend my warmest thanks to the other members of my committee, Professor Lauren Clay, Professor Laura Stark, Professor Elsa Filosa, and Professor Francesca Trivellato. I am also grateful to Professor Monique O’Connell, my undergraduate advisor at Wake Forest University. Monique was the first to introduce me to the historiographical complexities of Italian history and intellectual thought.

Ammonium chloride (fume); Health-based Reassessment of Administrative Occupational Exposure Limits. The Hague: Health Council of the Netherlands, 2004; 2000/15OSH/093. all rights reserved 1 Introduction The present document contains the assessment of the health hazard of ammonium chloride fume by the Committee on Updating of Occupational Exposure Limits, a committee of the Health Council of the Netherlands. The first draft of this document was prepared by MA Maclaine Pont, M.Sc. (Wageningen University and Research Centre, Wageningen, the Netherlands). In February 1998, literature was searched in the databases Medline, Toxline, and Chemical Abstracts covering the periods 1966 until February 1998, 1981 until October 1997, and 1937 until December 1997, respectively, and using the following key words: ammonium chloride (and isotopic compounds), NH4Cl, and 12125-02-9. In December 1998, the President of the Health Council released a draft of the document for public review. Comments were received by the following individuals and organisations: A Aalto (Ministry of Social Affairs and Health, Tampere, Finland) and P Wardenbach, Ph.D. (Bundesanstalt für Arbeitsschutz and Arbeitsmedizin, Dortmund, Germany). These comments were taken into account in deciding on the final version of the document. An additional literature search in Toxline and Medline in September 2003 did not result in information changing the committee’s conclusions.
