GSA TODAY • Employment Service, P
Vol. 7, No. 7 July 1997 INSIDE • Call for Editors, p. 15 GSA TODAY • Employment Service, p. 21 • 1997 GSA Annual Meeting, p. 28 A Publication of the Geological Society of America Evidence for Life in a Martian Meteorite? Harry Y. McSween, Jr. Department of Geological Sciences, University of Tennessee, Knoxville, TN 37996 ABSTRACT The controversial hypothesis that the ALH84001 mete- orite contains relics of ancient martian life has spurred new findings, but the question has not yet been resolved. Organic matter probably results, at least in part, from terrestrial contamination by Antarctic ice meltwater. The origin of nanophase magnetites and sulfides, suggested, on the basis of their sizes and morphologies, to be biogenic remains con- tested, as does the formation temperature of the carbonates that contain all of the cited evidence for life. The reported nanofossils may be magnetite whiskers and platelets, proba- bly grown from a vapor. New observations, such as the possi- ble presence of biofilms and shock metamorphic effects in the carbonates, have not yet been evaluated. Regardless of the ultimate conclusion, this controversy continues to help define strategies and sharpen tools that will be required for a Mars exploration program focused on the search for life. INTRODUCTION Since the intriguing proposal last summer that martian mete- orite Allan Hills (ALH) 84001 contains biochemical markers, bio- genic minerals, and microfossils (McKay et al., 1996), scientists and the public alike have been treated to a variety of claims sup- porting or refuting this hypothesis. Occasionally, the high visibil- ity of the controversy has overshadowed the research effort (e.g., Begley and Rogers, 1997), but I believe that science will benefit significantly from this experience. -

Portrait of Mary Anning, in oils, probably painted by William Gray in February, 1842, for exhibition at the Royal Academy, but rejected. The portrait includes the fossil cliffs of Lyme Bay in the background. Mary is pointing at an ammonite, with her companion Tray dutifully curled beside the ammonite protecting the find. The portrait eventually became the property of Joseph, Mary‟s brother, and in 1935, was presented to the Geology Department, British Museum, by Mary‟s great-great niece Annette Anning (1876-1938). The portrait is now in the Earth Sciences Library, British Museum of Natural History. A similar portrait in pastels by B.J.M. Donne, hangs in the entry hall of the Geological Society of London. -
Vm Goldschmidt
NORSK GEOLOGISK TIDSSKRIFT 27. 143 V. M. GOLD SCHMIDT Minnetale i Norsk geologisk forening 10. april 1947 Av IVAR OFTEDAL Med professor V. M. Goldschmidts død den 20. mars 1947 var det en av våre store, en vitenskapsmann av verdensformat, som gikk bort. Han døde av hjerneblødning i sitt hjem i Vestre Aker umid delbart etter at han var kommet hjem fra sykehus etter en mindre operasjon. I de siste årene var hans helbred meget dårlig, og en sterkt medvirkende årsak til dette var utvilsomt den voldsomme nerve påkjenning han var utsatt for i de første okkupasjonsårene her i Oslo. Da jødeforfølgelsen her antok åpenlyse former var hans stilling lite misunnelsesverdig. Han ble innkalt til forhør på Victoria Terrasse, senere arrestert og sendt til Berg med en av de beryktete jødetran sporter ennå før Berg-leiren hadde det nødtørftigste utstyr til å ta imot fanger. Her ble han alvorlig syk og kom heldigvis snart på Tønsberg sykehus, hvorfra han fikk reise hjem. Men trygg følte han seg ikke, og det hadde han heller ikke grunn til. Snart ble han, tross alle forsikringer, arrestert igjen, og denne gangen kom han helt til landgangen på vei ombord i et av jødetransportskipene til Tysk land, da han plutselig fikk beskjed om at han var fri. Etter disse opplevelser var Goldschmidts nervesystem, som rimelig kan være, temmelig nedbrutt, og det endte med at han straks før jul 1942 ble med en transport til Sverige. Etter et opphold her kom han over til Storbritannia, hvor han først var en tid i Skottland, siden ved Rothamsted Experimental Station i Harpenden nær London. -

Newsletter 2017-18 Department of GEOSCIENCES From the Department Head Hi alums: I hope this newsletter finds you in good health and spirits. It’s been a very exciting and productive year in the department. In case the news hasn’t reached you, Lee Kump was recently named the seventeenth dean of the College of Earth and Mineral Sciences. We are incredibly proud of Lee for this major honor and we know that the college will benefit greatly under his dedicated and sage leadership. Lee’s vision and energy has left the department a much better place. I’m sure all of the faculty will join me in thanking him for a job very well done. I’ve just re-stepped into the headship for a year as we conduct a national search for a new leader. Lee plans to keep an active research program, but it’s still a bittersweet time for many of us with the retirements of Mike Arthur and Terry Engelder, although we expect both of them to be in the department regularly. You can read more about Mike’s and Terry’s incredible careers in this issue, but needless to say we are going to miss these inspirational scientists. Mike “Black Shale” Arthur wrote the textbook on how ancient organic-rich rocks accumulated, and christened the field of chemostratigraphy. Terry “Marcellus” Engelder had one of the most productive late careers on record with his discovery of fracturing patterns in the Marcellus Shale that helped pave the way for gas production in our state. It’s been fun to watch the career paths of these two very different scientists converge in recent years. -
WM White Geochemistry Chapter 7: Trace Elements
W. M. White Geochemistry Chapter 7: Trace Elements Chapter 7: Trace Elements in Igneous Processes 7.1 INTRODUCTION n this chapter we will consider the behavior of trace elements, particularly in magmas, and in- troduce methods to model this behavior. Though trace elements, by definition, constitute only a I small fraction of a system of interest, they provide geochemical and geological information out of proportion to their abundance. There are several reasons for this. First, variations in the concentrations of many trace elements are much larger than variations in the concentrations of major components, of- ten by many orders of magnitude. Second, in any system there are far more trace elements than major elements. In most geochemical systems, there are 10 or fewer major components that together account for 99% or more of the system. This leaves 80 trace elements. Each element has chemical properties that are to some degree unique, hence there is unique geochemical information contained in the varia- tion of concentration for each element. Thus the 80 trace elements always contain information not available from the variations in the concentrations of major elements. Third, the range in behavior of trace elements is large and collectively they are sensitive to processes to which major elements are in- sensitive. One example is the depth at which partial melting occurs in the mantle. When the mantle melts, it produces melts whose composition is only weakly dependent on pressure, i.e., it always pro- duces basalt. Certain trace elements, however, are highly sensitive to the depth of melting (because the phase assemblages are functions of pressure). -

THE MINERALOGICAL MAGAZINE AND JOURNAL OF THE MINERALOGICAL SOCIETY No. 131. December, 1930. Vol. XXII. Biographical notices of mineralogists recently deceased. (Fourth series.) 1 By L. J. SPENCER, M.A., Sc.D., F.R.S. Keeper of Minerals in the British Museum of Natural History. [Communicated June 3, 1930.] N the following list of 40 lives, with a range in ages from 32 to I 91 years, the average age is 68.2 years. Including previous lists, the average of 384 lives is 64.9 years. ARAUJO FERI~AZ (Jorge Belmiro de) [1883-1926], Brazilian mineralogist, was born at Rio de Janeiro on August 30, 1883, the son of Baron de Arau]o Ferraz, and died there on February 7, 1926. He studied at the polytechnic school of his native city, taking the degree of doctor in civil engineering. After teaching physics and chemistry in the municipal school at Rio de Janeiro and in the School of Mines at Ouro Preto, he was appointed petrographer on the Geological and Mineralogical Survey of Brazil, of which for a time he acted as director. Dr. Araujo Ferraz had an extensive private collection, and he was responsible for the display of Brazilian minerals at the Torino exhibition in 1911 and at the Brazilian centenary exhibition in 1922. He translated and edited E. Hussak's work, ' 0s satellites do diamante' [Min. Mag. 18-148], and for many years had worked on a mineralogy of Brazil, portions of which have been edited by A. Roeeati [Min. Abstr. 3-446]. The mineral ferrazite, named after him; is one of the ' favas' from the Brazilian 1 Series I-III in Min. -
