Disequilibrium Melting and Melt Migration Driven by Impacts: Implications for Rapid Planetesimal Core Formation
Available online at www.sciencedirect.com Geochimica et Cosmochimica Acta 100 (2013) 41–59 www.elsevier.com/locate/gca Disequilibrium melting and melt migration driven by impacts: Implications for rapid planetesimal core formation Andrew G. Tomkins ⇑, Roberto F. Weinberg, Bruce F. Schaefer 1, Andrew Langendam School of Geosciences, P.O. Box 28E, Monash University, Melbourne, Victoria 3800, Australia Received 20 January 2012; accepted in revised form 24 September 2012; available online 12 October 2012 Abstract The e182W ages of magmatic iron meteorites are largely within error of the oldest solar system particles, apparently requir- ing a mechanism for segregation of metals to the cores of planetesimals within 1.5 million years of initial condensation. Cur- rently favoured models involve equilibrium melting and gravitational segregation in a static, quiescent environment, which requires very high early heat production in small bodies via decay of short-lived radionuclides. However, the rapid accretion needed to do this implies a violent early accretionary history, raising the question of whether attainment of equilibrium is a valid assumption. Since our use of the Hf–W isotopic system is predicated on achievement of chemical equilibrium during core formation, our understanding of the timing of this key early solar system process is dependent on our knowledge of the seg- regation mechanism. Here, we investigate impact-related textures and microstructures in chondritic meteorites, and show that impact-generated deformation promoted separation of liquid FeNi into enlarged sulfide-depleted accumulations, and that this happened under conditions of thermochemical disequilibrium. These observations imply that similar enlarged metal accumu- lations developed as the earliest planetesimals grew by rapid collisional accretion. -

Abstract The calcium stable isotopic compositions of mantle-sourced rocks and minerals were investigated to better understand the carbon cycle in the Earth’s mantle. Bulk carbonatites and kimberlites were analyzed to identify a geochemical signature of carbonatite magmatism, while inter-mineral fractionation was measured in co-existing Ca-bearing carbonate and silicate minerals. Bulk samples show a range of composition deviating from the bulk silicate Earth δ44/40Ca composition indicating signatures of magmatic processes or marine carbonate addition 44/40 to source materials. Δ Cacarbonate-silicate values range from -0.55‰ to +1.82‰ and positively correlate with Ca/Mg ratios in pyroxenes. -

James Hutton's Reputation Among Geologists in the Late Eighteenth and Nineteenth Centuries
The Geological Society of America Memoir 216 Revising the Revisions: James Hutton’s Reputation among Geologists in the Late Eighteenth and Nineteenth Centuries A. M. Celâl Şengör* İTÜ Avrasya Yerbilimleri Enstitüsü ve Maden Fakültesi, Jeoloji Bölümü, Ayazağa 34469 İstanbul, Turkey ABSTRACT A recent fad in the historiography of geology is to consider the Scottish polymath James Hutton’s Theory of the Earth the last of the “theories of the earth” genre of publications that had begun developing in the seventeenth century and to regard it as something behind the times already in the late eighteenth century and which was subsequently remembered only because some later geologists, particularly Hutton’s countryman Sir Archibald Geikie, found it convenient to represent it as a precursor of the prevailing opinions of the day. By contrast, the available documentation, pub- lished and unpublished, shows that Hutton’s theory was considered as something completely new by his contemporaries, very different from anything that preceded it, whether they agreed with him or not, and that it was widely discussed both in his own country and abroad—from St. Petersburg through Europe to New York. By the end of the third decade in the nineteenth century, many very respectable geologists began seeing in him “the father of modern geology” even before Sir Archibald was born (in 1835). Before long, even popular books on geology and general encyclopedias began spreading the same conviction. A review of the geological literature of the late eighteenth and the nineteenth centuries shows that Hutton was not only remembered, but his ideas were in fact considered part of the current science and discussed accord- ingly.
