  • Disequilibrium Melting and Melt Migration Driven by Impacts: Implications for Rapid Planetesimal Core Formation

    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.

A total of 737 clubs entered the FFA Cup 2019, a number that has significantly grown from the first edition of the FFA Cup in 2014, when 617 clubs entered. The FFA Cup 2019 started in February with the Preliminary Rounds to determine the 21 clubs from the semi-professional and amateur tiers. These clubs joined ten of the Hyundai A-League clubs (Western United FC will not participate in this edition) and the reigning National Premier Leagues Champions (Campbelltown City SC) in the Final Rounds. The FFA Cup Final 2019 will be played on Wednesday 23 October with the host city to be determined by a live draw. Each cup tie must be decided on the day, with extra time to decide results of matches drawn after 90 minutes, followed by penalties if required. At least one Member Federation club is guaranteed to progress to the Semi Finals. Previous winners of the FFA Cup are Adelaide United (2014 and 2018), Melbourne Victory (2015), Melbourne City FC (2016) and Sydney FC (2017). Broadcast partners – FOX SPORTS FOX SPORTS will again provide comprehensive coverage of the FFA Cup 2019 Final Rounds. The FFA Cup’s official broadcaster will show one LIVE match per match night from the Round of 32 onwards, while providing coverage and updates, as well as live streams, of non-broadcast matches.

Martinez2, Akira Tsuchiyama3, and Akira 4 Miyake3 5 1ARES, NASA Johnson Space Center, Houston, Texas 77058, USA. 6 2Jacobs Engineering, Houston, Texas 77058, USA. 7 3Graduate School of Science, Kyoto University, Kitashirakawa Oiwake-cho, Sakyo-ku, Kyoto 8 606-8502, Japan. 9 10 Correspondence to: Queenie H. S. Chan. Correspondence and requests for materials should be 11 addressed to Q.H.S.C. (Email: [email protected]) 12 13 Abstract 14 Life on Earth shows preference towards the set of organics with particular spatial configurations. 15 Enantiomeric excesses have been observed for α-methyl amino acids in meteorites, which 16 suggests that chiral asymmetry might have an abiotic origin. A possible abiotic mechanism that 17 could produce chiral asymmetry in meteoritic amino acids is their formation under the influence 18 of asymmetric catalysts, as mineral crystallization can produce spatially asymmetric structures. 19 Although magnetite plaquettes have been proposed to be a possible candidate for an asymmetric 20 catalyst, based on the suggestion that they have a spiral structure, a comprehensive description of 21 their morphology and interpretation of the mechanism associated with symmetry-breaking in 22 biomolecules remain elusive. Here we report observations of magnetite plaquettes in 1 23 carbonaceous chondrites (CCs) which were made with scanning electron microscopy and 24 synchrotron X-ray computed microtomography (SXRCT). We obtained the crystal orientation of 25 the plaquettes using electron backscatter diffraction (EBSD) analysis. SXRCT permits 26 visualization of the internal features of the plaquettes.

ABSTRACT, A primary goal of-the Apollo missions was the exploration and scientific study of the moon. The nature of the lunar interior is of particular interest for comparison with the earth and in studying comparative planetology. The principal experiment designed to study the lunar interior was the passive seismic experiment (PSE) included as part of the science package on missions 12, 14, 15, and 16. Thus seis­ mologists were provided with a uniqueopportunity ta study the seismicity and seismic characteristics of a second planetary 'bdy and ascertain if analysis methods developed on earth could illuminate the structure of the lunar interior. The lunar seismic data differ from terrestrial data in three major respects. First, the seismic sources are much smaller than on earth, so that no significant information has -been yet obtained for the 4v/ry deep lunar interior. Second, a strong, high Q scattering layer exists on the surface of the moon, resulting in very emergent seismic arrivals, long ringing-codas that obscure secondary (later arriving)-phases., and 'the-destruction of coherent dispersed surface wave trains.

However, our detailed in- Terra along with parts of sorrounding units based on vestigation of the volcano using CTX data reveals new -1 Context Camera [1] (CTX) image data at ˜6 mpx insights into relative and absolute stratigraphic relations resolution. CTX data gaps that only make out a few between volcanic emplacement and rifting. Narrow lava percent of the mapping area were filled with data flows (Fig.1a) which represent later eruptions and acquired by the High Resolution Stereo Camera [2, 3] should therefore be younger than 3.53 Ga (or 3.51 Ga) (HRSC) at resolutions between 12.5 to 25 mpx-1. While are cut by major curvlinear border faults of Tempe Fos- the focus of this map lies on the study of recent surface sae and linear, narrow faults of Mareotis Fossae. Thus, processes and the complex volcano-tectonic history rifting or at least faulting seems to have been active after that has sustainably shaped Tempe Terra, adjacent the latest eruptions. units associated with the formation of major geologic Ancient lakes and river beds: In the eastern part regions (Arcadia Planitia, Kasei Valles, Tharsis) were of Tempe Terra, Nochian cratered units are often carved also included to get a comprehensive insight in the by irregular, often labyrinth-like, flat-floored and rim- regional geology.
