USGS Open-File Report 2005-1190, Table 1
TABLE 1 GEOLOGIC FIELD-TRAINING OF NASA ASTRONAUTS BETWEEN JANUARY 1963 AND NOVEMBER 1972 The following is a year-by-year listing of the astronaut geologic field training trips planned and led by personnel from the U.S. Geological Survey’s Branches of Astrogeology and Surface Planetary Exploration, in collaboration with the Geology Group at the Manned Spacecraft Center, Houston, Texas at the request of NASA between January 1963 and November 1972. Regional geologic experts from the U.S. Geological Survey and other governmental organizations and universities s also played vital roles in these exercises. [The early training (between 1963 and 1967) involved a rather large contingent of astronauts from NASA groups 1, 2, and 3. For another listing of the astronaut geologic training trips and exercises, including all attending and the general purposed of the exercise, the reader is referred to the following website containing a contribution by William Phinney (Phinney, book submitted to NASA/JSC; also http://www.hq.nasa.gov/office/pao/History/alsj/ap-geotrips.pdf).] 1963 16-18 January 1963: Meteor Crater and San Francisco Volcanic Field near Flagstaff, Arizona (9 astronauts). Among the nine astronaut trainees in Flagstaff for that initial astronaut geologic training exercise was Neil Armstrong--who would become the first man to step foot on the Moon during the historic Apollo 11 mission in July 1969! The other astronauts present included Frank Borman (Apollo 8), Charles "Pete" Conrad (Apollo 12), James Lovell (Apollo 8 and the near-tragic Apollo 13), James McDivitt, Elliot See (killed later in a plane crash), Thomas Stafford (Apollo 10), Edward White (later killed in the tragic Apollo 1 fire at Cape Canaveral), and John Young (Apollo 16). -
CNC/IUGG: 2019 Quadrennial Report
CNC/IUGG: 2019 Quadrennial Report Geodesy and Geophysics in Canada 2015-2019 Quadrennial Report of the Canadian National Committee for the International Union of Geodesy and Geophysics Prepared on the Occasion of the 27th General Assembly of the IUGG Montreal, Canada July 2019 INTRODUCTION This report summarizes the research carried out in Canada in the fields of geodesy and geophysics during the quadrennial 2015-2019. It was prepared under the direction of the Canadian National Committee for the International Union of Geodesy and Geophysics (CNC/IUGG). The CNC/IUGG is administered by the Canadian Geophysical Union, in consultation with the Canadian Meteorological and Oceanographic Society and other Canadian scientific organizations, including the Canadian Association of Physicists, the Geological Association of Canada, and the Canadian Institute of Geomatics. The IUGG adhering organization for Canada is the National Research Council of Canada. Among other duties, the CNC/IUGG is responsible for: • collecting and reconciling the many views of the constituent Canadian scientific community on relevant issues • identifying, representing, and promoting the capabilities and distinctive competence of the community on the international stage • enhancing the depth and breadth of the participation of the community in the activities and events of the IUGG and related organizations • establishing the mechanisms for communicating to the community the views of the IUGG and information about the activities of the IUGG. The aim of this report is to communicate to both the Canadian and international scientific communities the research areas and research progress that has been achieved in geodesy and geophysics over the last four years. The main body of this report is divided into eight sections: one for each of the eight major scientific disciplines as represented by the eight sister societies of the IUGG. -

Most analyses were taken after rock vide x-ray excitation with alpha-particles (PIXE) and surfaces were abraded in order to eliminate surface x-ray radiation (XRF). This combination allows x-ray contamination.

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

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. -

Australian Aborigines and Meteorites
Records of the Western Australian Museum 18: 93-101 (1996). Australian Aborigines and meteorites A.W.R. Bevan! and P. Bindon2 1Department of Earth and Planetary Sciences, 2 Department of Anthropology, Western Australian Museum, Francis Street, Perth, Western Australia 6000 Abstract - Numerous mythological references to meteoritic events by Aboriginal people in Australia contrast with the scant physical evidence of their interaction with meteoritic materials. Possible reasons for this are the unsuitability of some meteorites for tool making and the apparent inability of early Aborigines to work metallic materials. However, there is a strong possibility that Aborigines witnessed one or more of the several recent « 5000 yrs BP) meteorite impact events in Australia. Evidence for Aboriginal use of meteorites and the recognition of meteoritic events is critically evaluated.

However, Within the continent there are two significant areas despite abundant evidence throughout the world for the recovery of meteorites: the Nullarbor that many other ancient civilizations recognised, Region, and the area around the Menindee Lakes utilized and even revered meteorites (particularly of western New South Wales.
