Curator Comments
Kevin Righter, NASA-JSC
This newsletter reports 215 new meteorites from the 2010, 2012, 2013 and 2014 ANSMET seasons from Patuxent Range (PAT10), Gardner Range (GDR12), Graves Nunataks (GRA12), Grosvenor Mountains (GRO12), Larkman Nunatak (LAR12), Scott Icefield (SCO12), Szabo Bluff (SZA12), Miller Range (MIL13), and Dominion Range (DOM14) areas. Meteorites include several L3.X chondrites, three EH3 chondrites, CK5, CM1, CM2, and CO3 (4) chondrites, a highly shocked ureilite, and a howardite.
We frequently get questions about how many samples have been collected and how many announced, etc., from the US collection. So, here is an update on the numbers, with the recent field team collecting 569 specimens, the total collected by ANSMET teams is ~21,788. Why the “~” you ask? In most field seasons there are terrestrial samples amidst the collection and we slowly discover these as we classify all the samples, so we therefore cannot give a specific number until all samples are classified. As of the Fall 2015 newsletter, we have classified and announced 19926 samples (+ those announced in this newsletter bring the total to 20,143). Finally, just for more numbers — we have received 3308 sample requests since 1978.
Reminder to sign and return your annual inventory
US Antarctic meteorite inventories were mailed to all PIs in the Fall of 2015. You received a list of samples with a header at the top for two signatures — one for you (the PI) and one for an institutional official. If you haven’t already, please follow these instructions:
- Print the list
- Compare your sample list to samples in your possession
- Confirm samples are in your possession unless consumed during research (if approval was obtained during original sample request)
- Sign/date top of first inventory page
- Institutional official must sign/date top of first page
- Scan and email it back to us
PIs that do not respond to inventory queries by the NASA Curator will not continue to receive samples from the collection.
Reminder to acknowledge samples received from NASA-JSC
When publishing results of your research, please include the split numbers used in the research.
We also request that scientists use the following acknowledgement statement when reporting the results of their research in peer reviewed journals: “US Antarctic meteorite samples are recovered by the Antarctic Search for Meteorites (ANSMET) program which has been funded by NSF and NASA, and characterized and curated by the Department of Mineral Sciences of the Smithsonian Institution and Astromaterials Curation Office at NASA Johnson Space Center.” Such an acknowledgement will broaden the awareness of the funding mechanisms that make this program and these samples possible.
We suggest you find out how to acknowledge samples received from all the collections/museums from which you have received materials so that all the institutions making samples available to you receive proper credit and acknowledgement.
Reclassification
LAR 06877 : LAR 06877 was announced as a IIIAB iron in Antarctic Meteorite Newsletter vol. 30, no. 2 (August 2007). Subsequent analysis by John Wasson indicates the need for a reclassification. The INAA analyses of 4.07 mg/g Co, 88.3 mg/g Ni, 2.24 mg/g Ga, 10.5 mg/g As, 0.40 mg/g W, 0.83 mg/g Ir and 1.98 mg/g Au demonstrate that LAR 06877 is in fact a IVA iron.
LAR 06507 : LAR 06507 was classified as an LL impact melt breccia in the Antarctic Meteorite Newsletter vol. 33 No. 1 (February 2010). More detailed information has led to a better understanding of this sample, which we here re-classify to shocked CK6 chondrite, based on a) the abundance of magnetite, the near absence of metal, equilibrated olivine fayalite content of 31±3, and Ni-rich olivine. Additional information can be found in meeting abstracts:

Finally, the following chondrites were mis-classified in last newsletter due to a mix-up in sample numbering. The correct classifications are as follows, with the classification based on fayalite content of olivine determined by electron microscopy:

Magnetic susceptibility measurements
We have been measuring magnetic susceptibility values for many of the new meteorites that come through the meteorite processing lab here at JSC. However, none of it has yet been made available. Here we provide these numbers of a large number of samples from various field seasons. The measurements were made using an SM30 magnetic susceptibility meter, following the guidelines discussed by Folco et al. (2006) and Gattacceca et al. (2004). Two measurements are made on different convex surfaces and then averaged. The measurements were made in the center of the lab, several meters away from any metal tables or cabinets. Although we do not use any of the data yet to reclassify samples, we think it is potentially valuable to the community and so decided to publish it here in the newsletter.

ANSMET 2015 – 2016 Field Season
Ralph Harvey, Jim Karner and John Schutt, Case Western Reserve University
Our 2015–16 field season was a return to the Miller Range icefields, home of the MIL meteorites. These icefields have been visited eight times by ANSMET and are one of our most prolific meteorite recovery sites, yielding over 2500 specimens including just about every kind of meteorite imaginable — lunar, martian, iron, stony-iron, chondrite, etc. This season we aimed to visit icefields in both the northern and southern areas of the Miller Range, spending about two weeks at the north end and four weeks at the south.
Windrows at an icefield in the north Miller Range with flags marking meteorites
The season started with Jim Karner, Brian Rougeux, Nina Lanza, and Morgan Martinez being put-in at the central Iggy Ridge landing site on December 15. The four of us quickly set up camp just as strong katabatic winds from the south started to pick up. The winds continued to blow, and for the next two days it was full-on, whiteout-blizzard conditions as the winds raged at 30–35 mph with gusts up to 50 mph. We ended up stuck in our tents for the first three days of the season. On December 18 the winds started to settle and we finally were able to get out of the tents and dig out camp. The rest of the team—John Schutt, Con Tsang, Cindy Evans, and Ellen Crapster-Pregont—arrived at N. MIL later that day and organized searching started up the next morning. The team performed several days worth of recon style searching on skidoos over blue ice areas near and far from camp, finding about two dozen meteorites. We also spent time foot-searching for meteorites in wind-blown rows of rocks on an icefield north of camp along the eastern margin of the Nimrod Glacier. These windrows contain loads of terrestrial rocks but also a significant number of meteorites—we found and collected about 150 meteorites in two days of searching.
After two weeks we moved about 35 km to the south and setup camp at the southern icefields of the Miller Range. Sunny and warm weather allowed us to search for 11 of the next 12 days, and over two hundred more meteorites were collected. Then the winds came again. This time it was a four-day blow and again we waited it out, confined to our tents. After the storm we resumed searching for a few days until pullout operations started on January 19. Overall it was a good, productive season—we covered a lot of previously unsearched areas and finished several icefields left over from previous seasons. In total we recovered 569 meteorites, of which several have the potential to be pretty special. But isn't that always the case with the Miller Range? After having visited the site every other year for over 10 years, there's at least one more season to go.
Report from the Smithsonian

This newsletter announces the classification of 215 meteorites from the 2010 through 2014 ANSMET seasons.
The Division of Meteorites at the Smithsonian is happy to report that things have been looking up since our last newsletter! Julie Hoskin joined us on August 10th and has come up to speed quickly as our Collections Manager. We also have a new intern, Chris Anders, who has been invaluable in keeping things moving along in our Division. Chris is wiling to do anything and everything asked of him without complaint, and has a keen eye for problem solving. Chris has been instrumental in helping us implement the switch from oil immersion to SEM-EDS analyses for classifying the ordinary chondrite chips, and has had some great ideas about how to make the process (which is still in flux) run smoothly. We have been able to make significant progress toward clearing the backlog of loan requests with Julie and Chris on board. Thanks goes out to both of them!

Classification of the ordinary chondrites in Table 1 & 2 was done by Energy Dispersive Spectroscopic (EDS) methods using a Scanning Electron Microscope (SEM). This can include the analysis of several olivine and pyroxene grains to determine the approximate Fayalite and Ferrosilite values of the silicates, grouping them into H, L or LL chondrites. Petrologic types are determined by optical microscopy and are assigned based on the distinctiveness of chondrule boundaries on broken surfaces of a 1-3 g chip. While this technique is suitable for general characterization and delineation of equilibrated ordinary chondrites, those undertaking detailed study of any meteorite classified by optical methods alone should use caution. It is recommended that a polished thin section be requested to accompany any chip and appropriate steps for a more detailed characterization should be undertaken by the user.
We look forward to introducing Julie to the Meteoritics community at LPSC in March, and are confident that you will enjoy working with her. Her contact info is hoskinj@si.edu and 202-633-1825.
For those of you waiting for iron meteorite requests, we were able to fill many of the smaller requests, but our iron cutting saw met with a rather large hiccup. The repairs and modifications have been made and we should be getting to the requests we were unable to fill in the next couple of weeks. Our continued apologies and please bear with us as our Museum undergoes major renovations, which required us to move the entire rock-cutting lab.
