MMGM Newsletter March 2017 MMGM Newsletter 99 Main Street • Bethel, Maine • mainemineralmuseum.org • (207) 824-3036 From the Director’s Desk—Meteorite Lecture By Barbra Barrett, MMGM Director Most people are fascinated by a brilliantly starlit sky or bemused when they see a shooting star or better yet a meteor shower. Those fleeting trails of light caused by small particles burning up high in the atmosphere dazzle the child in all of us. Even more phenomenal, larger space debris sometimes falls to earth creating a magnificent glow during its rapid descent. Recovered fragments from these events are meteorites. MMGM will host two special events in April focusing on these extraordinary and educational rocks from space. Last May a very bright fireball was observed over Maine telescopes can observe new Solar Systems forming today most likely resulting in a meteorite fall north of Rangeley and based on the information from the meteorites we Lake. Unfortunately, the meteorite was never found, hope to find new Solar Systems that resemble our own. despite a considerable effort to locate it. Meteorites contain Meteorites bring us closer to understanding the origin of our material from the birth of our Solar System and are used solar system as well as life on our own planet. to understand how and when it formed.

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.

  • New Unique Pyroxene Pallasite: Northwest Africa 10019 C
    78th Annual Meeting of the Meteoritical Society (2015) 5084.pdf NEW UNIQUE PYROXENE PALLASITE: NORTHWEST AFRICA 10019 C. B. Agee, K. Ziegler, N. Muttik. Institute of Meteoritics and the Department of Earth and Planetary Sciences, University of New Mexico. E-mail: [email protected]. Introduction: Pyroxene pallasites were originally defined by the grouplet of Vermillion and Yamato 8451 [1], which have minor amounts (~1-3 vol%) of pyroxene, with oxygen isotope values that are distinct from the pallasite main group (PMG) and the Eagle Station grouplet (PES). In the meantime, additional pyroxene-bearing pallasites, Zinder, NWA 1911, and Choteau, have been discovered [2,3], however each of these meteorites appears to be unique based on oxygen isotopes and mineralogy -- thus not belonging to the original pyroxene pallasite grouplet. Here we report on yet another unique ungrouped pyroxene pallasite, Northwest Africa 10019, which now brings the total of distinct pyroxene pallasite types – possibly all from different parent bodies – to a total of five. History and Physical Chracteristics: NWA 10019 was purchased by Steve Arnold from Morocco in January 2015 and consisted of one 580 gram fusion crusted individual and 26 grams of several small fusion crusted pieces. Saw cuts and thin slices show angular orange-brown-green, translucent olivines (~50 vol%), the largest 28 mm long, with many smaller (0.5-5 mm) angular grains, some of which are darker colored orthopyroxenes (Fs15.4±0.2Wo1.0±0.2, Fe/Mn=23±1, n=6, ~10 vol %), all set in a matrix of taenite (Fe=72.0±4.0, Ni=27.4±2.4, Co=0.19±0.05 wt%, n=5, ~20 vol%) and kamacite (Fe=93.1±2.0, Ni=6.6±0.2, Co=0.61±0.03 wt%, n=4, ~15 vol %).
