Magnetism and mineralogy of Almahata Sitta polymict ureilite (= asteroid 2008 TC3): Implications for the ureilite parent body magnetic field
The Almahata Sitta meteorite is the first case of recovered extraterrestrial material originating from an asteroid that was detected in near Earth space shortly before entering and exploding in the high atmosphere. The aims of our project within the 2008 TC3 consortium were investigating Almahata Sitta’s (AS) magnetic signature, phase composition and mineralogy, focussing on the opaque minerals...
متن کاملAlmahata Sitta (=asteroid 2008 TC3) and the search for the ureilite parent body
This article explores what the recovery of 2008 TC3 in the form of the Almahata Sitta meteorites may tell us about the source region of ureilites in the main asteroid belt. An investigation is made into what is known about asteroids with roughly the same spectroscopic signature as 2008 TC3. A population of low-inclination near-Earth asteroids is identified with spectra similar to 2008 TC3. Five...
متن کاملDepartment of Mineralogy , Petrography and Geochemistry
Department of Mineralogy, Petrography and Geochemistry is the oldest Earth science department at the AGH University of Science and Technology. It was created in 1919 as one of the first six departments of the Academy of Mining and was initially named as the Department of Mineralogy and Petrography. The Department was organized by Professor Józef Morozewicz (1865–1941) who chaired the Organizing...
متن کاملPetrography and Mineralogy of Dhofar 1428 Lunar Highland Regolith Breccia
Introduction: Dhofar 1428 is a lunar feldspathic breccia found in 2006. Bunch et al. [1] briefly described mineral chemistry of Dhofar 1428. Korotev and Zeigler [2] analyzed its bulk FeO and Sm compositions. Here, we report such detailed data for Dhofar 1428. Results and Discussion: Dhofar 1428 has a distinct breccia texture with numerous fragments of rock, mineral, and glass all welded by a gl...
