Asteroid 2008 TC3, not a polymict ureilitic but a polymict C1 chondrite parent body? Survey of 249 Almahata Sitta fragments
Bischoff, Addi; Bannemann, Lukas; Decker, Stephan; Ebert, Samuel; Haberer, Siegfried; Heitmann, Ursula; Horstmann, Marian; Klemm, Kerstin I.; Kraemer, Ann‐Kathrin; Lentfort, Sarah; Patzek, Markus; Storz, Jakob; Weyrauch, Mona (Meteoritics & Planetary Science, 2022-05-14)On October 7, 2008, the asteroid 2008 TC3 exploded as it entered the Earth’s atmosphere, producing significant dust (in the atmosphere) and delivering thousands of stones in a strewn field in Sudan, collectively known as ... -
Classification of CM chondrite breccias—Implications for the evaluation of samples from the OSIRIS-REx and Hayabusa 2 missions
Lentfort, Sarah; Bischoff, Addi; Ebert, Samuel; Patzek, Markus (Meteoritics & Planetary Science, 2020)CM chondrites are complex impact (mostly regolith) breccias, in which lithic clasts show various degrees of aqueous alteration. Here, we investigated the degree of alteration of individual clasts within 19 different CM ... -
Experimentally Induced Thermal Fatigue on Lunar and Eucrite Meteorites—Influence of the Mineralogy on Rock Breakdown
Thermal fatigue has been proven to be of fundamental importance for the nature and evolution of surfaces of airless bodies in the solar system. It is a rock erosive process acting in conjunction with meteoroid bombardment. ... -
Hf-W chronology of a macrochondrule from the L5/6 chondrite Northwest Africa 8192
Hellmann, Jan L.; Kruijer, Thomas S.; Metzler, Knut; Patzek, Markus; Pack, Andreas; Berndt, Jasper; Kleine, Thorsten (Meteoritics & Planetary Science, 2020)A large, igneous-textured, and 2 cm-sized spherical object from the L5/6 chondrite NWA 8192 was investigated for its chemical composition, petrography, O isotopic composition, and Hf-W chronology. The petrography and ... -
The chondrite breccia of Antonin (L4‐5)—A new meteorite fall from Poland with a heterogeneous distribution of metal
Bischoff, Addi; Patzek, Markus; Peters, Stefan T. M.; Barrat, Jean‐Alix; Di Rocco, Tommaso; Pack, Andreas; Ebert, Samuel; Jansen, Christian A.; Kmieciak, Kryspin (Meteoritics & Planetary Science, 2022-08-23)On July 15, 2021, a huge fireball was visible over Poland. After the possible strewn field was calculated, the first and so far only sample, with a mass of 350 g, was discovered 18 days after the fireball event. The Antonin ... -
The polymict carbonaceous breccia Aguas Zarcas: A potential analog to samples being returned by the OSIRIS‐REx and Hayabusa2 missions
Kerraouch, Imene; Bischoff, Addi; Zolensky, Michael E.; Pack, Andreas; Patzek, Markus; Hanna, Romy D.; Fries, Marc D.; Harries, Dennis; Kebukawa, Yoko; Le, Loan; Ito, Motoo; Rahman, Zia (Meteoritics & Planetary Science, 2021-02-02)On April 23, 2019, a meteorite fall occurred in Aguas Zarcas, Costa Rica. According to the Meteoritical Bulletin, Aguas Zarcas is a brecciated CM2 chondrite dominated by two lithologies. Our X‐ray computed tomography (XCT) ...
