Journal ArticleDOI
The Absolute Chronology and Thermal Processing of Solids in the Solar Protoplanetary Disk
James N. Connelly,Martin Bizzarro,Alexander N. Krot,Åke Nordlund,Daniel Wielandt,Marina A. Ivanova +5 more
TL;DR: U-corrected Pb-Pb dating from primitive meteorites indicates that chondrule formation started contemporaneously with CAIs and lasted ~3 million years, suggesting that the formation ofCAIs and chondrules reflects a process intrinsically linked to the secular evolution of accretionary disks.
Journal ArticleDOI
Evidence for magnesium isotope heterogeneity in the solar protoplanetary disk
K. K. Larsen,Anne Trinquier,Chad Paton,Martin Schiller,D. Wielandt,Marina A. Ivanova,James N. Connelly,Åke Nordlund,Alexander N. Krot,Martin Bizzarro +9 more
TL;DR: In this article, the authors report high-precision Mg-isotope measurements of inner solar system solids, asteroids, and planets demonstrating the existence of widespread heterogeneity in the mass independent 26Mg composition (μ26Mg*) of bulk solar system reservoirs with solar or near-solar Al/Mg ratios.
Journal ArticleDOI
L-chondrite asteroid breakup tied to Ordovician meteorite shower by multiple isochron 40Ar-39Ar dating
Ekaterina V. Korochantseva,Mario Trieloff,C. A. Lorenz,Alexey I. Buykin,Marina A. Ivanova,Winfried H. Schwarz,Jens Hopp,Elmar K. Jessberger +7 more
TL;DR: This paper reported the discovery of multiple 40Ar-39Ar isochrons in L chondrites, particularly the regolith breccia Ghubara, that allow the separation of radiogenic argon from multiple excess argon components.
Journal ArticleDOI
Martian meteorite Dhofar 019: A new shergottite
Lawrence A. Taylor,M. A. Nazarov,M. A. Nazarov,C. K. Shearer,Harry Y. McSween,Joshua T.S. Cahill,Clive R. Neal,Marina A. Ivanova,L. D. Barsukova,R. C. F. Lentz,Robert N. Clayton,Toshiko K. Mayeda +11 more
TL;DR: Dhofar 019 as mentioned in this paper is a basaltic shergottite that was found in the desert of Oman, and is classified as a Basaltic Shergottites.
Journal ArticleDOI
The Isheyevo meteorite: Mineralogy, petrology, bulk chemistry, oxygen, nitrogen, carbon isotopic compositions, and 40Ar‐39Ar ages
Marina A. Ivanova,N. N. Kononkova,Alexander N. Krot,Richard C. Greenwood,Ian A. Franchi,A. B. Verchovsky,Mario Trieloff,Ekaterina V. Korochantseva,Franz Brandstätter +8 more
TL;DR: Isheyevo is a metal-rich carbonaceous chondrite that contains several lithologies with different abundances of Fe,Ni metal (7-90 vol%). as discussed by the authors showed that the metalrich and metal-poor lithologies are most similar to the CBb and CH carbonized chondrites, respectively.
