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.

Chondrites and Their Components
Edward Scott,Alexander N. Krot +1 more
TL;DR: In this article, the properties of carbonaceous, ordinary and enstatite chondrites focusing on the most pristine samples are reviewed to establish the chemical, isotopic, and mineralogical properties and origins of their components and to elucidate the asteroidal processes that modified them.

U-Pb chronology of the Solar System's oldest solids with variable 238 U/ 235 U
Yuri Amelin,Angela Kaltenbach,Tsuyoshi Iizuka,Claudine H. Stirling,Trevor Ireland,Michail I. Petaev,Stein B. Jacobsen +6 more
TL;DR: In this article, the authors presented the first combined high-precision U and Pb isotopic data for a CAI, and U isotope data for chondrules and whole rock fractions of the Allende meteorite.

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.

Molybdenum isotope anomalies in meteorites: Constraints on solar nebula evolution and origin of the Earth
Christoph Burkhardt,Thorsten Kleine,Thorsten Kleine,Felix Oberli,Andreas Pack,Bernard Bourdon,Bernard Bourdon,Rainer Wieler +7 more
TL;DR: The early evolution of the solar nebula involved substantial transport of mass, resulting in mixing and homogenization of isotopically diverse materials that were contributed to the solar system from multiple stellar nucleosynthetic sources as mentioned in this paper.

Treatise on geochemistry
TL;DR: This extensively updated new edition of the widely acclaimed Treatise on Geochemistry has increased its coverage beyond the wide range of geochemical subject areas in the first edition, with five new volumes which include: the history of the atmosphere, geochemistry of mineral deposits, archaeology and anthropology, organic geochemistry and analytical geochemistry as discussed by the authors.

TL;DR: It is reported that boulders can undergo efficient gravitational collapse in locally overdense regions in the midplane of the disk, and it is found that gravitationally bound clusters form with masses comparable to dwarf planets and containing a distribution of boulder sizes.
