Dating the First Solids The solar system's first solids: calcium-aluminum–rich inclusions and chondrules are found in meteorites and provide a direct record of the dynamics of the solar protoplanetary disk that led to the formation of the solar system. Previous results indicate that chondrules formed 1 to 2 million years after the inclusions—an age difference that has been used in constructing models of chondrule formation. Based on uranium- and lead-isotope measurements of a collection of… 
Chondrules – ubiquitous chondritic solids tracking the evolution of the solar protoplanetary disk
Chondrite meteorites are samples of primitive asteroidal bodies that have escaped melting and differentiation. The only record of our Solar System’s formative stages comes from the earliest solids
Astronomical context of Solar System formation from molybdenum isotopes in meteorite inclusions
TLDR
It is proposed that CAIs formed while the Sun was in transition from the protostellar to pre–main sequence (T Tauri) phase of star formation, placing Solar System formation within an astronomical context.
Silicate–SiO reaction in a protoplanetary disk recorded by oxygen isotopes in chondrules
The formation of planetesimals and planetary embryos during the earliest stages of the solar protoplanetary disk largely determined the composition and structure of the terrestrial planets. Within a
Al amongst inner Solar System chondrules
Chondrites are fragments of asteroids that avoided melting and, thus, provide a record of the material that accreted to form protoplanets. The dominant constituent of chondrites are millimeter-sized
First evidence for silica condensation within the solar protoplanetary disk
TLDR
This AOA provides direct evidence that silica condensed from gas in a CAI/AOA-forming region in the early solar system and indicates that gas became Si-rich as Mg condensed and may explain the origin of silica detected from infrared spectroscopy of T Tauri and asymptotic giant branch stars.
Ca–Al-rich inclusions in carbonaceous chondrites: the oldest solar system objects
This paper presents a review of recent available data on the first solid condensates of the Solar System, which include refractory CAIs (Ca–Al-rich Inclusions) mostly composed of Ca, Al, Mg, and Ti
The first 200 kyr of the Solar System: making the planetary material diversity
Abstract Chondrites are made of a mixture of solids formed at high and low temperatures. This heterogeneity was thought to be produced by large scale transport processes in the Sun’s isolated
Early formation of planetary building blocks inferred from Pb isotopic ages of chondrules
TLDR
It is shown that primary production of chond rules in the early solar system was restricted to the first million years after the formation of the Sun and that these existing chondrules were recycled for the remaining lifetime of the protoplanetary disk.
The astrophysical context of collision processes in meteorites
Chondrites are leftover solids from the early evolution of the solar protoplanetary disk that never experienced melting since their formation. They comprise unequilibrated assemblages of low‐ and
Constraints on Chondrule Generation, Disk Dynamics, and Asteroid Accretion from the Compositions of Carbonaceous Meteorites
The elemental and isotopic compositions of meteorites are expected to reflect several key processes that occurred in the early solar system, including the migration of gas and dust throughout the

Chronology of the Solar System’s Oldest Solids
Determining the origins of our solar system and, by proxy, other planetary systems, depends on knowing accurately and precisely the timing and tempo of the transformation of the disk of gas and dust
Mg isotope evidence for contemporaneous formation of chondrules and refractory inclusions
TLDR
The presence of excess 26Mg resulting from in situ decay of the short-lived 26Al nuclide in CAIs and chondrules from the Allende meteorite is reported, indicating that Allende chondrule formation began contemporaneously with the formation of CAIs, and continued for at least 1.4 Myr.

Early planetesimal melting from an age of 4.5662 Gyr for differentiated meteorites
TLDR
The results indicate that the accretion of differentiated planetesimals pre-dated that of undifferentiated planetesIMals, and reveals the minimum Solar System age to be 4.5695 ± 0.0002 billion years.
Clumpy disk accretion and chondrule formation
Abstract Chondrules are the major constituent of most of the primitive meteorites, yet the mechanism of their formation is largely unknown. Chondrule textures and compositions place tight constraints
