The age of the Solar System can be defined as the time of formation of the first solid grains in the nebular disc surrounding the proto-Sun. This age is estimated by dating calcium‐aluminium-rich inclusions in meteorites. These inclusions are considered as the earliest formed solids in the solar nebula. Their formation marks the beginning for several longand short-lived radiogenic clocks that are used to precisely define the timescales of Solar System events, such as the formation and evolution… 

Evidence for the late formation of hydrous asteroids from young meteoritic carbonates.

It is concluded that hydrous asteroids accreted later than differentiated and metamorphosed asteroids, and the young carbonate age suggests the late onset of aqueous activities in the Solar System.

Primitive Solar System materials and Earth share a common initial 142Nd abundance

It is found that CAIs without isotopic anomalies in Nd compared to the terrestrial composition share a 146Sm/144Sm–142Nd/144Nd isotopic evolution with Earth, which supports a chondritic Sm/Nd ratio for the bulk silicate Earth and, as a consequence, chondrite abundances for other refractory elements.

A Perspective from Extinct Radionuclides on a Young Stellar Object: The Sun and Its Accretion Disk

Meteorites, which are remnants of solar system formation, provide a direct glimpse into the dynamics and evolution of a young stellar object (YSO), namely our Sun. Much of our knowledge about the

Dating the Oldest Rocks and Minerals in the Solar System

Meteorites originating from asteroids are the oldest-known rocks in the Solar System, and many predate formation of the planets. Refractory inclusions in primitive chondrites are the oldest-known

Correlated accretion ages and ε54Cr of meteorite parent bodies and the evolution of the solar nebula

We look at the relationship between the value of ε54Cr in bulk meteorites and the time (after calcium‐aluminum‐rich inclusion, CAI) when their parent bodies accreted. To obtain accretion ages of



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

Homogeneous Distribution of 26Al in the Solar System from the Mg Isotopic Composition of Chondrules

Micrometer-scale, high-precision magnesium (Mg) isotopic analyses demonstrate that Earth, refractory inclusions, and chondrules from primitive meteorites formed from a reservoir in which short-lived aluminum-26 (26Al) and Mg isotopes were homogeneously distributed at ±10%.

Mg isotope evidence for contemporaneous formation of chondrules and refractory inclusions

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.

Extremely Brief Formation Interval for Refractory Inclusions and Uniform Distribution of 26Al in the Early Solar System

Calcium-aluminum-rich inclusions (CAIs) are millimeter-sized refractory objects commonly found in chondritic meteorites and are the oldest solids formed in our solar system. Primary CAI formation may

60Fe in Chondrites: Debris from a Nearby Supernova in the Early Solar System?

60Fe decays to 60Ni with a half-life of 1.49 × 106 yr, so all of the original 60Fe atoms incorporated into the solar system have decayed. Because 60Fe is produced only in stars, its initial abundance

Correlated Iron 60, Nickel 62, and Zirconium 96 in Refractory Inclusions and the Origin of the Solar System

We report precise nickel isotopic compositions, measured with high-resolution MC-ICPMS, for calcium-aluminum-rich inclusions (CAIs) considered to be the earliest objects formed in the solar system.

Chronology of the early Solar System from chondrule-bearing calcium-aluminium-rich inclusions

It is reported that relict chondrule material in the Allende meteorite, composed of olivine and low-calcium pyroxene, occurs in the outer portions of two CAIs and is 16O-poor, contrary to the presence of relict CAIs inside chondrules, as well as to the higher abundance of 26Al in CAIs.

238U/235U Variations in Meteorites: Extant 247Cm and Implications for Pb-Pb Dating

High-resolution mass spectrometry shows that the known starting abundance of 238U and 235U isotopes in meteorites, which decay into 206Pb and 207Pb, respectively, is actually quite variable, suggesting that Pb-Pb dating, the method commonly used to date early solar system materials, may need a correction of up to 5 million years.
