A 4,565-My-old andesite from an extinct chondritic protoplanet.

Proc Natl Acad Sci U S A 2021 Mar 8;118(11). Epub 2021 Mar 8.

Université de Lorraine, CNRS, CRPG, F-54000 Nancy, France.

The age of iron meteorites implies that accretion of protoplanets began during the first millions of years of the solar system. Due to the heat generated by Al decay, many early protoplanets were fully differentiated with an igneous crust produced during the cooling of a magma ocean and the segregation at depth of a metallic core. The formation and nature of the primordial crust generated during the early stages of melting is poorly understood, due in part to the scarcity of available samples. Read More
