Mechanisms for the formation of crust on planetary bodies remain poorly understood. It is generally accepted that Earth’s andesitic continental crust is the product of plate tectonics, whereas the Moon acquired its feldspar-rich crust by way of plagioclase flotation in a magma ocean. Basaltic meteorites provide evidence that, like the terrestrial planets, some asteroids generated crust and underwent large-scale differentiation processes. Until now, however, no evolved felsic asteroidal crust… Expand
Non-basaltic asteroidal magmatism during the earliest stages of solar system evolution: A view from Antarctic achondrites Graves Nunatak 06128 and 06129
The recently recovered paired Antarctic achondrites Graves Nunatak 06128 and 06129 (GRA) are meteorites that represent unique high-temperature asteroidal processes that are identified in only a fewExpand
Trachyandesitic volcanism in the early Solar System
TLDR
Among the Almahata Sitta meteorites, a unique trachyandesite lava documents the presence of volatile- and SiO2-rich magmas on the UPB, which constrains the time of disruption of the body to later than 6.5 Ma after the formation of Ca–Al-rich inclusions. Expand
Alkali magmatism on a carbonaceous chondrite planetesimal
TLDR
This sample testifies of partial differentiation of outer Solar System carbonaceous planetesimals and can be considered as the long-sought first melt produced in differentiating small bodies, bridging a previously persistent gap in differentiation processes from icy cometary bodies to fully melted iron meteorites with isotopic affinities to carbonaceous chondrites.

A 4,565-My-old andesite from an extinct chondritic protoplanet
TLDR
EC 002 is, to date, the oldest known piece of an igneous crust with a 26Al-26Mg crystallization age of 4,565.0 million years (My), indicating that almost all of these bodies have disappeared, either because they went on to form the building blocks of larger bodies or planets or were simply destroyed. Expand
Silica-rich volcanism in the early solar system dated at 4.565 Ga
TLDR
Data on recently discovered volcanic meteorite Northwest Africa (NWA) 11119 is reported, which represents the first, and oldest, silica-rich (andesitic to dacitic) porphyritic extrusive crustal rock with an Al–Mg age of 4564.8 ± 0.3 Ma indicating that this is the earliest evidence of silicic volcanism in the Solar System to date.

Evidence for anorthositic crust formed on an inner solar system planetesimal
doi: 10.7185/geochemlet.1921 During the first million years of solar system history, planetesimals experienced extensive melting powered by the radioactive decay of 26Al (Lee et al., 1977). To date,Expand
More Evidence for Multiple Meteorite Magmas
Cosmochemists have identified six main compositional types of magma that formed inside asteroids during the first 100 million years of Solar System history. These magmas vary in their chemical andExpand

Abstract The paired achondrites Graves Nunataks (GRA) 06128 and 06129 are samples of an asteroid that underwent partial melting within a few million years after the start of Solar System formation.Expand
Linking asteroids and meteorites to the primordial planetesimal population
Abstract Meteorites provide a unique insight into early Solar System processes. However, to fully interpret this record requires that these meteorites are related back to their source asteroids andExpand

Widespread magma oceans on asteroidal bodies in the early Solar System
TLDR
It is shown that magma oceans were present on all the differentiated Solar System bodies so far sampled, and the modification of such bodies before incorporation into larger objects can explain some anomalous planetary features, such as Earth's high Mg/Si ratio. Expand
Evidence from detrital zircons for the existence of continental crust and oceans on the Earth 4.4 Gyr ago
TLDR
The discovery of a detrital zircon with an age as old as 4,404 ± 8 Myr is reported, about 130 million years older than any previously identified on Earth and represents the earliest evidence for continental crust and oceans on the Earth. Expand
