Angrites are among the oldest known pristine basaltic meteorites and record the earliest stages of planet formation and differentiation. Our paleomagnetic analysis of three angrites found that they record a past magnetic field of ∼10 microteslas on the angrite parent body extending from 4564 to at least 4558 million years ago. Because the angrite paleomagnetic record extends beyond the expected lifetime of the early circumstellar disk, these paleofields were probably generated internally on the… 

Magnetic Mineralogy of Meteoritic Metal: Paleomagnetic Evidencefor Dynamo Activity on Differentiated Planetesimals

Many meteorite parent bodies experienced large-scale melting due to heating from short-lived radionuclides during the early solar system, leading to differentiation and the formation of a metallic

Paleomagnetic Records of Meteorites and Early Planetesimal Differentiation

The large-scale compositional structures of planets are primarily established during early global differentiation. Advances in analytical geochemistry, the increasing diversity of extraterrestrial

Magnetic meteorites and the early solar system

Today, the Earth generates a magnetic field through convection of the electrically conducting molten iron in its outer core. Core convection is governed by the thermal and chemical processes that

Persistence and origin of the lunar core dynamo

Analysis of two 3.56-Gy-old mare basalts demonstrating that they were magnetized in a stable and surprisingly intense dynamo magnetic field of at least ∼13 μT extend the known lifetime of the lunar dynamo by ∼160 My and indicate that the field was likely continuously active until well after the final large basin-forming impact.

A Long‐Lived Planetesimal Dynamo Powered by Core Crystallization

The existence of numerous iron meteorite groups indicates that some planetesimals underwent melting that led to metal‐silicate segregation, sometimes producing metallic cores. Meteorite paleomagnetic

Magnetic evidence for a partially differentiated carbonaceous chondrite parent body

The textures of chondritic meteorites demonstrate that they are not the products of planetary melting processes. This has long been interpreted as evidence that chondrite parent bodies never

Differentiated Planetesimals and the Parent Bodies of Chondrites

Meteorites are samples of dozens of small planetary bodies that formed in the early Solar System. They exhibit great petrologic diversity, ranging from primordial accretional aggregates (chondrites),

Decline of the lunar core dynamo




Widespread magma oceans on asteroidal bodies in the early Solar System

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.

A model for planetesimal meltdown by 26Al and its implications for meteorite parent bodies

Abstract— The melting of planetesimals heated by 26Al has been modelled using a new finite difference method that incorporates convection. As an example, we consider a planetesimal with a radius of
