Stratigraphy of a Basaltic Planetoid - 4 Vesta and the HEDs (original) (raw)

The paper discusses the stratigraphy of the basaltic planetoid 4 Vesta and the associated howardites, eucrites, and diogenites (HED meteorites), focusing on the sequence of geological events including accretion, differentiation, metamorphism, and impact events. It highlights the challenges in developing a comprehensive stratigraphic column due to limitations in sample size and the complexity of the geological history, while underscoring the importance of data from the Dawn mission to enhance understanding of Vesta's lithological diversity and stratigraphic evolution.
