When magmas erupt at the surface, they may have undergone many changes since their inception. While olivine drives some of these changes through crystallization and fractionation, it also records the magma evolution via mineral chemistry and by trapping mineral and melt inclusions. Olivine is an effective recorder of intensive parameters, such as temperature and melt composition, and provides an outstanding petrological tool for constraining dynamic processes, such as ascent, mixing, and cooling. Olivine sheds light on magmatic puzzles that involve both mafic and more evolved magmas, with protracted and complex magmatic histories that often obscure earlier and deeper processes. This contribution summarizes the current state of how olivine helps reconstruct source-to-surface magma assembly through its chemistry, inclusions, and textures.

Olivine occurs across the galaxy, from Earth to extraterrestrial bodies including the Moon, Mars, and asteroids, to particles of comet dust and distant debris disks. The mineral is critical to our understanding of early Solar System chronology, planetary formation processes (e.g., magma ocean solidification), crustal evolution (e.g., volcanic eruptions), and surface weathering. Olivine’s ability to shed light on these processes lies in the linkage of small, physical samples and satellite-derived data. Laboratory spectra become the basis for olivine detection and compositional interpretation in remotely sensed spectra ranging from high-resolution planetary maps to single extra-solar datapoints. In turn, petrologic studies of olivine underpin the geologic interpretations of these spectral datasets. Finally, olivine chemistry records Solar System formation conditions and relative chronology. Olivine is our bridge across time and space.

Primitive achondrites are a remarkable family of meteorites, marking the transition between unmolten chondrites and fully differentiated achondrites (Fig. 1). As such, these meteorites sampled partially melted planetesimals, formed only a few million years (My) after the formation of the first solids in the Solar System. Primitive achondrites have coarse-grained igneous achondritic textures, resulting from extensive thermal metamorphism, while retaining some chondritic features such as relict chondrules and chondritic bulk rock compositions (Krot et al. 2014). The peculiar nature of primitive achondrites constrains their parent body petrogenesis, which is yet to be fully understood. Primitive achondrites are subdivided into different groups on the basis of their petrologies and chemical and isotopic compositions, including the acapulcoites–lodranites, winonaites, brachinites, and ureilites (Krot et al. 2014). While brachinites and ureilites have very distinctive petrologic characteristics, the boundary between winonaites and acapulcoites is not so obvious. In fact, the similarities between winonaites and acapulcoites may have been hiding an entirely new class of primitive achondrites (Stephant et al. 2023).
