Context.The cooling history of individual meteorites can be reconstructed if closure temperatures and closure ages of different radioisotopic chronometers are available for a couple of meteorites. If a close similarity in chemical and isotopic composition suggests a common origin from the same parent body, some basic properties of this body can be derived.Aims.The radius of the L chondrite parent body, its formation time, and its evolution history are determined by fitting theoretical models to… 

Uncertainties in physical properties of Itokawa-like asteroids widen constraints on their formation time

One of the outstanding questions in planetary science is to determine how the fundamental mechanical and physical properties of materials determine the thermal evolution of asteroids, and which

Early formation of primitive achondrites in an outer region of the protoplanetary disc

We compare 13 Tafassasset-related meteorites and propose that they form the first meteorite group of carbonaceous primitive achondrites. We name this new group the Tafassites, which form a continuum

Chirality in Organic and Mineral Systems: A Review of Reactivity and Alteration Processes Relevant to Prebiotic Chemistry and Life Detection Missions

The properties oforganic compounds and minerals as well as the physical, chemical, and geological processes that affect organic and mineral chirality during the preservation and detection of organic compounds are reviewed.

Impact dynamics of the L chondrites' parent asteroid

The dynamics of collisional events have been studied for three highly shocked L chondrites (Tenham, Sixiangkou, and Acfer 040). Crystal growth rates of high‐pressure polymorphs of olivines and

New Evidence for Wet Accretion of Inner Solar System Planetesimals from Meteorites Chelyabinsk and Benenitra

We investigated the hydrogen isotopic compositions and water contents of pyroxenes in two recent ordinary chondrite falls, namely, Chelyabinsk (2013 fall) and Benenitra (2018 fall), and compared them

Evolution of the parent body of enstatite (EL) chondrites

Systematic investigations of high‐pressure polymorphs in shocked ordinary chondrites

Shock‐induced melting textures and high‐pressure polymorphs in 178 ordinary chondrites of all chemical groups and petrologic types were investigated. The shock‐induced melting modes were classified



Petrology and geochemistry of Patuxent Range 91501, a clast‐poor impact melt from the L‐chondrite parent body and Lewis Cliff 88663, an L7 chondrite

Abstract— We have performed petrologic and geochemical studies of Patuxent Range (PAT) 91501 and Lewis Cliff (LEW) 88663. PAT 91501, originally classified as an L7 chondrite, is rather a unique, near
