All chondrites accreted∼ 3.5 wt.% C in their matrices, the bulk of which was in a
macromolecular solvent and acid insoluble organic material (IOM). Similar material to IOM is …

This brief overview comments on recent trends in scientific research and development of
clay minerals and was stimulated by the compilation of papers for this special issue to pay …

Abiotic hydrocarbons and carboxylic acids are known to be formed on Earth, notably during
the hydrothermal alteration of mantle rocks. Although the abiotic formation of amino acids …

The search for traces of life is one of the principal objectives of Mars exploration. Central to
this objective is the concept of habitability, the set of conditions that allows the appearance …

Numerous descriptions of organic molecules present in the Murchison meteorite have
improved our understanding of the early interstellar chemistry that operated at or just before …

Organic compounds occur in some chondritic meteorites, and their signatures on solar
system bodies have been sought for decades. Spectral signatures of organics have not …

In the Earth's lithosphere, fungi are of fundamental importance as decomposer organisms,
animal and plant pathogens and symbionts (eg lichens and mycorrhizas), being ubiquitous …

We have analyzed the chemically and isotopically well‐characterized insoluble organic
matter (IOM) extracted from 51 unequilibrated chondrites (8 CR, 9 CM, 1 CI, 3 ungrouped C …

Chondrites accreted the oldest solid materials in the solar system including dust processed
in the protoplanetary disk and diverse organic compounds. After accretion, asteroidal …

This article reviews progress in the understanding of the role of clay minerals in crude oil
formation, migration and accumulation. Clay minerals are involved in the formation of …
