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 …

It is commonly assumed that the building blocks of the terrestrial planets were derived from a
cosmochemical reservoir that is best represented by chondrites, the so-called chondritic …

Dust is a ubiquitous feature of the cosmos, im**ing directly or indirectly on most fields of
