The matrix of a carbonaceous chondrite is the background "sea' in which the chondrules, inclusions and larger mineral grains occur. It is finely comminuted material which mainly comprises the anhydrous phases of meteorites, such as olivine, pyroxene, and Fe/Ni metal, together with lesser amounts of Fe oxides and sulphides, carbonates, sulphates, and a variety of other minerals. There is much interest in the matrix because it contains information about the early history and development of the carbonaceous chondrites, and provides a model for studying alteration processes in the early solar system. The paper describes the morphology and general characteristics of the matrix, and reviews the classification and chemistry of carbonaceous chondrites. It then discusses matrix mineralogy of the various types of carbonaceous chondrite, before considering alteration processes. -after Authors
