Abstract: We are investigating the effects of thermal meta-morphism on crystalline and amorphous silicates in the matrices of CO carbonaceous chondrites, which range in petrologic type from 3.0 to 3.8. Our aim is to better understand the initial formation conditions of the sili-cates, and to quantify how the degree of asteroidal heating has influenced their abundance, structure, chemistry and transformation behaviour. Here we pre-sent results from the CO chondrites DOM 08006 (CO 3.0), Kainsaz (CO 3.2) and Moss (CO 3.6).
