Scientific paper

Bulk chemical analyses of six E-type chondrites are given. The chondrites include Daniel's kuil, Khairpur, Kota Kota, and Sain Sauveur, together with South Oman, and St. Mark's chondrites. The distribution of lithophile elements between silicate and sulfide mineral groups was measured using selective attack by dry chlorine on magnetically separated fractions. Subdivision of the E-chondrites into types I and II is shown using chemical data for the St. Mark's and Saint Sauveur chondrites. It is found that the Sulphides contributed the largest proportion of elements to the bulk composition; the proportion of Ti contributed to the bulk composition by the sulfides in both chondrite types increased in relation to the intensity of the thermal metamorphic effect. A complete list of the chemical abundances in the chondrites is provided.
