The abundances of tungsten in 17 chondrites, 6 achondrites, 5 siderites, one sample of meteoritic olivine, one sample of meteoritic troilite, 5 types of tektites, one meteoritic impact glass, 3 obsidians, 4 samples of a deepsea sediment core, and 2 standard rocks were determined by means of neutron activation analysis. A cosmic atomic abundance for tungsten of 0.11 (Si = 10/sup 6/) was calculated on the basis of the chondrite analyses. Information on the geochemical distribution of tungsten in separated meteoritic phases and certain terrestrial rocks was obtained. Some implications of the data of theories of nucleosynthesis and meteorite formation are discussed. (auth)
