In situ oxygen isotope compositions in olivines of different types of cosmic spherules: An assessment of relationships to chondritic particles
Rudraswami, N.G.; ShyamPrasad, M.; Jones, R.H.; Nagashima, K. (Elsevier, 2016)Cosmic spherules collected from deep sea sediments of the Indian Ocean having different textures such as scoriaceous (4), relict-bearing (16), porphyritic (35) and barred olivine (2) were investigated for petrography, as ... -
Oxygen isotopic composition of relict olivine grains in cosmic spherules: Links to chondrules from carbonaceous chondrites
Rudraswami, N.G.; ShyamPrasad, M.; Nagashima, K.; Jones, R.H. (Elsevier, 2015)Most olivine relict grains in cosmic spherules selected for the present study are pristine and have not been disturbed during their atmospheric entry, thereby preserving their chemical, mineralogical and isotopic compositions. ...
