AN INTEGRATED MINERALOGICAL, PETROGRAPHIC, LIGHT STABLE ISOTOPE AND NOBLE GAS INVESTIGATION OF SAHARA 99201 UREILITE. C. L. Smith

New ureilite Sahara 99201 has been investigated to determine mineralogy, petrography, light stable isotopes and noble gases. The sample is a typical olivine pigeonite ureilite (Fo 78, Wo 10, En 72). C, N, O and Ar are consistent with other ureilites.
