CA,AL-RICH INCLUSIONS, AMOEBOID OLIVINE AGGREGATES, AND AL-RICH CHONDRULES FROM THE UNIQUE CARBONACEOUS CHONDRITE ACFER 094: I. MINERALOGY AND PETROLOGY

Krot A.N.; Keil K.; Fagan T.J.; Yurimoto H.; McKeegan K.D.; Sahijpal S.; Hutcheon I.D.; Petaev M.I. (2004)

Based on their mineralogy and petrography, ~200 refractory inclusions studied in the unique carbonaceous chondrite, Acfer 094, can be divided into corundum-rich (0.5%), hibonite-rich (1.1%), grossite-rich (8.5%), compact ...
EVALUATION OF 26AL/27AL AT CRYSTALLIZATION IN EFREMOVKA CAIS BY HIGH-PRECISION, IN SITU ION MICROPROBE ANALYSES

McKeegan K.D.; Taylor D.J.; Krot A.N.; Sahijpal S.; Ulyanov A.A. (2004)

Estimates of the initial “canonical” (~5 10 -5) value of 26Al/27Al in the solar nebula are based primarily on ion microprobe analyses of high Al/Mg phases in CAIs. Some of these minerals (e.g., plagioclase, melilite) are ...
ION MICROPROBE STUDIES OF EFREMOVKA CAIS: II. POTASSIUM ISOTOPE COMPOSITION AND 41CA IN THE EARLY SOLAR SYSTEM

Srinivasan G.; Sahijpal S.; Goswami J.N.; Ulyanov A.A. (1996)

The potassium isotope composition of refractory phases in Efremovka CAIs has been measured by an ion microprobe. Extensive studies of terrestrial standards were carried out to ensure that the experimental procedures adopted ...
K, MG, TI AND CA ISOTOPIC COMPOSITIONS AND REFRACTORY TRACE ELEMENT ABUNDANCES IN HIBONITES FROM CM AND CV METEORITES: IMPLICATIONS FOR EARLY SOLAR SYSTEM PROCESSES

Sahijpal S.; Goswami J.N.; Davis A.M. (2000)

Potassium and magnesium isotopic compositions of hibonites from the Murchison (CM) and Allende (CV) meteorites are determined by an ion microprobe to look for possible presence of the short-lived nuclides 41Ca and 26Al at ...
