New titanium isotope paper

Zack Torrano

In a new paper published in Geochimica et Cosmochimica Acta, PhD Candidate Zack Torrano and co-authors investigate whether the isotope compositions of previously analyzed calcium-aluminum-rich inclusions (CAIs) are representative of CAIs from other chondrites and chondrite groups and, by extension, the broader CAI-forming region in the solar nebula. CAIs are the oldest dated solids formed […]
