Ph.D. student Tihana Pensa completed two months of laboratory work at the Andalusian Institute of Earth Sciences in Granda, Spain, under the direction of Dr. Antonio Delgado Huertas. 

Tihana visited the Centre for Scientific Instrumentation at the University of Granada equipped with a new state-of-the-art TIMS (mass spectrometry with thermal ionization source) machine. 

She analyzed Sr, O, C, and S isotopes on rock samples from the Red Sea basin to determine the age and environments of deposition.
