About WassoniteHide

Specific Gravity:
4.452 (Calculated)
Crystal System:
Named in honor of John Taylor Wasson (b.1934), professor, University of California Los Angeles (UCLA) in the Departments of Chemistry and Biochemistry, and Earth and Space Sciences. He developed methods to use neutron activation data to classify iron meteorites and chondritic meteorites and to formulate models for the observed chemical fractionations in bulk chondrites. He also investigated potential mechanisms for forming tektites.
