The mineral was named after John T. Wasson, a professor at the University of California, Los Angeles and was approved by the International Mineralogical Association.[5][6] References1. ^1 Mindat.org {{Sulfide-mineral-stub}}2. ^[https://www.mineralienatlas.de/lexikon/index.php/MineralData?mineral=Wassonite Mineralienatlas] 3. ^{{cite web|title=Scientists Find New Type Of Mineral In Historic Meteorite|url=http://www.nasa.gov/home/hqnews/2011/apr/HQ_11-098_New_Mineral.html|publisher=NASA|accessdate=2011-04-07|author1=Dwayne C.
