Wayne Premo

Wayne Premo is a Scientist Emeritus with the Geosciences and Environmental Change Science Center

Hired by the US Geological Survey in 1984, he worked first as the laboratory manager for Dr Mitsunobu Tatsumoto under the Upper Mantle Research Project within the USGS. At that time, he oversaw the work of many post-doc visitors to Tatsumoto's laboratories including Patrick E Smith (Toronto, Canada), Yoichi Nakamura (Utsunomiya, Japan), Jun-wen Wang (Guanghou, China), Asish Basu (U Rochester NY), Keiji Misawa (Kobe, NIPR, Tokyo, Japan), Marc Brouxel (Metz, France), C. Mark Fanning (ANU, Canberra, Australia), Holly Stein (Colorado State U), Noriko Kita (U Wisconsin) among others. Subsequently he did his first research on a variety of lunar samples, investigating the various Pb isotopic components of Moon rocks and later meteorites. He was promoted to research grade in 1993, continuing to work on lunar samples for the next 4 years, but adding terrestrial research to the palette. Among the many projects he was involved in over the next 20 years, a few standout: U-Pb zircon geochronology and Pb-Sr-Nd isotopic work on the Peninsular Ranges batholith, southern California; Age and origin of the Greens Creek Mine, Admiralty Island, Alaska; Pb-Sr studies of the MVT ore deposits of the Cevennes Region, southern France, U-Pb zircon geochronology and Pb-Sr-Nd isotopic work of the Proterozoic Colorado Province; and Age and origin of the Mountain Pass REE deposit, southern California.
