The Extended Jaeger 5 bldg
The chemistry and isotope chemistry of natural materials is highly indicative of provenance and process throughout geological history. Our studies range in time from the earliest solar system through to processes that are actively taking place today, and in scope from planetary systems to individual molecules. Active areas of research centre on planetary studies, metamorphic and igneous geochemistry and geochronology, geochemistry of life processes, and chronology of all processes encompassed.
The J5 building extension was completed in 2008. The project involved doubling the length of the extant building and adding a second floor to house offices, a seminar room (The D. H. Green Room), and geochemistry laboratories. Starting in July, SHRIMP II was moved from J3 to its new position in the J5 SHRIMP building and is now operational again. Construction of SHRIMP SI has now recommenced and is proceeding well with expectations of testing in mid 2009. The fit out of the J5 chemistry laboratories is underway with installation of extraction hoods nearly complete. These laboratories will be established under the direction of Dr Yuri Amelin. The completion of the office space upstairs sees a focal point for the Planetary Science Institute at RSES.
Inside the new lab.
Dr Stewart Fallon joined Earth Chemistry in 2008. In January 2009, Dr Vickie Bennett will be taking leave of absence from RSES to take up a position at Johnson Space Center, Houston. The SHRIMP team, comprising Dr John Foster, Dr Peter Holden, Mr Peter Lanc, Mr Ben Jenkins, and Mr Norm Schram, received a Vice Chancellor's Award for Innovation and Excellence in Service Quality for 2008.
PhD studies were completed by Diane Valente, Courtney
Gregory, and Joe Hiess. Congratulations Doctors.
