Time plays a crucial role in Earth science. Geochronological information is vital for establishing when Earth processes occur, how long they last, and their rates of change, becoming ever more necessary for contemporary, cross-disciplinary Earth science investigations. Geochronology is advancing quickly as current techniques gain precision and finer spatial resolution, while innovative methods emerge. There's an increasing need for researchers capable of evaluating geochronological data's advantages and constraints while accurately analyzing such information.
The Department of Geological Sciences boasts faculty with varied geochronology specializations, alongside laboratories where students can practice sample preparation for dating analysis, collect measurement data, and interpret chronological datasets. Key GEOL facilities feature the (U-Th)/He Geochronology Lab (CU TRaIL) led by Professor Becky Flowers, equipped with an Alphachron He extraction system and Agilent 7900 quadrupole ICPMS, plus the Electron Microprobe lab housing a new JEOL 8230 probe for mineral analysis and monazite U-Pb dating under Professor Kevin Mahan. INSTAAR resources include the Cosmogenic Preparation Lab overseen by Professors Bob Anderson and Giff Miller, the ICPMS lab with a Thermo Finnigan Element2 sector field ICP-MS managed by Professor Tom Marchitto, and the Amino Acid Geochronology lab featuring two Agilent HPLCs, directed by Professor Giff Miller. Additional mineral analysis support comes from GEOL's Raman spectroscopy equipment.
