Research Technician III, Geosciences

This Research Technician III, Geosciences position is with University of Arizona in Tucson, AZ. Preparation of geological samples for isotopic analysis: Mounting detrital zircon and other accessory minerals using an optical microscope. Polishing sample mounts and acquire optical images. Involves cleaning of equipment thoroughly between samples to avoid any contamination is a significant component to this position. Ordering sample mounting and preparation supplies as needed. Monitoring, tracking, and recording ALC user samples as they move through the entire process from zircon extraction, mounting, SEM imaging, and isotopic analysis. This will involve corresponding with visiting researchers to ensure we are on-track for their session, and that their samples are ready to analyze. Performing mineral separation in a laboratory setting, including but not limited to Frantz magnetic separations, ultrasonic bath operation, heavy liquid separations, Wig-L-Bug separations, acid washing samples, and mounting samples. Use of personal protective equipment (e.g. safety glasses, laboratory coat, nitrile gloves, engineered ventilation hood system, etc.) required. Assist with the operation of scanning electron microscope (SEM) and/or mass spectrometers/excimer laser systems to acquire geochronologic and/or geochemical data for the Arizona LaserChron Center researchers. Perform basic data reduction using in-house MATLAB protocols to evaluate quality of data. Training students and visiting researchers on how to mount, polish, and image samples. Knowledge, Skills, and Abilities (KSAs): Knowledge of U-Pb geochronology, especially as it pertains to detrital zircon geochronology. Knowledge of the operation of mass spectrometer, excimer laser, and scanning electron microscope (SEM). Ability to follow laboratory safety protocols and maintain a clean work environment to prevent sample contamination. Ability to accurately track, organize, and document samples and laboratory records. Ability to communicate effectively with students, researchers, and visiting scientists.
