NTGS NTGS has an ongoing geochronology and isotope geochemistry program, supporting NTGS regional geoscientific investigations and mapping projects across the Territory.
NTGS, with our collaborators, undertake a range of analyses, including: Sensitive High Resolution Ion Microprobe (SHRIMP) and Laser Ablation Inductively Coupled Plasma Mass Spectrometry (LA-ICPMS) U-Pb zircon and monazite geochronology, LA-ICPMS in situ garnet rare earth element (REE) analysis and Hf zircon isotopic analysis, SHRIMP and Secondary Ion Mass Spectrometry (SIMS) O zircon isotopic analysis and Sm-Nd whole-rock and mineral isotopic analysis using Multi-Collector Inductively Coupled Plasma Mass Spectrometry (MC-ICPMS).
Undertaking these types of studies allows NTGS geologists to understand the timing and nature of geological processes important to the geological evolution of the Northern Territory.
