This Record presents new Sensitive High Resolution Ion Micro Probe (SHRIMP) U–Pb geochronological results for five drill core samples from the Rover mineral field, an area of... -
New SHRIMP U-Pb zircon ages from the Georgetown and Coen regions,...
New Sensitive High Resolution Ion Microprobe (SHRIMP) U–Pb geochronological results for six samples are presented in this Record. The samples are from cores of basement units... -
Effect of chemical abrasion of zircon on SHRIMP U-Pb, d180O, Trace element,...
This study assesses the effect of chemical abrasion on in-situ mass spectrometric isotopic and elemental analyses in zircon. Chemical abrasion improves the U-Pb systematics of... -
A slab origin for low-δ18O arc magmas
Plate tectonics is the primary method for cycling of material between the mantle, crust, and surface reservoirs of our planet. Oxygen isotopes (18O/16O, δ18O) in zircon have... -
Timing and significance of pre-Olarian metamorphism in the Willyama...
In the Willyama Supergroup of the Curnamona Province, the intensity of granulite facies Olarian metamorphism at c. 1600 Ma has long hampered efforts to elucidate the timing and... -
Zircon O and Lu-Hf isotopes in Tasmanian Devonian Granites
The Tasmanian Devonian granites were emplaced during the Tabberabberan Orogeny when the East and West Tasmania Terranes collided. The primary aim of this study is to determine... -
Insights to the evolution of the Thomson Orogen from geochronology,...
Zircon U-Pb ages, εHf(t) and δ18O isotopic data, geochemistry and limited Sm-Nd results mostly from deep basement drill cores from undercover parts of the Thomson Orogen,... -
From discordance to discovery: extracting fluid-rock interaction timescales...
Zircon remains a preferred mineral for uranium-lead (U-Pb) geochronology due to its chemical durability. Despite its robustness, zircon is susceptible to isotopic modifications... -
