40Ar/39Ar ages of alkali feldspar xenocrysts constrain the timing of intraplate basaltic volcanism
TLDR
In this article, entrained anorthoclase megacrysts were used to yield 40Ar/39Ar ages for scoria cones and maars from the Pliocene-Holocene Newer Volcanic Province (NVP) of south-eastern Australia.About:

Early human occupation of southeastern Australia: New insights from 40Ar/39Ar dating of young volcanoes
TL;DR: In this article, the authors focused on two monogenetic volcanoes in the Newer Volcanic Province of southeastern Australia: Budj Bim and Tower Hill, respectively.

Evidence of a common source component for east Australian Cenozoic mafic magmatism
TL;DR: In this article, an extensive database of new and previous major element, trace element, and radiogenic isotope data and principal component analysis from key volcanic exposures in Queensland and New South Wales was used to find no systematic geochemical differences between the two groups.
Journal ArticleDOI
An evidence-based approach to accurate interpretation of 40Ar/39Ar ages from basaltic rocks
TL;DR: In this article, the authors present 40 Ar/ 39 Ar step-heating data for multiple samples from two Quaternary basalt flows (0.8038 ± 0.0017 and 2.309 ± 0.009 Ma) of the intraplate Newer Volcanic Province, southeast Australia.

TL;DR: McDougall et al. as mentioned in this paper derived intercalibration factors for McClure Mountain hornblende (MMhb-1), GHC-305 biotite, GA-1550, Taylor Creek sanidine (TCs), relative to Fish Canyon sanidine(ACs), were derived from 797 analyses involving 11 separate irradiations with well-constrained neutronfluence variations.
