Volcanic eruptions that are <1 Ma are significant for geological and archaeological investigations, however these eruptions can be challenging to date. Zircon double-dating (ZDD) is one of the few techniques that can be used to date young volcanic rocks, and combines the (U-Th)/He method with individual zircon crystallisation ages to yield eruption ages. This thesis presents several methodological improvements to the ZDD methodology and applies it to two case studies.

Danisik, Martin (2019)Fission-track (FT) thermochronology can be integrated with the U–Pb and (U–Th)/He dating methods. All three radiometric dating methods can be applied to single crystals (hereafter referred to as “triple-dating”), allowing ...
Late Miocene (U+Th)-4He ages of ferruginous nodules from lateritic duricrust, Darling Range, Western AustraliaPidgeon, Robert; Brander, T.; Lippolt, H. (2004)(U+Th)-4He dates are presented for hematite/maghemite and hematite separates from pisolitic nodules from four rock specimens of lateritic duricrust sampled in an area of about 1 km2 in the Darling Range about 50 km northeast ...
Jourdan, Fred (2012)The 40Ar/39Ar technique is a powerful geochronological method derived from the K/Ar technique that can help to unravel the evolution of the solar system. The 40Ar/39Ar system can not only record the timing of volcanic and ...
