Further Development and Testing of the Combined U-Thdisequilibrium/ U-Pb and (U-Th)/He Zircon Dating Method and its Application to Quaternary Volcanic Rocks
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 ind...

| Summary: | 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. |
