Large Igneous Provinces of the Southern Hemisphere: Isotopic Geochemistry and Plagioclase and Pyroxene 40Ar/39Ar Geochronology of the Kalkarindji, Karoo and Ferrar Provinces
MetadataShow full item record
To develop a comprehensive understanding of geological processes a multidisciplinary approach must be utilized. This PhD research contributes to the understanding of Large Igneous Provinces (LIPs) petrogenesis through an integrated geochemical and high precision geochronological approach. This study integrates geochemical analyses and unprecedented high-precision and sensitive 40Ar/39Ar geochronology to continue to push various geochronological techniques and LIP research to new horizons.

Monazite trumps zircon: applying SHRIMP U–Pb geochronology to systematically evaluate emplacement ages of leucocratic, low-temperature granites in a complex Precambrian orogenPiechocka, A.; Gregory, C.; Zi, J.; Sheppard, S.; Wingate, M.; Rasmussen, Birger (2017)Although zircon is the most widely used geochronometer to determine the crystallisation ages of granites, it can be unreliable for low-temperature melts because they may not crystallise new zircon. For leucocratic granites ...

Dating sedimentary rocks using in situ U-Pb geochronology of syneruptive zircon in ash-fall tuffs <1 mm thickRasmussen, Birger; Fletcher, Ian (2010)Absolute ages for sedimentary rocks are required to construct a temporal framework in which to decipher Earth's history. The most reliable method for dating Precambrian sedimentary rocks is U-Pb geochronology of zircon ...
