SHRIMP monazite and zircon geochronology of high‐grade metamorphism in New Zealand

Journal of Metamorphic Geology, 1998
Ion microprobe dating of zircon and monazite from high‐grade gneisses has been used to (1) determine the timing of metamorphism in the Western Province of New Zealand, and (2) constrain the age of the protoliths from which the metamorphic rocks were derived.

Granitoid evolution in Sinai, Egypt, based on precise SHRIMP U–Pb zircon geochronology

Gondwana Research, 2009
Abstract Late-stage Pan-African granitoids, including monzogranite, syenogranite and alkali granite, were collected from four separate localities in Sinai. They were selected to represent both the calc-alkaline and alkaline suites that have been viewed as forming separate magmatic episodes in the Eastern Desert of Egypt, with the transition to alkali

SHRIMP U-Pb zircon geochronology of the Narryer Gneiss Complex, Western Australia

Precambrian Research, 1991
Abstract SHRIMP U-Pb zircon geochronology of the Narryer Gneiss Complex of the Yilgarn Craton, Australia, has confirmed that its eastern half contains abundant early Archaean gneisses (3300–3730 Ma), but has found gneisses with ages of only 3000 Ma or less in its western half.
