Oligocene-Miocene sedimentary record, eastern Taranki Basin margin

Abstract

A 2-day field trip departing 8am Thursday 29 November 2012 from Hamilton south to Te Kuiti-Piopio-Awakino-Tongaporutu affords a fine north to south transect through examples of the Mesozoic to Quaternary succession in the Waikato-King Country region bordering the eastern margin of Taranaki Basin. The trip will view some of the onshore Oliocene and Miocene sedimentary record in the Waikato and King Country basins and comment on how this links into the offshore parts of eastern Taranaki Basin. Primarily under both local and more distant tectonic control, we will track the various carbonate and terrigenous (locally volcaniclastic)-dominated facies associated with marginal marine, shoreline, shelf and slope-to-basin depositional settings, and consider their stratigraphic architecture and wider sequence stratigraphic context. Visits are planned along the way to basement greywacke, serpentinite and limestone quarries.
