  author={Paul C. Froggatt and Campbell S. Nelson and L. Carter and Galen Griggs and Kerry P. Black},
A thick, widespread volcanic ash layer sampled from marine cores in the South Pacific and sub-Antarctic, has been identified using major and rare-earth element chemistry. It is the correlative of the airfall Mount Curl Tephra, the initial eruptive phase of the voluminous Whakamaru Ignimbrite from Taupo, New Zealand. Detailed oxygen-isotope analysis on the late Quaternary section of the core from Deep Sea Drilling Project Site 594, supplemented by other data, places Mount Curl Tephra within the… 

Deep‐ocean record of major late Cenozoic rhyolitic eruptions from New Zealand

Abstract A 12 m.y. record of large rhyolitic eruptions from the Coromandel (CVZ) and Taupo (TVZ) Volcanic Zones of New Zealand is contained in cores retrieved by Leg 181 of the Ocean Drilling

Composition of widespread volcanic glass in deep-sea sediments of the Southern Pacific Ocean: an Antarctic source inferred

Widespread Plio-Pleistocene (2.43-0.06 Ma) tephra zones recognised in deep-sea cores from high latitudes (>60°) in the Southern Pacific Ocean were thought to have originated from calc-alkaline

An Elemental and Isotopic Investigation of Quaternary Silicic Taupo Volcanic Zone Tephras from ODP Site 1123: Chronostratigraphic and Petrogenetic Applications

This thesis presents a chemical and isotopic investigation of well-dated silicic tephra layers sourced from the Taupo Volcanic Zone (TVZ), central North Island, New Zealand, that were recovered from

Late Quaternary tephrostratigraphy from the southern Havre Trough ‐ Bay of Plenty, northeast New Zealand

Abstract A number of late Quaternary subaerial silicic tephra erupted from the Taupo Volcanic Zone are dispersed at least 230 km to the northeast of New Zealand, and are deposited as predominantly



Atmospherically Transported Volcanic Glass in Deep-Sea Sediments: Volcanism in Sub-Antarctic Latitudes of the South Pacific During Late Pliocene and Pleistocene Time

Particulate separation and analysis of the fine fractions in nine dated deep-sea sedimentary cores, extending from high latitudes of the southwest to south-central Pacific, reveal very similar time

Mount Curl Tephra, a 230000-year-old implications for quaternary chronology marker bed in New Zealand, and its

Abstract The rhyolitic Mount Curl Tephra, probably erupted from the central region of the North Island of New Zealand, is inferred to be the product of a single major eruption, possibly associated

Late Quaternary marine stratigraphy southeast of New Zealand

Sediment cores of late Quaternary age from the continental margin and deep sea (Bounty Trough) southeast of New Zealand reveal an alternating sequence of glacial and interglacial sediments. During

Caldera Volcanoes of the Taupo Volcanic Zone, New Zealand

The Taupo volcanic zone (TVZ) has been active since 2 Ma and has erupted >104 km3 of dominantly rhyolitic magma during the last 1 m.y. Most of the volcanism is concentrated in a 125×60 km area

Near-synchroneity of New Zealand alpine glaciations and Northern Hemisphere continental glaciations during the past 750 kyr

The Brunhes magnetochron (0–730 kyr) at Deep Sea Drilling Project Site 594 off eastern South Island, New Zealand, comprises up to ∼100 m of alternating units of pelagic and hemipelagic ooze formed

Tephras in abyssal sediments east of the North Island, New Zealand: Chronology, paleowind velocity, and paleoexplosivity

Abstract In an earlier study, Ninkovich used paleomagnetic methods to date five mega-scopically distinguishable tephras in Pleistocene abyssal sediments east of the North Island, New Zealand. This

The exceptional magnitude and intensity of the Toba eruption, sumatra: An example of the use of deep-sea tephra layers as a geological tool

The eruption of Toba (75,000 years BP), Sumatra, is the largest magnitude eruption documented from the Quaternary. The eruption produced the largest-known caldera the dimensions of which are 100 × 30

Volcanic ash beds of the lower Waikato basin, North Island, New Zealand

Abstract This report describes volcanic ash beds that occur north of Otorohanga and west of Tirau in the central part of the North Island of New Zealand. The beds lie above one another as a mantle on
