Vitric-rich volcaniclastic horizons are important for correlation of glacioeustatic sedimentary cycles, both within the well known shallow-marine record of Wanganui Basin, and other New Zealand terrestrial and deep marine records. They also record distal major rhyolitic eruptions from the Taupo (TVZ) and Coromandel (CVZ) Volcanic Zones that are lacking in proximal source areas. Twenty-eight volcaniclastic horizons are recognised in the Castlecliffian and late Nukumaruan strata of Wanganui Basin from glass shard major element geochemistry and stratigraphic position, and are dated using magnetostratigraphy, orbitally tuned cyclostratigraphy and isothermal plateau fission track (ITPFT) ages. The major named volcaniclastic horizons (with ITPFT and/or astronomical ages, respectively) are: Onepuhi (0.

“…Tephra layers buried in continental and marine deposits contain important information on the history and character of parent volcanic eruptions and their environmental impact (e.g. Rampino and Self, ; Alloway et al ., ; Timmreck, ; Guillet et al ., ). Studies of tephrostratigraphic records help with understanding the scale and recurrence rate of ancient explosive eruptions (e.g.…”

This paper presents the first detailed study of a late Pleistocene marine tephra sequence from the NW Pacific, downwind from the Kamchatka volcanic arc. Sediment core SO201-2-40, located on the Meiji Rise~400 km offshore the peninsula, includes 25 tephras deposited within the last 215 ka. Volcanic glass from the tephras was characterized using single-shard electron microprobe analysis and laser ablation inductively coupled mass spectrometry. The age of tephras was derived from a new age model based on paleomagnetic and paleoclimate studies. Geochemical correlation of distal tephras to Kamchatkan pyroclastic deposits allowed the identification of tephras from the Karymsky, Gorely, Opala and Shiveluch eruptive centers. Three of these tephras were also correlated to other marine and terrestrial sites and hence are identified as the best markers for the north-west Pacific region. These are an early Holocene tephra from the Karymsky caldera (~8.7 ka) and two tephras falling into the Marine Isotope Stage (MIS) 6 glacial time: an MIS 6.4 tephra from Shiveluch (~141 ka) and the MIS 6.5 Rauchua tephra (~175 ka) from Karymsky. The data presented in this study can be used in paleovolcanological and paleoceanographic reconstructions. recovered from core SO201-2-40 on the Meiji Rise (NW Pacific) (Fig. 1). The record includes 25 tephra layers and lenses deposited during the last~215 ka. We present an age model for the core based on paleomagnetic and stratigraphic

“…Reduced mean annual temperatures during the last glacial maximum (LGM) are known to have lowered equilibrium-line altitudes (ELAs) in New Zealand, causing glacial advances. Using a northward ELA gradient of 1.4 m/km, Shulmeister et al (2005) Alloway et al (2005) are included on the plot, as are selected data from Carter et al (1995). for Park Valley.…”

Geomorphologic and sedimentologic investigations in Park Valley, Tararua Range, have identified the presence of a lateral moraine toward the head of the valley. This section of Park Valley is U-shaped, southwest facing with the elongate ridge situated on the true right (northwestern) side of the valley. A variety of approaches is used to test the possible process origins of the ridge, including topographic and spatial positioning, sedimentology, and paleoclimatic extrapolations. Results indicate the ridge consists of glacial diamict deposited as a lateral moraine, supporting recent hypotheses about late Pleistocene glaciation and erosional development of valleys and cirques of this sector of the range.
