Pahvant Butte, an isolated volcano that erupted in an arm of Lake Bonneville, is an outstanding example of the product of an emergent eruption, its interaction with water-level, erosion and deposition during eruption, and the volcano's response to post-eruptive water-level changes.
ABSTRACT The Cagayan basin of Northern Luzon, an interarc basin 250 km long and 80 km wide, contains a 900 m thick sequence of Plio-Pleistocene fluvial and pyroclastic deposits. These deposits are divided into two formations, the Ilagan and Awidon Mesa, and three lithofacies associations. The facies, which are interpreted as meandering stream, …
lated with volcaniclastic deposits, which are interpreted to be depos-ited in lacustrine environments (Gihm & Hwang, 2014). 4 | LITHOLOGIC AND DEPOSITIONAL CHARACTERISTICS OF THE DAERI MEMBER The Daeri Member is composed of a variety of volcanic and volcaniclastic rocks as well as siliciclastic rocks. In this study, …
The Bunga Beds outlier of the Upper Devonian Boyd Volcanic Complex, south-eastern Australia, preserves a shallow- to relatively deep-water terrigenous sedimentary rock succession, associated syn-depositional rhyolites, minor basalts, and a variety of volcaniclastic facies, all interpreted to have formed in an extensional lake basin.
On 2–3 January 1996 an explosive eruption discharging ≈ 10 6 kg s −1 of basaltic magma occurred in Karymskoye lake at an initial water depth of ≈ 50 m. Characteristics of the deposits together with analyses of a videotape of several explosions have allowed us to model the eruptive events.
The role of volcanism in the production and transport of great volumes of sediments across sedimentary systems needs to be carefully re-examined, and the analysis on the variability in the composition of volcaniclastic deposits must take into account that volcaniclastic particle types may not simply reflect a linear deepening in the dissection ...
This volume presents a unique compendium of papers assessing the effects of volcanism on lakes, as recorded by the volcaniclastic sediments deposited within them. The unifying theme is that the effects of volcanism on lacustrine sedimentation are diverse and distinctive, and that volcaniclastic lacustrine sediments hold the key to understanding a …
volcaniclastic sedimentation can also be modulated by changes in the physiography and accommodation of the receiving basins induced by contemporaneous tectonic activities, …
Pumice is an unusual geological material. It is of low density, its density can vary, reversibly, through time, and it is capable of floating in water. These properties result directly from the abund...

The eruption of Taupo caldera, New Zealand, c. 1.8 ka, climaxed in the emplacement of the Taupo ignimbrite, which dammed the previous outlet of the caldera lake and allowed rise of the lake behind the dam to c. 34 m above current lake level.After an estimated 20 yrs of lake refilling, the ignimbrite dam was breached, and the lake drained rapidly to a position …
He presents a new model for the ways in which glacial hydrology affects impoundment of intraglacial lakes and the resulting drainage pathways (see also Smellie, 2000a). …

An ≈ 1.1 km-thick succession of middle Eocene strata from the upper Sanpoil Volcanics and lower Klondike Mountain Formation in the Republic Basin, Okanogan Highlands, northern Washington, records the transition from active volcanism and hydrothermal activity to dominantly lacustrine sedimentation in a highly extended region.
Research into delta-front patch reefs from Borneo and fore-arc carbonate platform development from Java is described and used to evaluate the effects of siliciclastic and volcaniclastic influx on regional carbonate sedimentation, local changes in carbonate-producing biota and sequence development.
Pahvant Butte, an isolated volcano that erupted in an arm of Lake Bonneville, is an outstanding example of the product of an emergent eruption, its interaction with water‐level, erosion and deposition during eruption, and the volcano's response to post‐eruptive water‐level changes.

Pyroclastic fire fountaining and phreatomagmatic activity can generate buoyant eruption columns, modulating the altitude of gas injection. Both phreatomagmatic and lava-water activity can produce large volumes of permeable, glass-rich, mafic volcaniclastic material. These mafic volcaniclastic deposits (MVDs) are prone to reaction and alteration.

The emplacement of a voluminous ignimbrite at the climax of the 1.8 ka Taupo eruption buried an area of ≈ 20 000 km 2 in the central North Island of New Zealand. Infilling of valleys and the blockage of drainages by pyroclastic material destroyed hydrological networks and allowed the development of numerous temporary supra …

ABSTRACT In active tectonic areas of humid equatorial regions, nearshore shallow-water environments are commonly sites of near-continuous siliciclastic influx and/or punctuated volcaniclastic input. Despite significant clastic influence, Neogene carbonates developed in SE Asia adjacent to major deltas or volcanic arcs, and are comparable with …
The cataclysmic eruption of Mount Mazama, Oregon, at c. 6730 14 C yr BP, deposited tephra over 1.0 × 10 6 km 2 of north-western North America. Primary tephra fall accumulated to a thickness of 2 cm in the upper Skagit River watershed, Washington.
