“…Based on this evidence, we interpreted the cone apron to contain fine-grained layers of tephra transported by subaqueous eruption plumes, likely interbedded with reworked material from cone collapses and degradation, a phenomena commonly observed in volcanoes elsewhere (e.g. White, 1996;Kereszturi and Németh, 2013;Pope et al, 2018). The cone apron likely contains minor subaqueous lavas that overspill from the crater rim (and possible peperitic material associated with invasive lavas and/or shallow type-4…”

“…chaotic reflectors, sediment waves) that could indicate reworking of parts of the volcanic edifices during eruptions. Cas et al, 1989;Fiske et al, 1998;Corcoran and Moore, 2008;Pope et al, 2018). On the cone apron of a cone-type volcano of the MVS (Figure 19), seismic images show a characteristic facies that resembles sediment waves occurring between the PrErS and PoErS horizons, which may represent syn-eruptive submarine landslides such as those reported by Pope et al (2018).…”

“…Sedimentological and volcanological processes observed on modern volcanoes (e.g. White, 1991;Cas and Wright, 1992;Chadweck et al, 2012;Kereszturi and Németh, 2013;Pope et al, 2018) suggest that the syn-eruptive interval of the MVS may comprise sedimentary deposits triggered by simultaneous eruptions, together with primary volcanic eruptive deposits. Processes related to the eruptions such as earthquake shockwave, explosions, and magmatic inflation are potential triggers for debris flows, submarine landslides and cone-sector collapses (e.g.…”

Large volumes of magma emplaced and deposited within sedimentary basins can have an impact on their architectural style and geological evolution. Over the last decade, continuous improvement in techniques such as seismic volcano-stratigraphy and 3D seismic visualization of igneous rocks buried in sedimentary basins has helped increase knowledge about these “volcanic basins”. Here, we unravel the complete architecture of the Maahunui Volcanic System (MVS), a middle Miocene monogenetic volcanic field now buried in the offshore Canterbury Basin, South Island of New Zealand. We show the location, geometry, size, and stratigraphic relationships between 25 main intrusive, eruptive, and sedimentary architectural elements in a comprehensive volcano-stratigraphic framework that explains the evolution of the MVS from emplacement to complete burial. The plumbing system of the MVS comprises of seven main architectural elements, including saucer-shaped sills, dikes and sills swarms, minor stocks and laccoliths, and pre-eruptive strata deformed by intrusions. These endogenous elements occur in five distinctive plumbing-types, controlled by the emplacement depth, and by the geometric relationships between the intrusions and the enclosing strata. The exogenous volcanic architecture is defined by a combination of eruptive and associated sedimentary architectural elements, with minor and localized shallow intrusions. Characteristic volcano-types of the MVS are interpreted as the deep-water equivalents of crater and cone-type volcanoes. Crater-type volcanoes have eight main architectural elements (i.e. root zone, lower and upper diatreme, tephra ring, tephra plain, intra-crater cones, overspill wedge and tephra fallow carpet). Cone-type volcanoes have five main architectural elements (i.e. basal cone, central crater, tephra flank, cone apron and tephra fallout carpet). After volcanism has ceased, the process of degradation and burial of the volcanic edifices produces five main sedimentary architectural elements (i.e. inter-cone plains, epiclastic plumes, canyons and gullies, burial domes and seamount-edge fans). Understanding the relationships between these diverse architectural elements allow us to reconstruct the complete architecture of the MVS, and to recognize the main volcano-stratigraphic trends in the study area. The characterisation of architectural elements of the MVS can be applied to explore opportunities to find valuable geoenergy resources such as oil, gas and geothermal energy with buried and active monogenetic volcanic systems.

“…Seismic interpretation suggests that the HSF may be interpreted as the morphological expression of the submarine counterpart of pyroclastic flow and surge deposits of the Vesuvian Eruption of 79 CE (unit 4) that entered the seawater after the destroying of Herculaneum (MILIA et al 2008, POPE et al 2018. Particularly, the massive, homogeneous texture of the coarse grained pumice, lapilli and ash of unit 4 may result from the underwater modification of primary pyroclastic currents into turbulent flows (FREUNDT 2003, LE FRIANT et al 2009, TROFIMOVS et al 2012, JUTZELER et al 2017, POPE et al 2018, SLOOTMAN et al 2019 and references therein).…”

Very high-resolution, single channel (IKB-Seistec™) reflection profiles acquired offshore the Napoli Bay, complemented with geological and geophysical data from the literature, provide unprecedented, superb seismic imaging of the Latest Pleistocene-Holocene stratigraphic architecture of the submerged sectors Campi Flegrei and Somma-Vesuvius volcanic districts. Seismic profiles were calibrated by gravity core data and document a range of depositional systems, volcanic structures and hydrothermal features that evolved after the onset of the Last Glacial Maximum (ca. 18 ka BP) over the continental shelf on the Campania coastal zone.Seistec profiles from the Pozzuoli Bay yield high-resolution images of the shallow structure of the collapse caldera-ring fault - resurgent dome system associated with the eruption of the Neapolitan Yellow Tuff (NYT) (ca 15 ka BP) and support a working hypothesis to assess the timing and the styles of deformation of the NYT resurgent structure throughout the Latest Quaternary. Seismic images also revealed the nature of the fragile deformation of strata along the NYT ring fault system and the occurrence of hydrothermal fluids and volcanic/sub-volcanic intrusions ascending along the ring fault zone. Seismic data acquired over the continental shelf off the Somma-Vesuvius stratovolcano, display evidence of gravitational instability of sand wave deposits originated by the underwater modification of pyroclastic flows that entered the seawater after destroying the Roman city of Herculaneum during the 79 CE eruption of Vesuvius.At the Banco della Montagna, a hummocky seafloor knoll located between the Somma-Vesuvius and the Pozzuoli Bay, seismic profiles and gravity core data revealed the occurrence of a field of volcaniclastic diapirs formed by the dragging and rising up of unconsolidated pumice, as a consequence of fluid overpressure at depth associated with active degassing and fluid venting at the seafloor.

増田富士雄 1＊・服部昇 2 ・石田志朗 3 Supercritical-flow sedimentary structures of fluvial deposits in the Plio-Pleistocene Katata Formation, Kobiwako Group, Japan Fujio Masuda 1＊ , Noboru Hattori 2 and Shiro Ishida 3Sedimentary structures related to supercritical-flows, including antidunes, chutes-and-pools and cyclic steps, have been identified from fluvial flood deposits in the Plio-Pleistocene Katata Formation, Kobiwako Group, Shiga, Japan. The characteristics of sedimentary structures by high-energy flood flows are 1) backset laminae and backstepping lamina sets with up-stream migration, 2) sigmoidal, wavy and HCS-mimics laminae, 3) scour and fill gravel, sand and mud, 4) cyclically scoured erosional bases, and 5) mixed beds with heterolithic and well and poorly sorted deposits. The observed sedimentary structures considered as supercritical-flow deposits have high diversity. The deposits with much mud-content show fast sedimentation rate from the supercritical-flows contained large amount of suspended mud. We have to observe furthermore the sedimentary structures linked to supercritical-flow bedforms from deposits of various ages, areas and depositional environments.
