“…The thin‐bedded, low‐density turbidity current deposits (Lf1) of FA1 could represent either downslope or lateral equivalents of thick‐bedded (Lf3) deposits, which perhaps initiated further from the study site, or could be products of initially smaller, low‐density flows. The increasing prominence of Lf3b deposits up‐section is consistent with the interfingering transition from dominantly Mohakatino Formation to dominantly Mount Messenger Formation deposits through time (Masalimova et al ., ). However, the presence of a thick‐bedded deposit of terrigenous sediment near the middle of section I (Fig.…”

“…The less thickly‐bedded and more erosive nature (Fig. I and J) of the Lf3b deposits in this area relative to the northern part of the study area suggests that these deposits represent a bypass‐dominated, channelized region of the Mount Messenger Formation system, which is consistent with the interpretation of a channelized lobe complex directly up‐section of these deposits (Masalimova et al ., ).…”

“…Recent studies also show that some of the igneous bodies in the southern part of the MVC may have been intrusive only, without associated volcanic edifices, and probably post‐dated Mohakatino Formation deposition by 5 Myr or more (Luke, ; Cammans, ). However, some degree of confinement is likely to have been present along the south‐western margin, considering the strong northward transport of Mount Messenger Formation sediments despite the regional slope orientation toward the west (Strogen et al ., ; Rotzien et al ., ; Masalimova et al ., ). This could perhaps be attributed to sediment doming over intrusive igneous suites in advance of volcano development, but precise dating of intrusions is difficult from seismic reflection imagery alone, without direct sampling of the materials.…”

“…The change in thickness is consistent with, and can perhaps be entirely explained by, the loss of thick‐bedded Lf3a deposits toward the south, from more proximal to more distal positions on the submarine lobe. This southward thinning could signal a change of accommodation toward the south, with sediments onlapping a topographic feature (for example, the northward‐prograding channel‐lobe system of the Mount Messenger Formation; Masalimova et al ., ), or could simply reflect thinning of deposits with increasing distance from the volcanic source area.…”

Submarine volcanoes produce sediment that originates and remains in a deep-water setting, never escaping the water column. This situation puts a twist on the idea of 'source to sink' pathways, where both source and sink are in the submarine realm. Submarine volcanoes may play a significant role in basin sedimentation and evolution, but direct observation of sediment production and dispersal from submerged volcanoes is logistically difficult. This study analyzes the Mohakatino Formation, a Miocene deep-marine unit produced by ancient submarine volcanoes of the Taranaki Basin, New Zealand, to investigate sediment transport and deposition from these volcanoes. Outcrop analysis of the volcanogenic deposits suggests a submarine lobe environment in a north-south elongated sub-basin, confined by the growing volcanic arc to the north and west and a fault-controlled topographic high to the east. Composition and sedimentary structures indicate that most deposits in this area are reworked volcanogenic material, rather than primary deposits from individual eruption events, transported to the depocentre by eruptioninitiated and mass wasting-initiated turbidity currents. This study highlights the need for submarine volcanoes to be considered in source to sink investigations, to ascertain their role as sediment sources to marine basins. Deeply submerged volcanoes are disconnected from some environmental signals, while sedimentation from shallow-water volcanoes may be especially sensitive to perturbations in sea-level and climate. In both cases, a short transfer zone between source and sink may increase the likelihood that source area signals are transmitted to the sedimentary record.

“…The architecture and evolution of deep-water channel systems has been of particular interest in both the hydrocarbon industry and academic study in recent years with detailed investigations using highresolution reflection seismic data sets (e.g., McHargue and Webb, 1986;Badalini et al, 2000;Babonneau et al, 2002Babonneau et al, , 2004Abreu et al, 2003;Deptuck et al, 2003Deptuck et al, , 2007Posamentier, 2003;Posamentier and Kolla, 2003;Schwenk et al, 2005;Mayall et al, 2006;Kolla, 2007;Cross et al, 2009;Catterall et al, 2010;Armitage et al, 2012;Jobe et al, 2015;Ortiz-Karpf et al, 2015) and seabed imaging techniques (e.g., Torres et al, 1997;Maier et al, 2011Maier et al, , 2013Covault et al, 2014), although these provide limited detailed information on subseismic-scale elements and the range and distribution of sedimentary facies. This gap has been addressed through the use of analogous systems at outcrops (Badescu et al, 2000;Blikeng and Fugelli, 2000;Campion et al, 2000;Clark and Gardiner, 2000;Gardner et al, 2003;Beaubouef, 2004;Pickering and Corregidor, 2005;Hodgson et al, 2011;Brunt et al, 2013b;Hubbard et al, 2014;Masalimova et al, 2016). Although these studies help to constrain the distribution and lateral variation of sedimentary facies of channel fills, channel-scale stacking patterns, and detailed stratigraphic relationship with adjacent levee-overbank deposits, they typically have limited three-dimensional (3-D) control or calibration with subsurface data sets.…”

The morphological evolution of submarine channel systems can be documented using high-resolution three-dimensional seismic data sets. However, these studies provide limited information on the distribution of sedimentary facies within channel fills, channelscale stacking patterns, or the detailed stratigraphic relationship with adjacent levee-overbank deposits. Seismic-scale outcrops of unit C2 in the Permian Fort Brown Formation, Karoo Basin, South Africa, on two subparallel fold limbs comprise thin-bedded successions, interpreted as external levee deposits, which are adjacent to channel complexes, with constituent channels filled with thick-bedded structureless sandstones, thinner-bedded channel margin facies, and internal levee deposits. Research boreholes intersect all these deposits, to link sedimentary facies and channel stacking patterns identified in core and on image logs and detailed outcrop correlation panels. Key characteristics, including depth of erosion, stacking patterns, and cross-cutting relationships, have been constrained, allowing paleogeographic reconstruction of six channel complexes in a 36-km 2 (14-mi 2 ) area. The system evolved from an early, deeply incised channel complex, through a series of external levee-confined and laterally stepping channel complexes culminating in an aggradational channel complex confined by both internal and external levees. Down-dip divergence of six channel complexes from the same location suggests the presence of a unique example of an exhumed deep-water avulsion node. Down-dip, external levees are supplied by flows that escaped from channel complexes of different ages and spatial positions and are partly confined and share affinities with internal levee successions. The absence of frontal lobes suggests that the channels remained in sand bypass mode immediately after avulsion.

The grain‐size distribution of sediment particles is an important aspect of the architecture of submarine fans and lobes. It governs depositional sand quality and reflects distribution of particulate organic carbon and pollutants. Documenting the grain‐size distribution of these deep‐marine sedimentary bodies can also offer us an insight into the flows that deposited them. Submarine lobes are commonly assumed to linearly fine from an apex, meaning there should be a proportional relationship between grain size and distance from the lobe apex. However, not much detailed quantitative work has been done to test this hypothesis. Exposure of a 5 km long dip‐section of basin‐floor lobes in Clinoform 12, Battfjellet Formation, Spitsbergen, enable the study of basinward grain‐size evolution in lobe deposits. Furthermore, the dataset allows testing if there are any documentable grain‐size differences between lobe sub‐environments. For this purpose, the palaeogeography of Clinoform 12 was reconstructed and the youngest lobe, which was exposed in all collected logs, chosen to be evaluated for its grain‐size trends. Photographed thin sections of 66 rock samples were analysed to obtain quantitative grain‐size distributions. The results show that fining of lobe deposits occurs predominantly in the most proximal and most distal parts of the lobe, while the intermediate lobe, which is dominated by lobe off‐axis deposits, is characterised by a relatively consistent grain‐size range. Lobe sub‐environments show statistically distinct grain‐size distributions from lobe axis to lobe fringe. An explanation for these trends is the interplay of capacity and competence‐driven deposition with the grain‐size stratification of the flows. The outcomes of this study help to better understand the proximal to distal evolution of turbidity currents and their depositional patterns. They also provide important insights in reservoir potential of basin‐floor fans at lobe scale.
