“…Earthquake-triggered turbidites may in some cases be distinguished from those resulting from non-earthquake disturbances using sedimentological criteria (Nakajima and Kanai, 2000;Shiki et al, 1996Shiki et al, , 2000aPouderoux et al, 2012). Earthquake-triggered density flows are created when shaking causes subaqueous failures and sediment entrainment producing a dense, sediment-laden flow which is transported downslope to the site of deposition.…”

Abstract. Here we investigate sedimentary records from four small inland lakes located in the southern Cascadia forearc region for evidence of earthquakes. Three of these lakes are in the Klamath Mountains near the Oregon-California border, and one is in the central Oregon Coast range. The sedimentary sequences recovered from these lakes are composed of normal lake sediment interbedded with disturbance event layers. The thickest of these layers are graded, and appear to be turbidites or linked debrites (turbidites with a basal debris-flow deposit), suggesting rapid deposition. Variations in particle size and organic content of these layers are reflected in the density and magnetic susceptibility data. The frequency and timing of these events, based on radiocarbon ages from detrital organics, is similar to the offshore seismogenic turbidite record from trench and slope basin cores along the Cascadia margin. Stratigraphic correlation of these anomalous deposits based on radiocarbon ages, down-core density, and magnetic susceptibility data between lake and offshore records suggest synchronous triggering. The areal extent and multiple depositional environments over which these events appear to correlate suggest that these deposits were most likely caused by shaking during great Cascadia earthquakes.

“…Hence, the preserved event record has formed in response to a number of drivers of varying frequency and magnitude. Lake Tutira is ~100 km downwind of the active TVZ and this close proximity led to the preservation of twelve discrete air-fall tephras in the lake sediments Page et al, 2010), and some form important chronostratigraphic markers in the adjacent marine sequence (e.g., Gomez et al, 2007;Gerber et al, 2010;Pouderoux et al, 2012b). Lake tephra deposits have been used previously, along with other age markers (e.g., pollen, diatoms, radiocarbon and 137 Cs activity), to establish the late-Holocene sedimentation history (e.g., Page and Trustrum, 1997;Eden and Page, 1998).…”

“…Seventy-six percent of the 18-ky sequence in the giant piston cores is composed of cm-thick turbidites alternating with hemipelagites, tephras and debrites, at an average rate of 5.5 turbidites per meter (Pouderoux et al, 2012b). For example, the Paritu Trough shows a relatively coarse interval (average of 5.5 phi, solid vertical black bar) and high textural variability before ~13 ka (Fig.…”

A fundamental goal of the Earth Science community is to understand how perturbations on Earth's surface are preserved in the stratigraphic record. Recent Source to Sink (S2S) studies of the Waipaoa Sedimentary System (WSS), New Zealand, are synthesized herein to provide a holistic perspective of the processes that generate, transport and preserve sedimentary strata and organic carbon on the Waipaoa margin in the late Quaternary. Rapid uplift associated with subduction processes and weak sedimentary units have conspired to generate rapid rates of incision and erosion in the Waipaoa catchment since the Last Glacial Maximum (LGM). We show that although much of the sediment exported offshore during this time interval originated from valley excavation, a substantial portion emanated from hillslopes, mostly through deep-seated landslide and earthflow processes that were vigorous during periods of rapid fluvial incision just prior to the Pleistocene-Holocene transition. Lacustrine sediments deposited in naturally-dammed 7-ky-old Lake Tutira provide a record of Holocene environmental controls on upper catchment sedimentation in the WSS, with 1400 storms identified. Storm frequency is modulated by the waxing and waning of atmospheric teleconnections between the tropics and Antarctica. Furthermore, clear longterm changes in sediment yield are evident from the Lake Tutira record following humansettlement as conversion to pasture is accompanied by a 3-fold increase in the long-term lake sediment accumulation rate. Whereas there is ample evidence that Waipaoa River flood deposits are routinely deposited offshore in the sheltered confines of Poverty Bay, over the longer term, waves and currents subsequently resuspend and transport these deposits both landward (sandy fraction) and seaward (finer fraction). Thus, the timing of sediment supply to areas of net sediment accumulation is more often driven by wave events that are not associated with river flooding. Therefore, we conclude that asynchronicity of river-sediment delivery and of wave resuspension in most instances precludes the direct preservation of flood events in the stratigraphic record of the Waipaoa Shelf. Over the longer term, the sediment package preserved on the shelf and slope since the LGM can be explained in large measure by sequence-stratigraphic models forced by varying sea level and ongoing tectonic deformation of the margin. As sea level rose, sediment supply to the slope was reduced by about a factor of 5 due to shelf trapping. Despite this reduction, turbidites are found at similar frequency throughout the LGM-Present, as the dominant trigger appears to be subduction earthquakes, with large ones having a return interval of about 200 + 100 years. Sediment-budget exercises that consider both modern (river discharge versus centennial accumulation rates) and post-LGM (terrestrial production versus offshore isopachs) mass balances indicate that about half of the total sediment production from the Waipaoa escapes the study area. Moreover, a coupled sediment tra...

“…Of these deposits, sandy-debris-flow and turbiditycurrent sandstones have good reservoir properties and the closest association with oil and gas. The relation between turbidites and sandy debris flows is rather complex and cannot be explained by the turbidite flow model (Shanmugam 1996;Pouderoux et al 2012;Mulder et al 1997;Haughton et al 2009;Sumner et al 2012;Migeon et al Kane and Pontén 2012). Previous studies mainly focused on the macroscopic properties and models of sandy-debris-flow and turbidity-current sandstones.…”

Deep-water deposition is a current issue in sedimentological research. Sandy-debris-flow sandstones and turbidity-current sandstones are the main types of sandstone that are the focus of considerable disputes in this research. Previous studies mainly focused on description of the macroscopic sedimentary structure and theoretical derivation of the formation mechanisms. The microscopic petrological characteristics, reservoir properties, and formation mechanisms of deep-water sandy-debris-flow and turbidity-current sandstones have been studied in the Yanchang Formation of the Ordos Basin, China, by means of field outcrop surveys, thin-section identification, geochemical element analysis, and porosity and permeability measurements under overburden pressure. The content of detrital grains in the sandy-debris-flow sandstones is high, whereas the contents of mica sheets and matrix are low. The fine-grained matrix is distributed unevenly within the pores. A considerable number of residual intergranular pores are preserved in the middle of single sand bodies, resulting in relatively better reservoir properties. The total number of detrital grains in the turbidite sandstone is low, while it contains abundant mica sheets and matrix. The mica sheets and fine-grained matrix are distributed evenly within the pores, resulting in serious damage to pores and poor reservoir properties. The sandy-debris-flow sandstones in the center of the lake basin form a high-quality reservoir; thus, this area is suitable for oil and gas exploration.
