... is covered 90% by till and peat deposits, and 5% by sand, together with gravel. Boulder fields cover about 4% of the study area, and exposed bedrock the remainder ( Johansson and Kujansuu 2005 ). Glacial till is the most common type of surficial sediment in the study area, due to the multiple glaciation...

... peat. V S30 values at seismic stations lacking measured V S data are assigned using a locally calibrated peat-thickness proxy-based model ( Buckreis, 2022 ) where peat-thickness is taken from nearby borings or cone penetration tests (CPTs), or is estimated using the approach of Deverel...

... in the main Agassiz basin based on projected water planes (the The Pas to Ponton). Radiocarbon dating on basal wood remains of surface peat in a former strait defined by the Ponton shoreline and a nearby site on the former lake floor indicates the abandonment of this shoreline and hence the withdrawal of Lake...

... transport by channelized flows. Extensive presettlement and postsettlement units of massive, organic-poor, fine-grained sediment formed when overbank flows inundated floodplains. Peat deposits, exposed at a single site (but absent elsewhere), represent a presettlement wetland. Decimeter-thick, discontinuous...

... industrialization, mechanisms governing the atmospheric Hg cycle in preindustrial periods remain unclear. Alpine peatlands receive Hg mainly from atmospheric Hg deposition and are sensitive to climatic changes, therefore alpine peat cores can be a useful archive for understanding the relationship between...

... of south Lincolnshire have high susceptibility to ground movement due to the underlying geology. Deposits such as peat, tidal flat deposits and alluvium have a high susceptibility to compress, particularly when loaded or through loss of water content driven by climate change or lowering of water...

.... [calibrated] yr B.P. onward), when the modern ENSO regime was established ( Mariani et al., 2017 ). Our study documented millennial- and centennial-scale shifts in vegetation and plant-specific isotopic compositions in a peat bog located in southernmost Patagonia, in a zone that is highly sensitive to changes...

... is depicted in red lines. The blocks in black or white have non-physical Poisson ratio values. The data were acquired in a field close to Pijnacker, Netherlands. The available well data ( Fig. 16 ) show that the field consists of clay, peat, and sand. The source was a vibrator that emitted...

... in a northerly direction. A chronology obtained through optically stimulated luminescence (OSL) dating spans from c. 29 ka for sands and clays at an elevation of −0.66 mOD to surface windblown sands at <300 years, at an elevation of 8.45 mOD. A basal peat, dated by radiocarbon dating to the early Holocene...

...-West2 and NGA-Subduction projects. The lowest V S 30 values in these histograms are in the range of 100–200 m/s. As a result, the application of ergodic models to soft peat sites represents an extrapolation beyond the data range—the ergodic mean site response is simply unknown. Figure 1...

... Basin, eastern Australia. We also document little-transported fossil charcoal occurrences in middle to late Permian (Guadalupian to Lopingian) permineralized peats of the Lambert Graben, East Antarctica, and Sydney and Bowen basins, eastern Australia, indicating that even vegetation of consistently...

Miroshnichenko Abstract —Two cores of the Dulikha peat bog deposits, 4.0 and 5.2 m thick, were studied in detail. The reduction type of diagenesis has been established. Decomposition of the organic matter...

..., and paleoecological analyses from a peat sequence in the Falkland Islands, South Atlantic Ocean, to describe changes in the SHWW between 16.0 and 6.5 ka (thousands of years before CE 1950). Wind strength was low at ~51°S before and during the Antarctic Cold Reversal (ACR, 14.9–13.0 ka), intensified between 13.1...

... for the BD, W, and SiO 2bio records and about 200 years for other parameters. Fig. 6. Summary plot of selected records from the Lake Engarginskoe sediments. 1 , biogenic silt with diatoms; 2 , clayey silt; 3 , fine sand; 4 , peat; 5 , fine sand with plant fragments; 6 , position of dated levels...

... sedimentary environments (peat, lake, and swamp) in Brazil were used. The technique using sodium metaphosphate was successful because the structure of the fossil pollen grains and spores showed no retention of extraneous organic matter, thus facilitating their morphological identifications. The pollen grain...

... resulting in a squeezing failure of the underlying soil and significant damage to the embankment. Bearing failures in cyclically softened organic soils produce damage similar to that typically associated with lateral spreading. Figure 6 demonstrates such a failure in a peat bog underlying Vine Road...

... in a single event. Blanket peat formed on the debris cone surface at 3820–3496 cal years BP. Sediment slurries are recorded across the peat after this time, at c . 3950– c . 3100, c . 2000 and c . 1400 cal years BP, and at c . 1200– c . 1100 cal years BP. They were much less significant events. They can...

... of laminated sediments from a lake which had begun to accumulate earlier. Radiocarbon dating of peat overlying the lake sediments gave 10 176–10 315 cal years BP, but morphological and stratigraphical evidence indicates that drainage of the lake occurred earlier and only shortly before movement of the scree...

...Juan Pedro Rodríguez-López; Ana R. Soria; Carlos L. Liesa ABSTRACT Coal clasts associated with extreme floods are prone to survive and maintain their large size, contrary to the general belief that distance from the parent peat layer reduces the size of transported clasts. Contrary to apparent...

... by ruling out >0.5 m of coseismic coastal subsidence for the past 2000 yr. Although the stratigraphy in cores and outcrops includes as many as 12 peat-mud contacts, like those commonly inferred to record subsidence during megathrust earthquakes, mapping, qualitative diatom analysis, foraminiferal...
