“…storm waves to develop (Figs. 1, 3c; Li et al 2014). This assertion is well-supported by geomorphic and sedimentological data from elsewhere in the paleolake plain (e.g., Krist and Schaetzl 2001;Schaetzl et al 2016) and, though we have not performed the wave theory calculations, is reasonable, given that modern November storms in southern Georgian Bay commonly produce waves >3 m high 2 and in extreme cases have produced waves in excess of 11 m ("White Hurricane" of November 1913; Brown 2002).…”

“…[Colour online. ] ties, record decreased accommodation space due to basin infilling and are interpreted to record sediment deposition in a shallow lacustrine environment between fair-weather and storm wave base (Li et al 2014). Soft sediment deformation features and horizontal erosional surfaces likely reflect dewatering caused by rapid sediment deposition and (or) storm wave shock (Molina et al 1998) and erosion by large waves during the onset of storm events (Eyles and Clark 1988).…”

Stratigraphic analysis of Late Wisconsin and Holocene glaciolacustrine deposits exposed along the Nottawasaga River, southern Ontario, Canada

Analysis of 56 outcrop exposures in cut banks along the Nottawasaga River in southern Simcoe County, Ontario, Canada, has led to the identification of eight stratigraphic units (SU1–SU8) that represent a record of changing environmental conditions during deglaciation and exhibit strong controls on shallow groundwater flow in the region. The stratigraphic succession is floored by the Late Wisconsin Newmarket Till (SU1), which is locally overlain by ice-proximal debris flow deposits (SU2). These glacial sediments are overlain by glaciolacustrine silt rhythmites (SU3) that pass upwards into deltaic sand (SU4) and channelized fluviodeltaic sand and gravel (SU5). Lying above the fluvial deposits are widespread interbedded glaciolacustrine sands and silt (SU6), which coarsen up-section toward the ground surface. The succession is locally capped by fluviodeltaic (SU7) and younger fluvial (SU8) deposits. These SUs record sedimentary environments that existed during deglaciation of the region and provide insight into the evolution of glacial lakes Schomberg and Algonquin and the Nipissing phase of the upper Great Lakes. The environmental changes described from sediments along the Nottawasaga River provide insights into basin-scale events that occurred throughout the upper Great Lakes during deglaciation. Qualitative observations of groundwater discharge from sediments at outcrop faces are used to characterize the hydraulic function of the stratigraphic units as well as possible preferential groundwater flow pathways in the shallow subsurface.

Several event layers have been identified in lacustrine deposits in the AErI Basin of Anatolia (E Türkiye). Sedimentological and palaeontological data newly indicate a storm-induced origin for some of them. The sedimentary structures in three sections, a few tens of metres apart from each other laterally, such as hummocky cross-stratification, wave-generated cross-bedding, parallel bedding, erosional surfaces, and graded bedding, which are considered characteristic of tempestites, are clearly present. Additionally, fining-upwards units and biogenic escape structures located at different levels of these sections indicate a similar origin. The vertical variations in layer thickness, grain size, and sedimentary structures in these sedimentary sections indicate fluctuating hydrodynamic conditions during deposition, while lateral decrease in the size and wavelength of the structures reflects deepening. This interpretation of storm-induced deposition is compatible with regional palaeoclimatological and palaeogeographical data, and is supported by evidence of Quaternary storm-induced sedimentation in adjacent lacustrine basins in the region

Discussion of Yang et al. (2017, Acta Geologica Sinica 91:749–750) A new discovery of the Early Cretaceous supercritical hyperpycnal flow deposits on Lingshan Island, East China

Yang et al., Acta Geologica Sinica‐English Edition, 91(2), pp. 749–750 claim that they discovered supercritical hyperpycnal flow deposits in the Early Cretaceous strata on Lingshan Island, East China. We would like to discuss this paper under the following topics: (a) the terminology of “supercritical hyperpycnal flow,” (b) hyperpycnal flow deposition, and (c) supercritical flow deposition. Our aim is twofold in that the following debate will help unravel the complexities associated with the controversy around the paleosedimentary environment and sediment dynamic processes of the early Cretaceous deposits on Lingshan Island, in addition to providing an understanding of hyperpycnal flow and supercritical flow deposits. The Beilaishi section deposits on Lingshan Island are more likely storm‐induced tempestites within the lacustrine basin delta front and associated deep lacustrine turbidites. Frequent earthquakes due to tectonic‐magmatic activity are the most likely triggers for lacustrine storms.
