“…The basement rock of the Hupo basin primarily consists of Precambrian gneiss and Jurassic granite, overlaid by Quaternary and Pliocene sediment (Hong et al, 2022 ). In particular, the sediment covering the uppermost layer (up to ~ 6 m) primarily consists of sandy mud/mud that was intensively deposited during the Late Pleistocene and Holocene; notably, such deposits are most abundantly distributed within Hupo Trough (Fig.…”

“…In particular, the sediment covering the uppermost layer (up to ~ 6 m) primarily consists of sandy mud/mud that was intensively deposited during the Late Pleistocene and Holocene; notably, such deposits are most abundantly distributed within Hupo Trough (Fig. 2 a and b) (Hong et al, 2022 ; Jun et al, 2014 ). The surface sediment in the study area was considered to originate primarily from the transport by ocean currents, particularly the East Korean Warm Current (EKWC) and North Korean Cold Current (NKCC; Fig.…”

“…First, it is geologically isolated from various anthropogenic sources of contamination. Second, the seafloor surface sediments in the Hupo basin have previously been extensively investigated through depositional and geochemical analyses, providing valuable background information for assessing their potential application as peloids (Hong et al, 2022 ; Khim et al, 2021 ; Kim et al, 2010 ; Lee et al, 2015 ; Son et al, 2022 ). Third, box/piston core analyses have confirmed that these sediments have a consistent composition across a wide area.…”

The present study firstly reports surface sediment from the subsea depth of 200 m as a potential natural peloid. The fine-silt sediment exhibited a consistent clay mineral composition dominated by illite, chlorite, kaolinite, and diatomite. The most abundant clay mineral was illite/mica, with other minerals loosely packed in a face-to-face orientation. The thermal conductivity, specific heat capacity, and cation-exchange capacity of the sediment were in the range 0.855–0.885 W/m K, 2.718–2.821 J/g °C, and 23.06–32.96 cmol/kg, respectively. The concentrations of most toxic elements in the sediment were considerably lower than the limits set by domestic cosmetic regulations and other international standards. The analyzed samples exhibited similar properties to those of previously reported peloids, thus making them suitable for use in the field of pelotherapy; furthermore, the consistency in data across a wide peloid-distribution area is expected to enable economically viable mining. Future investigations should aim to to evaluate the long-term effects on the skin, the bioavailability of potentially hazardous substances, and the therapeutic efficacy for various skin conditions.

“…However, currently this term is increasingly used to describe currents that develop along all types of smaller and/or larger (regional) slopes and morphological barriers, for instance in shelf environments (e.g., Verdicchio and Trincardi 2008;Hübscher et al 2019;Hong et al 2022).…”

Upper Cretaceous contourites from northwestern Poland in the vicinity of the Szamotuły salt diapir

This paper presents the results of seismostratigraphic interpretation of the Upper Cretaceous sedimentary succession preserved within two synclines flanking the Szamotuły diapir in northwestern Poland. This succession is characterized by a complex Santonian–Campanian internal geometry characteristic of contourites – that is, deposits formed by contour (bottom) currents. The aim of the present paper is to document these contourites using 2D seismic reflection profiles calibrated by the Obrzycko 1 well. The contourite drifts in the immediate vicinity of the Szamotuły structure exhibit elongated mounded shapes, with adjacent concave moats. At greater distances from the diapir, gradual aggradational patterns are observed. The formation of these Santonian– Campanian contourites was associated with growth of the Szamotuły diapir during regional compression and Polish Basin inversion. These contour currents and associated contourites formed an integral part of a regional axial depositional system developed within the flanks of the Mid-Polish Anticlinorium. Furthermore, this paper discusses the potential role of contourites as palaeomorphological indicators of palaeoslopes in varied geodynamics settings, such as inverting sedimentary basins, as opposed to the passive margins upon which they have been most commonly documented.
