The rank of climatic oscillations during MIS 11c (OHO and YHO) and post-interglacial cooling during MIS 11b and MIS 11a in eastern Poland

Geological Quarterly (2019)

Anna Hrynowiecka Marcin Żarski Wojciech Drzewicki

Lacustrine sediments representing Marine Isotope Stage 11 (MIS 11) were found in Hermanów (SE Poland) in a present-day closed depression under a thin cover of Weichselian and Holocene deposits (1.4 m). These sediments filled a palaeolake created as a result of melting of a dead-ice block at the end of MIS 12. Geological research has excluded the presence of an ice sheet during MIS 12 in this area. The lobe of the ice sheet of this glaciation was located several kilometres to the west of Hermanów. The palaeolake was part of a larger palaeolakeland in southeastern Poland, formed during MIS 11. The palaeomorphology of this interglacial is evident in the contemporary relief of the area and the outline of the lakes corresponds to the pattern of the closed palaeodepressions. Based on the record of sediments from Hermanów, a new perspective regarding the sub-division of MIS 11 is presented. Two regressive phases are observed in the Holsteinian Interglacial (MIS 11c) – OHO and YHO. The subsequent substages with five cold fluctuations according to the newest stratigraphic standards should be assigned to MIS 11b with a very clear cooling and a slightly warmer MIS 11a. Carbon isotopic composition of organic matter corroborates geological and environmental analysis. The isotopic composition suggests two cooling periods: OHO and MIS 11b. Stable climatic conditions with little temperature fluctuations persisted between the cooling periods.

Stable isotope studies of moss sulfur and sulfate from bog surface waters

GEOCHEMICAL JOURNAL (2008)

Grzegorz Skrzypek Tasuku Akagi Wojciech Drzewicki Mariusz Orion Jędrysek

Two moss genera (Sphagnum and Polytrichum) were collected seasonally in two close (∼0.45 km distance) but environmentally different locations, an Open bog and a Spruce forest at Hala Izerska (the Izerskie Mts./SW Poland), for the stable isotope analyses of plant in-body sulfur. Simultaneously, surface water was collected in places of moss growth and along the creek discharging the bog, for stable isotope analysis of sulfate sulfur (5 locations/5 times in growing seasons). The δ34S value of the analyzed mosses varies from 3.99 to 10.24‰ for Sphagnum and from 4.18 to 6.48‰ for Polytrichum. The δ34S value of aqueous sulfate in creek waters, depending on location and season, ranges from 3.72 to 20.26‰. The significant correlation between the plant in-body sulfur concentration and the isotopic composition was observed for Sphagnum as well as loose correlation between δ34S of sulfates in surface water and moss in-body sulfur. The fractionation factor, possibly caused by two processes of sulfate assimilation by Sphagnum and sulfate reduction by bacteria, calculated based on Rayleigh's distillation model equals about 4‰. The high correlation and simultaneous increase of δ34S(SO42-) and δ13C(DIC) values downstream the creek discharging the bog suggest that the lighter isotopes of carbon and sulfur (12C and 32S) are preferentially removed, probably due to assimilation by plants. The present results imply the original signature of the source of sulfur in the environment is greatly altered by the biological activities in bog water.

Preliminary results of sulphur isotope studies on sulfides from selected ore deposits and occurrences in the Karkonosze–Izera Massif (the Sudety Mts., Poland)

Mineralogia (2012)

Abstract Preliminary sulphur isotope data are presented for selected ore deposits and occurrences in the Karkonosze-Izera Massif, namely, polymetallic mineralization sites at Budniki, Ciechanowice, Izerskie Garby and Sowia Dolina, and the pyrite deposit at Wieściszowice. The data reveal two populations of δ34S values: from 2.74 to 3.95‰ (pyrrhotites and pyrites in Sowia Dolina, and some pyrites in Wieściszowice) and from 0.79 to 1.8‰ (pyrites in Budniki, Ciechanowice and Izerskie Garby, and some pyrites from Wieściszowice). All of the data are indicative of endogenic sulphur typical of hydrothermal mineralization despite the genetic differences between the sites.
