We would also like to point out that the complete removal of potential early‐ to mid‐Weichselian till deposits at KKH would require an erosional force that is typically associated with an ice advance or exceptionally high‐energy fluvial/littoral processes, capable of transporting away glacial debris including metre‐sized boulders.…”

Here we present a multi-proxy investigation of the Klein Kl€ utz H€ oved (KKH) coastal cliff section in northeastern Germany, involving lithofacies analysis, micromorphology, micropalaeontology, palynology and luminescence dating of quartz and feldspar. We subdivide the local stratigraphy into three depositional phases. (i) Following a Saalian advance (MIS 6) of the Scandinavian Ice Sheet, the penultimate deglaciation (Termination II) at the site occurred between c. 139 and 134 ka, leading to the establishment of abraided river system and lacustrine basins under arctic-subarctic climate conditions. (ii) In the initial phase of the Eemian interglacial lacustrine deposits were formed, containing warm-water ostracods and a pollen spectrum indicating gradual expansion of woodlands eventually containing thermophile deciduous forest elements. A correlation of the local pollen assemblages with Eemian reference records from central Europe suggests that fewer than 750 years of the last interglacial period are preserved at KKH. The occurrence of brackish ostracods dates the onset of the Eemian marine transgression at the section at c. 300-750 years after the beginning of the last interglacial period. (iii) Directly above the Eemian record a~10-mthick sedimentary succession of MIS 2 age was deposited, implying a significant hiatus of c. 90 ka encompassing the time from middle and upper MIS 5e to late MIS 3. During the Late Weichselian, KKH featured a depositional shift from (glacio-)lacustrine to subglacial to recessional terminoglacial facies, with the first documented Weichselian ice advance post-dating 20AE2 ka. Overall, the KKH section represents an exceptional sedimentary archive for palaeoenvironmental reconstructions, covering the period from the Saalian glaciation and subsequent Termination II to the early Eemian and Late Weichselian. The results refine the existing palaeogeographical and geochronological models of the late Quaternary history in the southwestern Baltic Sea area and allow correlations with other reference records in a wider area.

“…The glacial deposits exposed at the Jasmund study area have been subdivided into at least three tills (M1–M3) with intercalated units (I1 and I2) comprising gravel, sand and clay. The regional stratigraphic correlation of the individual tills and their relationships to the interbedded sediments is still under debate (see Kenzler et al ., , and references therein). The oldest M1 till is widely thought to have been deposited during the Saalian (Wolstonian) glaciation [Marine Isotope Stage (MIS) 6] (Panzig, ; Müller and Obst, ) and is interpreted as a subglacial traction till (Evans et al ., ).…”

The Wissower Bach Syncline on the Jasmund Peninsula (NE Germany) has been examined to understand the complicated glacitectonic environment in the southern Baltic Sea region, comprising folds and thrust faults from the Weichselian Pleniglacial. Soft-sediment thin sections from a SW-dipping thrust fault at the southwestern limb of the syncline between Cretaceous chalk (hangingwall) and Pleistocene deposits (footwall) were analysed using micromorphology and microstructural mapping. Within the diamicton bounding the fault, three different clast microfabrics were distinguished: an older, but dominant S1 fabric; a second S2 foliation orientated perpendicular to S1; and a younger subvertical S3 fabric. These fabrics developed during large-scale folding and thrusting, subsequent fabric rotation adjacent to the thrust fault accompanied by dewatering of the diamicton and extension; the latter implying late-stage reactivation and gravitational relaxation at the southwestern limb of the syncline as the ice retreated. The combination of a 3D microstructural model and the macroscale information has led to the development of a detailed model for the evolution of the Wissower Bach Syncline during glacitectonism and the localised reactivation of the associated thrusts in response to ice retreat. Moreover, this methodology provides a robust dataset on which to interpret the structural evolution of glacitectonic complexes.

In the course of field work based on geo log i cal and land slide map ping and spa tial anal y ses of map in for ma tion at least 2 types of land slides were iden ti fied. Type I: sim ple land slides de vel oped in ho mo ge neous and un dis turbed rocks, for in stance -loams, clays and sands. This type of land slide in cludes many ex am ples de vel oped mainly on the stretch (seg ment of the stud ied area) ap prox i mately be tween 132.25 and 133.50 km and 128.50 and 129.50 km of the Pol ish coast line. Type II: complex land slides in which the move ment and dis place ment of rock masses oc curs un der com plex geo log i cal and hydrogeological con di tions. The com plex fac tors are de ter mined by phe nom ena such as glaciotectonics, dis con ti nu ities of rock lay ers and thrust zones; the slip sur face oc curs at con sid er able depths, and some times sev eral slip sur faces can be distin guished. These land slide types are lo cated in the vi cin ity of Jastrzêbia Góra and Rozewie, near km 134 and 131.5. Pre diction of the for ma tion of this land slide types is dif fi cult. Even if long-term ob ser va tions are avail able, the mass move ment, vari able over time, is dif fi cult to in ter pret. It is clear that the changes are con tin u ous, but oc cur with vary ing in ten sity. Proper rec og ni tion of the types of mass move ment is cru cial to es tab lish ing the ap pro pri ate meth ods to pre vent their de vel op ment.
