Loess–palaeosol sequences (LPSs) represent continental and non-aquatic archives providing detailed information on Quaternary environmental and climate changes. We present an integrative approach combining sedimentological, rock magnetic, and bulk geochemical data, as well as information on Sr and Nd isotope composition. The approach adds to a comprehensive understanding of LPS formation including changes in dust composition and associated circulation patterns during Quaternary climate changes.

We reconstructed a wetland environment for a late Middle to Upper Pleniglacial (approx. 30–20 ka) loess sequence in western Germany. Typically, these sequences reveal terrestrial conditions with soil formation processes during this time frame. The here-investigated section, however, was influenced by periodical flooding, leading to marshy conditions and a stressed ecosystem. Our results show that the landscape of the study area was much more fragmented during this time than previously thought.

Short summary
Glacial trimlines are visible breaks in vegetation or landforms that mark the former extent of glaciers. They are often observed as faint lines running across valley sides and are useful for mapping the three-dimensional shape of former glaciers or for assessing by how much present-day glaciers have thinned and retreated. Here we present the first application of a new trimline classification scheme to a case study location in central western Spitsbergen, Svalbard.

Short summary
The Miaoli Tableland (northwestern Taiwan) consists of a sequence of fine-grained tidal to coarse fluvial late Quaternary sediments which underwent a spatially differentiated uplift and fluvial dissection. They reveal repeated rework processes of fluvial cobbles from the highlands to the coast. A new landform classification based on high-resolution 3D terrain analysis results in a new interpretation of the landform evolution. The results favour a local rarely used Quaternary stratigraphic code.

Short summary
A main element in Büdel's concept is his quite provocative link between climate zones and geomorphological processes, a strong relation which was frequently contested later. Büdel's contribution is still relevant in modern times as the present-day climatic change will probably also invoke a poleward shift of climatic zones, accompanied by associated shifts in geomorphological environments and ecosystems.

Our new concept of the Weichselian ice dynamics in the south-western sector of the Baltic Sea depression is based on existing geochronological data from Germany, Denmark and southernmost Sweden, as well as new data from north-east Germany. Previous models are mainly based on the reconstruction of morphologically continuous ice-marginal positions, whereas our model shows a strong lobate and variable character of ice advances. We strongly suggest an age- and process-based approach in the future.

The Black Forest was covered by a 1000 km2 large ice cap during the last glaciation. Glacial landforms in the area north-west of the highest summit of the Black Forest, the Feldberg (1493 m above sea level), were investigated to select suitable sampling sites for dating glacial landforms in future studies. Some of the terminal moraines described in this study are mapped for the first time. The application of dating methods will provide insights into the chronology of the last glaciation.

Geomorphological mapping and analysis conducted as an initial step towards a future sediment budget study of the middle Waimakariri River (Southern Alps, New Zealand) reveals that the traditional concept of the temporary palaeolake
glacial Lake Speightis conflicting with our conclusions of realistic chronosequences and timescales of para- and postglacial landform development. Especially the temporal and causal relation to the last deglaciation needs to be questioned and will be discussed.

Short summary
We present 10Be-based erosion rates for the Harz Mountains. Erosion is slope-dependent, and the Harz topography evolves at rates of a few tens of meters per million years. The 300 m difference in elevation between a planation surface in the Harz and its lower surroundings results from rock uplift, erosion of sediments in adjacent areas, and migration and dissolution of Permian salt. Active reverse faulting along the northern Harz is inconsistent with geological, geophysical, and geodetic data.
