Climatic Fluctuations in the Early and Middle Copper Age - First Isotope Investigations at the Water Supply of Los Millares in SE SpainAnorte Elisabeth Jakowski , Andrea Schröder-Ritzrau & José Miguel Alonso Blanco
The Copper Age fortification of Los Millares is located 15 km north of Almería in Andalusia. At least between 3,541 BC (+/- 92 years) and 2,591 BC (+/- 22 years) there existed a water conduit, the so-called "aqueduct of Los Millares", with which water was conveyed to the settlement from a spring located about 1.25 km outside. U and Sr isotope analyses of groundwater samples in the catchment area as well as of the calcareous...
OneGeochemistry: Enabling a coordinated online global network of multiple distributed geochemical repositories and databasesKerstin Annette Lehnert , Lesley Wyborn , Dominik Hezel , Alexander Prent , Kirsten Elger , Geertje ter Maat , Marthe Klöcking & Jens Klump
Since the discipline of ‘geochemistry’ was first defined in 1838, geochemical data has been pervasively acquired and used in the Earth, environmental and planetary sciences and become fundamental for understanding past, present, and future processes in natural systems. Initially, geochemical data was published in hard-copy literature, but as analytical systems became computerised, major digital databases emerged (EarthChem, PetDB, OZCHEM and GEOROC) which revolutionised data access. They have proven the power of re-use of geochemical data...
Pre-Variscan (Lower Devonian) deformation of the Silurian magmatic arc of the East Odenwald (Mid-German Crystalline Zone, Variscides)Henri Paul Meinaß , Wolfgang Dörr & Eckardt Stein
The Böllstein Odenwald is forming a large anticline of mainly pre-Devonian rock in the Mid-German Crystalline Zone (MCGZ). The contact between core and schist envelope of the anticline is well exposed at Weichberg quarry. Metasedimentary rocks of the schist envelope are intruded by granodioritic sills of a Silurian magmatic arc, showing at least two folding phases: Recumbent tight isoclinal folds are overprinted by upright gentle folds. A pegmatite dike, intruding at 411 ±2 Ma (U-Pb...
Was brauchen Kinder und Jugendliche zum guten Leben? Was ist ihnen wichtig? Zu welchen Themen wollen sie gefragt und gehört werden? Und wie könnten solche Befragungen aussehen? Das haben Jugendliche unseres JugendExpert:innenTeams mit anderen Jugendlichen in Peer2Peer-Workshops diskutiert. Denn junge Menschen wollen gefragt und gehört werden und in Belangen, die sie betreffen, mitentscheiden. Das findet aber vielfach nicht statt. Die Publikation bietet einen ersten Einblick in die Herangehensweise sowie die wissenschaftlichen Auswertungen der ersten Online-Workshops...
Half-precession signals in Lake Ohrid and their spatial and temporal connection to proxy records in the European realmSArne Ulfers , Christian Zeeden , Silke Voigt & Wonik Thomas
Lake Ohrid (North Macedonia/Albania) is Europe’s oldest lake and thus is a valuable archive for changes of local (hydro)climate during the last 1.36 million years (e.g., Wagner et al. 2019). During an International Continental Scientific Drilling Program campaign in 2013, geophysical downhole logging by the Leibniz Institute for Applied Geophysics acquired continuous datasets of physical properties. Additionally, sediment cores from four sites were obtained, the deepest with a length of 570 m (Wagner et al....
Rock alteration at the post-Variscan nonconformity: implications for Permo-Carboniferous surface weathering versus burial diagenesisFei Liang , Adrian Linsel , Matthias Hinderer , Jens Hornung , Dirk Scheuvens & Rainer Petschick
Nonconformity surfaces are key features to understand the relations among climate, lithosphere and tectonic movements in Earth history. One of the most prominent stratigraphic surfaces in Central European is the post-Variscan nonconformity separating the metamorphic Variscan basement from non-metamorphic platform deposits starting in the Upper Carboniferous, but more widely distributed since the Permian. This study aimed to analyze and distinguish the physical and chemical processes happening during exposure of the surface as well as during...
Here, we present element to Ca ratios (Mg/Ca, Sr/Ca, Na/Ca and Mn/Ca) and stable isotope data (δ18O, δ13C) of the parasitic foraminifer Hyrrokkin sarcophaga, collected from two different host organisms, Desmophyllum pertusum - a cold-water coral commonly found in cold-water coral reefs and Acesta excavata - a bivalve associated with cold-water coral reefs. Our results reveal that the geochemical signature in H. sarcophaga is influenced by the host organism. Sr/Ca ratios are 1.1 mmol mol-1...
Due to recent developments in socio-cultural as well as technological terms, music is increasingly being revealed as a phenomenon of digital spaces and information technology. During the pandemic, when musical life took place almost exclusively online, a tremendous reinforcement and acceleration of this process was experienced.
