Konsequenzen des natürlich geschlossenen Systems der Geologie (II) - Über Proportionalität in der Geologie
(2020)Die Relativierung des mathematischen Begriffs der direkten Proportionalität führt in der Geologie zur Darstellung der geometrischen und der arithmetischen Relation und zur Begründung des geologischen Binärsystems. Die ... -

(Universitätsverlag Göttingen, Göttingen, 2019)Das breite inhaltliche Spektrum der vorgestellten Region auf dem Kraton Baltica (Präkambrisches Grundgebirge, Deckgebirge, Deformationszonen, Quartärgeologie) eignet sich sehr gut für eine allgemeingeologische Exkursion ... -
Das natürlich geschlossene System - Grundlage einer theoretischen Geologie? - Eine Darstellung der inneren Logik des NGS
(2019)Es werden grundsätzliche Fragestellungen einer mathematisch bzw. axiomatisch begründeten Geologie dargestellt. -
Das natürlich geschlossene System - Grundlage einer theoretischen Geologie? - Über geologische Reflexionen von Friedrich Engels im Anti - Dühring
(2019)Das duale System proportionaler Zusammenhäng des natürlich geschlossenen Systems ( geologisches Binärsystem) ist mit der philosophisch begründeten Logik ( materialistische Dialektik) in perfekter Übereinstimmung. Somit ... -
The Suitability of Pozzolan as Admixing Aggregate for Fe0-Based Filters
(Water, 2018)Continuous gravity-fed column experiments using the methylene blue (MB) discoloration method were performed to characterize the suitability of a pozzolan (PZ) specimen as alternative admixing aggregate for metallic iron ... -
Climate effects on vegetation vitality at the treeline of boreal forests of Mongolia
(Biogeosciences, 2018)In northern Mongolia, at the southern boundary of the Siberian boreal forest belt, the distribution of steppe and forest is generally linked to climate and topography, making this region highly sensitive to climate change ... -
Snowmobile impacts on snowpack physical and mechanical properties
(The Cryosphere, 2018)Snowmobile use is a popular form of winter recreation in Colorado, particularly on public lands. To examine the effects of differing levels of use on snowpack properties, experiments were performed at two different ... -
Ideas and perspectives: hydrothermally driven redistribution and sequestration of early Archaean biomass – the “hydrothermal pump hypothesis”
(Biogeosciences, 2018)Archaean hydrothermal chert veins commonly contain abundant organic carbon of uncertain origin (abiotic vs. biotic). In this study, we analysed kerogen contained in a hydrothermal chert vein from the ca. 3.5 Ga ... -
Land Surface Temperature Variation Due to Changes in Elevation in Northwest Vietnam
(Climate, 2018)Land surface temperature (LST) is one of the most important variables for applications relating to the physics of land surface processes. LST rapidly changes in both space and time, and knowledge of LST and its spatiotemporal ... -
A fossil species of the enigmatic early polypod fern genus Cystodium (Cystodiaceae) in Cretaceous amber from Myanmar.
(Scientific reports, 2017-11-06)The monospecific fern genus Cystodium (Cystodiaceae; Polypodiales) occurs exclusively in the tropical forests of the Malay Archipelago, the Admiralty Islands, the Louisiade Archipelago, and the Solomon Islands. Divergence ... -
Fast methane diffusion at the interface of two clathrate structures.
(Nature communications, 2017-10-20)Methane hydrates naturally form on Earth and in the interiors of some icy bodies of the Universe, and are also expected to play a paramount role in future energy and environmental technologies. Here we report experimental ... -
Tracing the oxygen isotope composition of the upper Earth's atmosphere using cosmic spherules
; Höweling, Andres; Hezel, Dominik C.; Stefanak, Maren T.; Beck, Anne-Katrin; Peters, Stefan T. M.; Sengupta, Sukanya; Herwartz, Daniel; Folco, Luigi (Nature communications, 2017-06-01)
Molten I-type cosmic spherules formed by heating, oxidation and melting of extraterrestrial Fe,Ni metal alloys. The entire oxygen in these spherules sources from the atmosphere. Therefore, I-type cosmic spherules are ... -
Exhumation history and landscape evolution of the Sierra de San Luis (Sierras Pampeanas, Argentina) - new insights from low - temperature thermochronological data
(Andean Geology, 2017)This paper presents low-temperature thermochronological data and K‑Ar fault gouge ages from the Sierra de San Luis in the Eastern Sierras Pampeanas in order to constrain its low-temperature thermal evolution and ... -
Seismic-stratigraphic architecture of the Oligocene-Pliocene Camaná Formation, southern Peruvian forearc (Province of Arequipa)
(Andean Geology, 2017)Arquitectura sísmica-estratigráfica de la Formación Camaná del Oligoceno-Plioceno, Antearco del sur de Perú (Provincia de Arequipa). La Cuenca Camaná-Mollendo es una depresión de margen activo en el sur de Perú, la cual ... -

Problems related to the taxonomic placement of incompletely preserved amber fossils: transfer of the Paleogene liverwort Cylindrocolea dimorpha (Cephaloziellaceae) to the extant Odontoschisma sect. Iwatsukia (Cephaloziaceae)
(Fossil Record, 2017)A revision of the Baltic and Bitterfeld amber fossils assigned to Cylindrocolea dimorpha (Cephaloziellaceae) has yielded evidence of the presence of multicellular, bifid underleaves, which have not previously been reported ... -
Rhizosphere hydrophobicity: A positive trait in the competition for water.
(PloS one, 2017)The ability to acquire water from the soil is a major driver in interspecific plant competition and it depends on several root functional traits. One of these traits is the excretion of gel-like compounds (mucilage) that ... -
Relict high-Andean ecosystems challenge our concepts of naturalness and human impact
(Scientific Reports, 2017)What would current ecosystems be like without the impact of mankind? This question, which is critical for ecosystem management, has long remained unanswered due to a lack of present-day data from truly undisturbed ecosystems. ...
