Calcretes aus jungpaläozoischen Bodenbildungen - ein möglicher Proxy für die CO<sub>2</sub>-Konzentration der Paläoatmosphäre
(2003-04-03)The use of pedogenic carbonates (calcretes) in estimating CO2 concentrations in the Late Paleozoic atmosphere has been examined. For this purpose Cerling (1991,1999) submitted a theory based ... -
Carbon Dioxide un ultrapotassic silicate melts: Experimental insights on solubility and decompression induced vesicle nucleation
(2021-10-01)Until today, the explosivity of volcanic eruptions cannot be forecasted by even the most modern monitoring techniques. The processes causing these events, endangering the lives of millions of people, happen deep inside the ... -
Carbonate factories in the early Archean and their geobiological impacts
(2023-08-08)Paleoarchean carbonates in the Pilbara Craton (Western Australia) are important archives for early life and environment on early Earth. Amongst others, carbonates occur in interstitial spaces of ca. 3.5–3.4 Ga pillow basalts ... -
Cathodoluminescence and characterisation of defect structures in quartz with applications to the study of granitic rocks
(2001-03-06)The presented study contributes in solving the causes of cathodoluminescence (CL) of quartz. For this purpose a variety of quartzes from different geological environments has been systematically ... -
Cenozoic tectonic deformation, thermochronology and exhumation of the Diancang Shan metamorphic massif along Ailao Shan-Red River shear zone, southeastern Tibet, China
(2011-06-16)Chapter 1 this thesis outlines the Cenozoic tectonic evolution of a critically important area within the India-Eurasian collision zone, i.e. the Diancang Shan (DCS) metamorphic massif along ... -
Challenges and perspectives of the North Frisian Halligen Hooge, Langeness and Nordstrandischmoor
(2015-03-03)Low coastlands, marshlands and islands all over the world are challenged by rising water levels due to climatic changes. Especially tidal marshlands can compensate for a certain degree of hydrological changes. Their rate ... -
Changes in tropical rainforests landscapes as a consequence of selective logging and indigenous shifting cultivation in Forest Reserve Imataca (central zone) Bolívar State, Venezuela.
(2005-07-27)The degradation process of tropical land forests caused by traditional indigenous agriculture and commercial logging was evaluated in the central sector of the Forest Reserve Imataca in the ... -
Characterization of groundwater flow and vulnerability assessment of karstic aquifers - Development of a travel time based approach and application to the Tanour and Rasoun spring catchment (Ajloun, NW-Jordan)
(2016-08-24)Understanding the karst aquifer response to precipitation and contaminants transport, especially in arid to semi-arid areas, is a very important issue and a challenge due to the unique and heterogeneous characteristics of ... -
Characterization of Hydraulic Properties in Fractured Aquifers Using Slug Test-based Hydraulic Tomography and Thermal Tracer Tomography
(2022-10-25)Fractured aquifers are widely distributed on the earth’s surface and are frequently encountered in many underground projects, such as groundwater resource evaluation, contaminants remediation, and geothermal energy ... -
Charakterisierung des hydromechanischen Verhaltens der Gesteine des Mittleren Buntsandsteins im Hinblick auf eine geothermische Nutzung: Strukturgeologische Geländeaufnahmen, gesteinsmechanische Untersuchungen und numerische Modellierungen
(2009-10-21)The objective of the current study was to evaluate the fluid flow in a geothermal fractured sandstone reservoir of the German Buntsandstein.The first part of the study comprises the analysis ... -
Charakterisierung minimaler und maximaler Hemmkonzentrationen verschiedener Spurenelemente in Biogasprozessen und Entwicklung eines vereinfachten Bestimmungsverfahrens
(2020-08-24)For optimal biogas formation processes in biogas plants numerous operating parameters must be within certain limits. A sufficient supply of essential macro- and micronutrients must be guaranteed for the conversion and ... -
Chemical water quality in Selenge River Basin in Mongolia: spatial-temporal patterns and land use influence
(2018-10-18)Water is essential for life and for all human activities but also for preserving the environment and its resources. Rapidly growing population, intensification of agriculture, industrialization, urbanization, development ... -
Classification of main irrigated crop types towards sustainable development using Landsat and Sentinel data by GIS and remote sensing techniques in a semi-arid area in Tashkent Province, Uzbekistan
(2024-02-02)As the world population increases and cropland expansion occurs, there will be a high need in the food supply soon which will require higher agricultural yields. Crop yield estimation, management, and production assessments ... -
Composition and compositional zoning of olivine as a tracer for pre-eruptive magmatic processes: Application to Piton de la Fournaise, Laacher See, and Shiveluch volcano
(2020-08-12)This dissertation deals with the reconstruction of pre-eruptive magmatic processes with respect to their timescales. Deep recharges of mafic magma into shallower reservoirs and subsequent magma mixing are assumed to play ... -
