Variations in magma composition in time and space along the Central Andes (13°S-28°S)
(2006-11-01)Meso-Cenozoic magmatic arc systems of the Central Andes (CA) result from the subduction of the Nazca Plate beneath the South America plate since Jurassic time, the arc progressively shifted ... -
Verbundene Mikroporosität in Kristallingesteinen
(2001-06-13)The necessity of depositing radioactive wastes and other toxic substances sealed off from the biosphere, led to the idea of the creation of underground disposal sites in suitable geological ... -
Violence and volume: an experimental study of CO2 driven eruptions of Colli Albani
(2022-04-07)This thesis presents the first rheological investigations of melts from the Colli Albani Volcanic District (CAVD) near Rome (Italy). Despite their silica-poor (< 45 wt%) and ultrapotassic composition – indicating a low ... -
Volatilitätskontrollierte Fraktionierung refraktär-lithophiler Elemente in Meteoriten und der Erde
(2014-08-14)During the condensation of the elements in the early solar system, volatility-controlled fractionations occurred. Such fractionations of refractory lithophile elements in individual chondrite components and between bulk ... -
Volcanic Rocks from Central Italy: An Oxygen Isotopic Microanalytical and Geochemical Study
(2001-02-22)The aim of this work is an investigation on the origin of the Tertiary and Quarternary volcanic rocks in central Italy. The volcanism in this region is characterised by potassic to ultrapotassic ... -

(2003-11-28)Due to their number of ecological functions and endemic flora and fauna, the tropical montane cloud forests of Guatemala need to be protected. They were classified by the World Bank as ... -
Water level response to harmonic disturbances in confined aquifers: modeling, global sensitivity, and applications
(2024-06-13)In well-aquifer system, oscillatory water levels are often observed in monitoring wells when the aquifer is perturbed by harmonic disturbances, such as oscillatory pumping, ocean tide and seismic waves. In general, the ... -
Water management strategies towards sustainable agricultural development, taking Managed Aquifer Recharge (MAR) and brackish water utilization into Account: Case Study: Auja, LJV, Palestine.
(2019-06-07)Increasing water irrigation demand combined with water scarcity and deterioration of the water quality in the Lower Jordan Valley (hereafter referred to as LJV) - Palestine, has led to a serious challenge in managing ... -
