Druck- und Temperaturentwicklung der metamorphen Deckeneinheiten des Escambray Massives, Kuba
(Univ. Bochum, 2000)
Im Rahmen dieser Arbeit wurden hochdruckmetamorphe Gesteinseinheiten der Sancti Spiritus Kuppel, Escambray Massiv, Zentralkuba, petrologisch und geochemisch untersucht. Die Analysen bestätigen eine Unterteilung der Gesteine ...
Metall-Silikat-Verteilungsverhalten von Nickel und Kobalt in Abhängigkeit von Druck und Temperatur: Implikationen für planetare Differentiationsprozesse
(Univ. Köln, 2005)
Die Erde, der Mond und die anderen terrestrischen Planeten haben einen eisen-nickelreichen, metallischen Kern, der sich in der Frühphase der Geschichte dieser Planeten von der Silikat-phase, die heute den Mantel bildet, ...
Exhumation of ultrahigh-pressure metamorphic oceanic crust from Lago di Cignana, Piemontese zone, Western Alps
(Univ. Bochum, 1998)
Die Exhumierungsgeschichte der ultrahochdruckmetamorphen (UHPM) Gesteine am Lago di Cignana wurde rekonstruiert. Die Eklogite wurden unter UHPM Bedingungen (ca. 600 ʿC, 2,7 GPa) verformt. Bei Temperaturen (T) um 500 ʿC und ...
Analyse von Butylzinnverbindungen in Sedimenten mittels GC-AED
(Univ. Hamburg, 2007)
Organotin compounds are variously used industrial chemicals. One of the most toxicological relevant compounds is tributyltin (TBT). TBT has been used as an effective component in antifouling paints for decades. Thus, it ...
Laser ablation ICP-MS in paleoceanography
(Univ. Bremen, 2008)
The different benthic foraminiferal species (epibenthic as well as endobenthic) colonize wide areas of the ocean floor and are widely used for paleoceanographic reconstructions. To improve these reconstructions, it is an ...
The effect of acidic polysaccharides on the biogeochemistry of iron in the marine environment
(Univ. Bremen, 2008)
In the early 1990`s the first IPCC report stated the effect of anthropogenic CO2 emissions on global warming and John Martin`s Iron Hypothesis (Martin and J.H 1990), relating atmospheric dust deposition, a major source of ...
High field strength element systematics and Lu-Hf & Sm-Nd garnet geochronology of orogenic eclogites
(Univ. Frankfurt (Main), 2008)
Concerning the Bulk Silicate Earth (BSE), the depleted mantle and the continental crust are thought to balance the budget of refractory and lithophile elements, resulting in complementary trace element patterns. However, ...
Methane oxidation and carbon assimilation in marine sediments
(Univ. Bremen, 2008)
Anaerobe Oxidation of Methane, AOM, methanotrophy, stable isotope labeling, stable isotope probing, carbon assimilation, flow-through columns, ANME, Seep-SRB, Gullfaks, Tommeliten. - Anaerobic oxidation of methane (AOM) ...
Predictive modeling of organic pollutant leaching and transport behavior at the lysimeter and field scales
(Univ. Dresden, 2007)
Soil and groundwater pollution has become a global issue since the advent of industrialization and mechanized agriculture. Some contaminants such as PAHs may persist in the subsurface for decades and centuries. In a bid ...
