Fore-arc mantle alteration, fluid activity and fluid-rock interaction revealed from Serpentinite Mud Seamounts at the Mariana Convergent Margin System (IODP Expedition 366)
Autor: Walter Kurz, Irena Miladinova, Kurt Krenn, Thomas Hilmbauer-Hofmacher
The Mariana convergent margin provides the environment where a natural process brings materials from great depths directly to the surface. The Mariana forearc contains the only current active serpentine mud volcanism in a convergent margin setting. H

Occurrence and origin of glauconite in the Cambro-Ordovician Bliss Formation of southern New Mexico and West Texas (U.S.A.)
Autor: Karl Krainer, Peter Tropper, Kurt Krenn, Spencer G. Lucas
Publikováno v: Journal of Sedimentary Research. 92:353-370
In southern New Mexico and West Texas, USA, the Late Cambrian–Early Ordovician Bliss Formation is a relatively thin and dominantly siliciclastic succession that was deposited on the Proterozoic basement during a major global transgression. The Blis

Anatectic Granitic Pegmatites from the Eastern Alps: A Case of Variable Rare Metal Enrichment During High-Grade Regional Metamorphism. III: Fluid Inclusions as Potential Indicators for Anatectic Pegmatite Parent Melt Formation
Autor: Kurt Krenn, Jürgen Konzett, Roland Stalder
Publikováno v: The Canadian Mineralogist. 60:155-169
Fluid inclusions trapped in quartz, beryl, and cassiterite from a granitic pegmatite of the Austroalpine basement of the Eastern Alps in Northern Italy were analyzed using a cooling/heating stage and micro-Raman spectroscopy with the following aims:

Publikováno v: Minerals; Volume 12; Issue 7; Pages: 873
Minerals
Fluid and solid inclusions in magmatic garnet from Permian pegmatites of the Koralpe Mountains were investigated. On the basis of MnO/(MnO + FeO) ratios, different degrees of melt fractionation during garnet growth were linked with fluid inclusion de

Neogene Metasomatism in the Subcontinental Lithosphere beneath SE Asia—Evidence from Modal and Cryptic Phosphorus Enrichment in Peridotites and Pyroxenites from Southern Laos
Autor: Nguyen Ngoc Khoi, Katharina Gröbner, Jürgen Konzett, Roland Stalder, Nguyen Van Hoang, Anna-Katharina Sieberer, Kurt Krenn, Christoph Hauzenberger, Bastian Joachim-Mrosko
Publikováno v: Journal of Petrology. 60:2413-2448
Metasomatism is the prime process to create compositional heterogeneity of the upper mantle. Mineralogical and mineral chemical changes of the mantle triggered by metasomatism can be used to deduce the nature of the metasomatic agent(s) and to constr

Beyond ultra-high pressure metamorphism: evidence for extremely high pressure conditions during frictional fusion in gigantic landslides using micro-Raman spectroscopy of quartz: the Tsergo Ri (Langtang Himal, Nepal) rockslide
Autor: Kurt Krenn, Diethard Sanders, Peter Tropper
The Tsergo Ri rockslide represents one of the world's biggest rockslides in crystalline rocks (original volume: 1010 m3). The mass movement comprises migmatites, leucogranites, orthogneisses and paragneisses (Weidinger et al. 2014). During mass-wasti

Serpentinite mud volcanism and exhumation of fore arc- and lower plate material in the Mariana convergent margin system (IODP Expedition 366)
Autor: Walter Kurz, Irena Miladinova, Arianna V. Del Gaudio, Werner Piller, Kurt Krenn
Serpentine seamounts located in the forearc region of a subduction zone setting represent an excellent natural laboratory for studying the geochemical processes acting along convergent plate margins and the associated natural hazards as well as the f
