Journal Article
Halama, R., Bebout, G., Marschall, H., & John, T. (2016). Fluid-induced breakdown of white mica controls nitrogen transfer during fluid-rock interaction in subduction zones. International Geology Review, 702-720. https://doi.org/10.1080/00206814.2016.1233834

In order to determine the effects of fluid–rock interaction on nitrogen elemental and isotopic systematics in high-pressure metamorphic rocks, we investigated three different profiles representing three distinct scenarios of metasomatic overprinting....

Slab mantle dehydrates beneath Kamchatka – yet recycles water into the deep mantle (2016)
Journal Article
Konrad-Schmolke, M., Halama, R., & Manea, V. (2016). Slab mantle dehydrates beneath Kamchatka – yet recycles water into the deep mantle. Geochemistry, Geophysics, Geosystems, 2987-3007. https://doi.org/10.1002/2016GC006335

The subduction of hydrated slab mantle is the most important and yet weakly constrained factor in the quantification of the Earth's deep geologic water cycle. The most critical unknowns are the initial hydration state and the dehydration behavior of... Read More about Slab mantle dehydrates beneath Kamchatka – yet recycles water into the deep mantle.

Magnesium isotope fractionation during carbonatite magmatism at Oldoinyo Lengai, Tanzania (2016)
Journal Article
Li, W., Teng, F., Halama, R., Keller, J., & Klaudius, J. (2016). Magnesium isotope fractionation during carbonatite magmatism at Oldoinyo Lengai, Tanzania. Earth and Planetary Science Letters, 26 -33. https://doi.org/10.1016/j.epsl.2016.03.034

To investigate the behaviour of Mg isotopes during carbonatite magmatism, we analyzed Mg isotopic compositions of natrocarbonatites and peralkaline silicate rocks from Oldoinyo Lengai, Tanzania. The olivine melilitites from the vicinity of Oldoinyo L... Read More about Magnesium isotope fractionation during carbonatite magmatism at Oldoinyo Lengai, Tanzania.
