Zircon micro-inclusions as an obstacle for in situ garnet U–Pb geochronology: an example from the As Sifah eclogite locality, Oman

Jesse B. Walters, Joshua M. Garber, Aratz Beranoaguirre, Leo J. Millonig et autres

Garnet is commonly used to calculate pressure ( P )–temperature ( T ) histories of metamorphic rocks, as well as to monitor changes in bulk-rock composition ( X ) and deformation ( d ). In situ U–Pb geochronology by laser ablation–inductively coupled …

Zircon micro-inclusions as an obstacle for in situ garnet U-Pb geochronology: An example from the As Sifah eclogite locality, Oman

Abstract. Garnet is commonly used to calculate pressure (P)-temperature (T) histories of metamorphic rocks, as well as to monitor changes in bulk-rock composition (X) and deformation (d). In situ U-Pb geochronology by laser ablation-inductively coupled mass spectrometry (LA-ICPMS) is a rapid and …

Iodine speciation in basaltic melts at depth

C. Sanloup, Clémence Leroy, B. Cochain, Tobias Grützner et autres

The speciation of iodine in basalts has been investigated by combining in situ X-ray diffraction at high pressures and temperatures up to 4.9 GPa and 1600 °C, and Raman spectroscopy on recovered high pressure glasses at ambient conditions. Both methods point to …

Recent advances made by reaction experiments on melting of heavily metasomatized hydrous mantle

Dejan Prelević, Michael W. Förster, Stephan Buhre, Fatma Gülmez, Tobias Grützner, Yu Wang, Stephen F. Foley, Дејан Прелевић, Michael W. Förster, Stephan Buhre et autres

Mantle-derived magmas are traditionally assumed to originate by melting of an upper mantle consisting of uniform spinel- or garnet peridotite dominated by olivine. However, extensive studies of mantle-derived basalts suggest that the mantle is more mineralogically heterogeneous, so that the genesis of …

An in-situ experimental HP/HT study on bromine release from a natural basalt

Tobias Grützner, Hélène Bureau, E. Boulard, P. Munsch et autres

We present the first in-situ partitioning data for bromine between a natural basaltic melt and a coexisting fluid.For this study hydrothermal diamond anvil cell experiments at pressures up to 1.7 GPa were conducted.We combined laser heating to melt the basalt glass with …

The origin of Na-alkaline lavas revisited: new constraints from experimental melting of amphibole-rich metasomes+lherzolite at uppermost mantle pressure

Tobias Grützner, Dejan Prelević, Jasper Berndt, Stephan Klemme

Abstract We present a new experimental dataset for reaction experiments between natural amphibole-clinopyroxene metasomes (hornblendite) and synthetic lherzolite that produced Na-rich alkaline melts. Experiments were conducted at 1, 3 and 4 GPa and 1000–1300 °C. The generated melts range from foidite over …
