Massive production of abiotic methane during subduction evidenced in metamorphosed ophicarbonates from the Italian Alps

Nature Communications, 2017
Alteration of ultramafic rocks plays a role in hydrocarbon production, but little is known about this process at depth. Here, the authors provide evidence that alteration of carbonated ultramafic rocks at high-pressures are an important source of abiotic

Olivine-chrome-spinel equilibrium in chromitites and ultramafites of Rai-Iz massif, Polar Urals

Литосфера, 2016
Olivine and chrome-spinel compositions from chromitites and ore-bearing metamorphosed ultramafic rocks of Rai-Iz massif were compared. It was established that olivine and spinel ferruginosity are directly proportional and increase monotonically from ...

Baddeleyite and zircon U-Pb ages of the ultramafic rocks in Chigu Tso area, Southeastern Tibet and their constraints on the timing of Comei Large Igneous Province

China Geology, 2020
: A suite of ultramafic and mafic rocks developed in the Chigu Tso area, eastern Tethyan Himalaya. Baddeleyite and zircon U-Pb ages acquired by SIMS and LA-ICP-MS from olivine pyroxenite rocks in the Chigu Tso area are 138.9±3.0 Ma and 139.0±1.9 Ma ...

Ultramafic Melt Viscosity: A Model

Earth and Planetary Science Letters
A non-Arrhenian model for the Newtonian viscosity (η) of ultramafic melts is presented. The model predicts the viscosity of ultramafic melts as a function of temperature (T), pressure (P), H2O content and for a range of melt compositions (70 < Mg# < 100).

Plant mineral nutrition on ultramafic rocks of New Caledonia

, 2023
International audienceIn New Caledonia, the environmental heterogeneity on ultramafic rocks is a major driver of plant diversity. Here, the foliar mineral composition of numerous species was analysed to (1) explore plant mineral nutrition in different ...
