In the modern Earth, plate tectonics allows for the reworking of surface material (i.e. erosion/weathering – burial – partial melting) in active convergent settings. This process mobilises and drags a substantial volume of mineral-bound volatiles (i.e. CO2, H2O) to lower crustal and mantle depths. Most of these volatiles, chief among them carbon, rapidly find theirContinue reading “Carbon cycle in the (ultra) deep continental crust”

A great triptych of papers by Prof. Marian Holness in Journal of Petrology on convection in tabular intrusions and our work on the Isle of Skye, Scotland

Presentation at the 2022 EGU on melt inclusions in the Adirondacks garnets. ABSTRACT: The Adirondack Mountains, New York State, USA belongs to the Canadian Grenville Province (Darling and Peck, 2016). The rocks exposed in the Adirondacks are interpreted to be the lower plate of a thrust-system at crustal levels during the Ottawan Orogeny (1090-1050 Ma)Continue reading “EGU 2022 – Multiple Melts”
