Origin of the Low-Iron Igneous Series at Buldir Island, Western Aleutians
AGU 2024
tectonophysics | 13 december 2024
Gene M. Yogodzinski, Ryan Waldman, Owen Jensen, Mi...
The origin of calcalkaline volcanism is key to our understanding of the role of water in the formation and evolution of arc magmas. Volcanism at Buldi...

Space and time variation of mineral dissolution and precipitation around sites of CO2-rich aqueous fluid injection for geologic storage
AGU 2024
mineral and rock physics | 13 december 2024
Peter B. Kelemen, James Andrew M. Leong
A long-standing concern for subsurface CO2 storage in reactive rock formations has been the potential for clogging of pore space with newly formed car...

The H2 generation potential of Earth’s compositionally diverse igneous rocks
AGU 2024
near surface geophysics | 12 december 2024
James Andrew M. Leong, Tucker Ely, Peter B. Keleme...
Addressing the growing demand for clean H2 is crucial for a carbon-free future. Natural H2 can be a clean and cheap alternative to industrially manufa...

Compositional controls on the extent of carbon mobilized from subducted sedimentary rocks
AGU 2024
study of earth's deep interior | 10 december 2024
James Andrew M. Leong, Peter B. Kelemen
In subduction zones, some of the carbon bound in minerals and organic materials are mobilized. The extent to which carbon is extracted from subducting...

SUBAQUEOUS OCEANIC AND CONTINENTAL HYDROTHERMAL SYSTEMS: GEOCHEMISTRY, HYDROLOGY, BIOLOGY, AND STRUCTURE II ORAL
volcanology, geochemistry and petrology | 15 december 2023
James Andrew M. Leong, Juan Carlos de Obeso, Peter...
Serpentinization occurs when water meets ultramafic rocks. It is a ubiquitous process that produces a wide range of redox conditions. A notable exampl...
