The role of crustal and mantle sources in the genesis of granitoids of the Antarctic Peninsula and adjacent crustal blocks [PDF]

open access: yes, 2001
Magmatic rocks from the Antarctic Peninsula show marked variations in isotope composition, which reflect changes in the geodynamic evolution of the peninsula through time. Most Antarctic Peninsula granitoids formed as a result of subduction: they fall on

Environmental Effects of Volcanic Volatile Fluxes From Subaerial Large Igneous Provinces

open access: yesGeophysical Monograph Series, Page 103-116., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Sourcing Neo-Acadian Inner Piedmont Granitoids withinthe Southern Appalachians [PDF]

open access: yes, 2022
New whole-rock U/Th/Pb, Sm-Nd and Rb-Sr isotopic data are presented from meta-granitoids, gabbros, and meta-sedimentary rocks within the eastern Blue Ridge, Inner Piedmont, and Charlotte belts of the southern Appalachians.

Batholith recorded mesozoic multistage tectonic evolution of the South china block: A case study of the guandimiao intrusions

open access: yesFrontiers in Earth Science, 2022
South China is a well-known grand felsic igneous rocks province. However, it is still controversial and not well understood whether the Mesozoic tectono-magmatic pattern is dominated by the subduction of the paleo-Pacific oceanic plate. In this study, we
