The Osmium Isotope Signature of Phanerozoic Large Igneous Provinces
Geophysical Monograph Series, Page 229-246., 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.

The consequences of crustal melting in continental subduction [PDF]
Lithosphere, 2009 Orogens grow in part by thrusting and burial of continental crust, in some cases, into the mantle by continental subduction. Deeply buried continental crust may partially melt during ascent, adding magma to the overlying continental crust, creating a continental plateau, and accounting for the large melt volumes observed in modern and ancient orogens ...

Geophysical Research Letters, 2022 The mechanisms driving crustal deformation and uplift of orogenic plateaus are fundamental to continental tectonics. Large‐scale crustal flow has been hypothesized to occur in eastern Tibet, but it remains controversial due to a lack of geologic evidence.

Granite magmatism and mantle filiation [PDF]
European Journal of MineralogyCurrent granite magma generation models essentially reduce to two groups: (1) intra-crustal melting and (2) basaltic origin. A mixed, crustal, and basaltic origin and therefore a mantle filiation has been proposed for most granite magma types.

pyMelt: An extensible Python engine for mantle melting calculations
Volcanica, 2022 Modelling the melting of Earth’s mantle is crucial for understanding the distribution of volcanic activity on Earth and for testing models of mantle convection and mantle lithological heterogeneity.

The influence of melting and melt drainage on crustal rheology during orogenesis [PDF]
Journal of Geophysical Research: Solid Earth, 2014 AbstractPartial melting significantly weakens crustal rocks by introducing a low‐viscosity liquid phase. However, near‐concomitant melt drainage can remove this weak phase, potentially reversing the rheological effects such that the strength of a specific lithology depends on when the prograde pressure‐temperature path intersects a melting reaction ...

Melting conditions in the modern Tibetan crust since the Miocene
Nature Communications, 2018 Crustal melting may play a fundamental role in orogenic processes, but quantifying crustal melt remains difficult. Here, the authors combine pressure-temperature paths, electrical conductivity and geophysical data to elucidate the melting conditions in ...
