The origin of the Wilson Ridge pluton and its enclaves, northwestern Arizona: Implications for the generation of a calc-alkaline intermediate pluton in an extensional environment
… as well as fractional crystallization. Similar open system processes may be responsible for the production of calc-alkaline intermediate rocks in other parts of the Great Basin. (Abstract shortened with permission of author.).

Documenting Mantle and Crustal Contributions to Flood Basalt Magmatism via Computational Modeling of the Steens Basalt, Southeast Oregon
… about the relative roles that magmatic processes (recharge, assimilation, and fraction crystallization) have in time (upsection), thus yielding estimates of the mantle vs. crustal mass contribution to the magmatic system. While all three processes are shown to be critical at Steens, …

Historic and prehistoric volcanic activity on St Kitts and Nevis, West Indies: Controls on future hazard
… These geochemical analyses have shown that open-system processes dominated the magma storage conditions at both St Kitts and Nevis, and recharges of hot, primitive magma into the reservoirs led to mixing and magmatic differentiation. The geochemistry also showed that rapid crystallization, …

Martian meteorites as windows into planetary volcanism: insights from olivine-phyric shergottite meteorites
… and can provide valuable insight into magmatic processes and the planet's geological evolution. With more meteorites being found every year, researchers no longer need to look only at single meteorites but rather groups, paired based on their crystallisation ages, ejection ages, and …
