Explores the complex physico-chemical processes involved in active volcanism and dynamic magmatism
Understanding the magmatic processes responsible for the chemical and textural signatures of volcanic products and igneous rocks is crucial for monitoring, forecasting, and mitigating the impacts of volcanic activity.
Dynamic Magma Evolution is a compilation of recent geochemical, petrological, physical, and thermodynamic studies. It combines field research, experimental results, theoretical approaches, unconventional and novel techniques, and computational modeling to present the latest developments in the field.
Volume highlights include:
* Crystallization and degassing processes in magmatic environments
* Bubble and mineral nucleation and growth induced by cooling and decompression
* Kinetic processes during magma ascent to the surface
* Magma mixing, mingling, and recharge dynamics
* Geo-speedometer measurement of volcanic events
* Changes in magma rheology induced by mineral and volatile content
The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals.
