Folyadékkéreg

Folyadékkéreg, meaning "liquid crust" in Hungarian, is a geological term used to describe a phenomenon where a layer of molten or semi-molten rock exists beneath a solid crust. This subsurface magma chamber can be found in various geological settings, often associated with volcanic activity. The presence of liquidéreg indicates a dynamic and active Earth's mantle.

The depth and composition of a folyadékkéreg can vary significantly. It may be a relatively shallow layer close to the surface, feeding volcanic eruptions, or it could be a deeper feature contributing to tectonic plate movement. The material within the folyadékkéreg is typically basaltic or andesitic magma, but it can also contain a mix of solidified rock fragments and dissolved gases.

Understanding folyadékkéreg is crucial for predicting volcanic eruptions and seismic events. Geophysical methods such as seismic tomography and ground-penetrating radar are used to detect and map these subsurface magma bodies. Studying their behavior can provide insights into the processes driving volcanism and plate tectonics, contributing to our broader understanding of Earth's internal structure and evolution. The term is primarily used in Hungarian geological literature.
