Thermal transient PDC behavior induced by topographic drops: A test case at Mt. St. Helens, USA

Schematic cartoon summarizing the transient process induced by a topographic drop. A recirculation zone with a typical transient time (τ) forms when the size of the current (Η) is comparable with the drop height (J). Such configuration alters the PDC internal flow structure, as exemplified by temperature (Τ) and velocity…

Short-term magma-carbonate interaction: A modelling perspective

Figura 1. Conceptual drawing of short-term magma-carbonate interaction. a) The magma can pick up fragments of carbonate rocks as it rises to the surface; b) the melt shell around the clast is contaminated in CaO and CO2 and CO2-rich gas bubbles nucleate and grow at the melt-clast interface; c) the…
