Traditionally, porphyry deposits were considered to be the result of focussed fluid extraction from large melt-dominated and convecting magma reservoirs (‘magma chambers’) crystallising in the upper crust (Dilles, 1987; Cloos, 2001; Korges et al., 2020). Miarolitic cavities in large ...
Due to its unfavorable rheology, magma with crystallinity exceeding about 50vol.% and effective viscosity > 10 6Pa s is generally perceived to stall in the Earth's crust rather than to erupt. There is, however, irrefutable evidence for colossal eruption of batholithic magma bodies and here ...
The flare-up includes three different geometries of magmatic system: 1) a “mature” type in which multiple eruptible magma bodies sit adjacent to each other in the shallow crust (∼100 MPa) and are in contact with the top of a vertically extensive, heterogeneous mush system; 2) a “...
Granitoids of the tonalite–trondhjemite–granodiorite (TTG) series dominate Earth’s earliest continental crust. The geochemical diversity of TTGs is ascribed to several possible geodynamic settings of magma formation, from low-pressure differentiation of oceanic plateaus to high-pressure melting of mafic...

Continental crust covers ~40% of the Earth’s surface, comprises ~70% of the total volume of crust, and is (on average) intermediate in composition1,2. However, the great majority of mantle-derived magmas are basaltic3and fractional crystallization is not efficient enough to generate the volum...
From plutons to magma chambers: Thermal constraints on the accumulation of eruptible silicic magma in the upper crust In order to provide new insights into the relationship between plutonism and volcanism, numerical simulations involving heat transfer computation were used...

and Yunhe pluton has revealed that the composition of high-silica magmas is influenced not only by crystal-melt segregation within deep magma reservoir but also by in situ crystal-melt segregation occurring within magma reservoirs formed through the aggregation of felsic melts in the shallow crust....
To better constrain the formation of large-volume magma chambers, we investigate the influence of a changing emplacement rate of successive sill injections that form a composite intrusion in the upper crust. A thermal model with an explicit finite difference scheme simulates periods of transient high...
