“…Buchner and Schmieder (2010) and Meyer et al (2011) have proposed that the Ries outer suevite was deposited as an impact-generated equivalent of an ignimbritic surge deposit, with elongate melt fragments (flaedle) showing preferred (outward radial) orientation. More recent interpretations of the crater or fallback suevite propose an origin via explosive molten fuel-coolant interaction (MFCI, for example, El-Genk et al 1981) between impact melt and water St€ offler et al 2013), as has been suggested for components of the Onaping Formation, which lies on top of the impact melt rocks (the Sudbury Igneous Complex) at Sudbury (Grieve et al 2010;Osinski et al 2016).…”

The interface between impact melt rocks and underlying footwall lithologies within the Manicouagan impact structure is defined by a zone of dynamic mixing (<20 m thick). This zone transitions as a continuum from clast‐free to clast‐bearing impact melt rocks, through melt‐bearing breccias to melt‐free breccias. Field observations; microscopy; and major, trace, and rare earth element analysis indicate that the breccias are derived by blending two endmembers during the impact process: impact melt and brecciated footwall. The product is a basal breccia sequence, which locally includes the rock type referred to as suevite. In this occurrence, the suevite is a submelt sheet variety, in contrast to similar lithologies that are developed atop impact melt sheets, or beyond crater rims. Dynamic mixing between impact melt and basal clastic material at Manicouagan is attributed to the initial high‐speed centrifugal outflow of superheated, low viscosity impact melt over underlying fractured and fragmented footwall, and its centripetal return during the earlier stages of the crater modification process. The interaction of two fluids (melt with a mobilized granular medium) possessing contrasting densities, and moving at different velocities, can facilitate shear instabilities and turbulent mixing that may be characteristic of Kelvin–Helmholtz behavior.

“…From a regional perspective, European researchers contributed most to the science of hydrovolcanism (41.6%), followed by researchers from North America (26.2%), Oceania (Australia and New Zealand; 18.2%), Asia (14%), South America (3.7%) and Africa (2.3%). The contribution of Europe is shared by 16 countries, from which by the number of publications Italy (15), United Kingdom (14), Germany (11), Spain (9), Russia (8), Norway (7) and France (5) can be designated. From North and Central America, numerically United States has contributed the most (34 articles), followed by Costa Rica, Canada (7) and Mexico (6).…”

“…The first observations of nuclear testing (since 1945 onward) provided an understanding of the transport and depositional processes of explosive hydrovolcanism, whereas further key observations were made during the 1958 Capelinhos, 1963Surtsey, 1965Taal and 1977 Ukinrek volcanic eruptions [6][7][8][9][10][11]. During the 1970's the physics of explosive interactions between magma and water was studied using vapor (steam) explosions as analogues These, also called molten fuel-coolant interaction (MFCI), have been observed in the nuclear, smelting and chemical industries [12][13][14][15][16].…”

Hydrovolcanism is a type of volcanism where magma and water interact either explosively or non-explosively. The less frequently used term, hydromagmatism, includes all the processes responsible for magma and water interaction in a magmatic system. Hydrovolcanism is commonly used as a synonym for phreatomagmatism. However, in recent years phreatomagmatism appears more in association with volcanic eruptions that occur in shallow subaqueous or terrestrial settings and commonly involves molten fuel-coolant interaction (MFCI) driven processes. Here a revised and reviewed classification scheme is suggested on the basis of the geo-environment in which the magma-water interaction takes place and the explosivity plus mode of energy transfer required to generate kinetic energy to produce pyroclasts. Over the past decade researchers have focused on the role hydrovolcanism/phreatomagmatism plays in the formation of maar craters, the evolution of diatremes and the signatures of magma—water interaction in the geological record. In the past five years, lithofacies-characterization is the most common approach to studying hydrovolcanism. By far mafic monogenetic volcanic fields generated the greatest number of research results. Significant knowledge gaps are identified, especially in developing tools to identify the textural signatures hydrovolcanism leave behind on eruptive products and exploring the role of hydrovolcanism in the growth of intermediate and silicic small volume volcanoes.
