   • Fig. 6. A block of feldspar-bearing sandstone which syneruptively subsided in the Rödern diatreme in the Carboniferous-Permian Saar-Nahe Basin, SW Germany (Lorenz 1971). 1986 October, V.

   • The liquid being sampled from a draining reservoir of density-stratified fluid, such as an erupting zoned magma chamber, is derived from a relatively thin withdrawal layer adjacent to the level of the chamber outlet. This is a consequence of the buoyancy force associated with the density gradient inhibiting vertical motion so that the opportunity for widely separated density levels (compositions) to be tapped and mingled syneruptively is suppressed. 1986 December, Stephen Blake, Gregory N.

   • Despite small individual volumes (less than 1 cubic kilometers dense rock equivalent), each unit represents eruption of a distinct magma batch that was strongly influenced by clinopyroxene, olivine, and plagioclase fractionation. Some of these units are interpreted to have undergone magma mixing pre- and (or) syneruptively. 2023, “Eruptive history within the vicinity of Al Madīnah in northern Harrat Rahat, Kingdom of Saudi Arabia” (chapter C), in Downs, Drew T., Stelten, Mark E., Champion, Duane E., Dietterich, Hannah R., Hassan, Khalid, Shawali, Jamal, editors, Active volcanism on the Arabian Shield—Geology, volcanology, and geophysics of northern Harrat Rahat and vicinity, Kingdom of Saudi Arabia (USGS Professional Paper; 1862-C), Reston, VA: United States Geological Survey, →DOI, archived from the original on 05 Oct 2024:
   • Carbon dioxide is one of the most common magmatic gasses and is often emitted at submarine hydrothermal and eruptive vents (e.g., Chadwick, Cashman, et al., 2008; Lupton et al., 2006). Chadwick et al. (2014) observed CO2 bubbles emerging from the eruptive vents at NW Rota-1 detach from the syneruptively generated sulfur-rich plumes and rise higher in the water column before eventually dissolving. Our observations provide evidence that CO2 appears to behave similarly at Hunga. 2024 August, Sharon L. Walker, Cornel E.
