WebHyaloclastites are defined as glass-rich volcanic rocks formed by lava-water (and lava-sediment) interaction where the lava is shattered into small angular glassy fragments. Figure F10. Igneous lithology naming conventions. Matrix-supported breccias not related to lava flows are described in the Sedimentary tab in DESClogik. Hyaloclastite is a volcanoclastic accumulation or breccia consisting of glass (from the Greek hyalus) fragments (clasts) formed by quench fragmentation of lava flow surfaces during submarine or subglacial extrusion. It occurs as thin margins on the lava flow surfaces and between pillow lavas as well as in thicker deposits, more commonly associated with explosive, volatile-rich eruptions a… Weband with Pleistocene hyaloclastites atop nearby Námaskarð hill, reveal different patterns of alteration depending on water-rock ratio, degree of oxidation, and substrate composition and age.

WebWhile alteration of hyaloclastites under smectite-zeolite conditions proceeds via palagonitization, replacement of basaltic glass by smectite clay, and infilling of clay and zeolites in vesicles, under higher-temperature chlorite–epidote (>240 ∘ C) or epidote–actinolite (>280 ∘ C) conditions, alteration proceeds to an increasing extent by … Web29 sep. 2016 · The process of alteration in the hyaloclastites was thought to require a long time but took only a few years to happen in Surtsey Island that emerged from the sea in an eruption in 1963-67 .

Hyaloclastites are highly variable, altered volcaniclas-tic breccias that form explicitly by severe quench-induced fragmentation of magma interacting with a large volume of external water or ice [26]. However, the term is often applied ambiguously in the literature to any lava fragmen-ted by interaction with water [27]; consequently, it is
