Eutaxitic texture describes the layered or banded texture in explosive volcanic rocks. It is often caused by the compaction and flattening of glass shards and pumice fragments. Ignimbrites are typically characterized by fist-sized pumice fragments floating in a finer grained matrix but many ignimbrites, however, are still hot when they are emplaced so that the pumice and ash fragments are still plastic and malleable.  1, record 1, English, - eutaxitic%20texture

Lithologies are similar even if welding degrees ranges are spread from loose deposits to eutaxitic facies. Petrological study show quite homogeneous mineralogical assemblages since quartz, feldspar, biotite, amphibole and oxydes dominate the paragenesis.  2, record 2, English, - eutaxitic

Les lithologies sont assez semblables, bien que les degrés de soudure varient beaucoup, allant de produits meubles jusqu'aux faciès eutaxitiques. L'étude pétrologique révèle des assemblages de minéraux assez homogènes, les paragenèses étant dominées par le quartz, le feldspath, la biotite, l'amphibole et des oxydes.  1, record 2, French, - eutaxitique

If sufficiently hot when deposited, the particles in an ignimbrite may weld together, and the deposit is transformed into a "welded ignimbrite, "made of eutaxitic lapilli-tuff. When this happens, the pumice lapilli commonly flatten, and these appear on rock surfaces as dark lense-shapes, known as fiamme. Intensely welded ignimbrite may have glassy zones near the base and top, called lower and upper "vitrophyres, "but central parts are microcrystalline("lithoidal").  2, record 3, English, - welded%20ignimbrite

Many ignimbrites are loose, unconsolidated deposits, but some exhibit welding, giving the ignimbrite the texture of a solid rock mass, hence the terms commonly used to describe these examples: welded tuff and welded ashflow.  3, record 3, English, - welded%20ignimbrite
