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 1, 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 1, English, - welded%20ignimbrite
