1802 J. Playfair Illustr. Huttonian Theory 283 The line of separation..has, on the whole, been marked out with great precision; and, though the stones have been firmly united, or, as one may say, welded one upon another, yet, when a fresh fracture was obtained, the stratified and unstratified parts have rarely failed to be distinguished.

1899 J. P. Iddings in A. Hague et al. Geol. Yellowstone Nat. Park ii. x. 406 The mass is compact of glass, but it consists of irregularly shaped streaks and patches of different color. These twist and curve about one another and appear like a perfectly welded mass of strips or ribbons and irregular fragments of variously colored glass.]

1909 J. P. Iddings Igneous Rocks I. i. viii. 333 These examples of welded pumice are from rhyolitic lavas in the Yellowstone National Park.

1935 Trans. Amer. Geophysical Union 309 Although commonly and perhaps generally associated with deposits of light~colored volcanic ash of rhyolitic composition, the welded tuff is not confined to this association but occurs also on older rocks.

1962 E. A. Vincent tr. A. Rittmann Volcanoes ii. 80 Ignimbrites, or welded tuffs, are formed in enormous quantities from overflowing glowing clouds in fissure eruptions of very acid magmas. The incandescent ash particles are intimately fused to one another and attain a largely pseudoliquid state, especially in the deeper portions of the deposit, so that the massive rock which results often shows columnar jointing and is easily confused with a rhyolitic lava.

1976 Jrnl. Geol. Soc. 132 125 The contact of the slump sheets with the overlying mega-beds is welded, i.e. depositional fit is present.
