1886 Proc. Amer. Acad. Arts & Sci. 1885–6 21 498 On different sections of meteorites Widmanstättian figures and Neumann lines can be exhibited in every gradation, from the broadest bands to the finest markings.

1914 Jrnl. Soc. Chem. Industry 15 Aug. 791/2 The Neumann lamellæ occurring in any given grain are parallel to not more than 6 planes corresponding to the crystalline orientation of the grain itself.

1922 Chem. Abstr. 16 3845 (heading) Neumann bands as evidence of action of explosives upon metal.

1946 Jrnl. Iron & Steel Inst. 154 129 p/1 The Neumann band is primarily a shearing or faulting movement operating along the pre-existent planar disjunctions of the mosaic structure, and..as a secondary operation twinning may be completed, as is known to be possible in ferrite.

1966 C. R. Tottle Sci. Engin. Materials iii. 64 In alpha iron (b.c.c.) impact loading at room temperature can produce shear twins, called Neumann bands (which are found, incidentally, in metallic meteorites).

1986 J. G. Burke Cosmic Debris iv. 130 Scientists now accept that almost all Neumann bands [in meteorites] were formed by the shock of a long past cosmic event, though a few might have been the result of entry into the atmosphere.

1999 H. Y. McSween Meteorites (ed. 2) vi. 196 (caption) This cut shows Neumann lines formed by shock deformation, but is otherwise featureless.
