1952 M. I. Goldman in Mem. Geol. Soc. Amer. 50 7 Although Royer uses ‘epitaxie’ to designate continuous crystallographic orientation between added material and its nucleus, etymologically it means merely ‘orientation upon’. It is desirable to distinguish between the relation of added crystalline material with the same orientation as the nucleus, for which I propose syntaxy and syntaxial.
1953 G. Donnay & J. D. H. Donnay in Amer. Mineralogist 38 939 Ungemach's definition of syntaxic intergrowth seems to be unduly restrictive, as this kind of intergrowth is found to occur also with constituent substances that are chemically different. We therefore propose to abandon the condition of identity of chemical compositions. Henceforth we shall use the term syntaxy in this extended meaning.
1973 Jrnl. Solid State Chem. 6 396 Ordered syntaxy and polytypism..give a regular repetition of structural or chemical elements over very long crystalline distances.
1975 Amer. Mineralogist 60 351 Intimate syntaxy between parisite, synchisite, roentgenite, and bastnaesite was quite commonly observed even on a very fine scale.
2005 C. W. Passchier & R. A. J. Trouw Microtectonics (ed. 2) vii. 191/1 The special situation where the crystal lattices of both minerals are parallel is known as syntaxy.
