1916 Bull. de la Comm. Géol. de la Finlande 9 xlviii. 120 Myrmekitic intergrowths may occasionally originate like the minerals crystallising in a molten magma, not as crystalloblastic minerals.
1944 Q. Jrnl. Geol. Soc. 99 118 The plagioclase is sericitized and its larger plates show myrmekitic margins.
1972 R. Galopin & N. F. M. Henry Microsc. Study Opaque Minerals viii. 195/2 Some of them [sc. forms of mineral intergrowth] resemble the myrmekitic texture found in granites.
1989 Nature 6 Apr. 498/1 Some chalcopyrite is present, but mostly as myrmekitic inclusions or as fine-grained replacement textures described as ‘chalcopyrite disease’.
