Myrmekite-bearing gneiss from the Szeghalom dome (Pannonian basin, Se Hungary) : part I. : myrmekite formation theories

Myrmekite is a common textural feature in many magmatic and metamorphic rock types. Nevertheless, there are several theories concerning its genesis; myrmekite may form by igneous crystallization, solid state exsolution, progressive or retrograde metamorphism, metasomatism or even as a result of complicated deformation mechanisms. In this paper a brief compilation of these models is given and classified by myrmekite forming processes instead of rock types or minerals involved
