摘要

///Leucocratic veins are widely distributed in the Fuping Complex, North China Craton, which demonstrates the intensive migmatization. The migmatization was generally described to the metasomatism, pressure solution or fluid-absent partial melting, which are not consistent with the actual petrographic textures.  Therefore, metamorphic reaction of the Fuping Complex, resulting from migmatization, may include both melting o dissolution of feldspathic minerals and chemical transformation of one hydrous mineral （e. g. , biotite） t another one （e. g., hornblende）. The most crucial mechanism of migmatization of the Complex wa dominated by water-fluxed melting or fluid-bearing partial melting, with pressure solution or fluid-absent anatexis as secondary factor. oft-com:office:office" />
