造山带异源浆混花岗岩理论与方法研究

1：5万花岗岩填图方法在区调工作中推广以来，在造山带花岗岩调查实践中，由于造山作用及过程的复杂性，花岗岩浆的多源及多样性，使同源岩浆演化理论及方法遇到了难题。文章在新一轮1：25万造山带试点图幅，在对同源岩浆演化理论及方法的适用性进行探索的同时，提出了异源浆混理论指导造山带内部浆混花岗岩（H型花岗岩）的填图方法。并就异源浆混花岗岩鉴别标志等作了系统总结，提出了浆混组合、浆混单元、浆混体，填图的理论方法体系；给予了浆混花岗岩明确的定义。

Research on theory and method of orogen heterologous magma-mixed granites

1：50000 granite mapping method has been promoted in regional survey for years, when it is applied to granite survey in orogen, some problems about comagmatic evolution theory and method has come out because of the complexity occurred during orogeny and different sources with diversities of granite mag- ma. Inhence, a new orogen pilot mapping method of 1 ：250000 scale has been put forward, in which the application of comagma evolution theory and method has been discussed as well as heterologous magma mixture theory has been applied to guide the mapping method for interior magma-mixed granites in orogen （H type granite） at the same time. It has systematically concluded the identificating indicators for heterologous mag- ma-mixed granite, and raised a mapping theory and method system for magma-mixed combination, magmamixed units and magma-mixed body. A specific definition has been created for magma-mixed granites.
