The relationship of geodynamic evolution and deposits formation has been one of important problems focused by geologists in the past twenty years . although we known much about the metallogeny occurred during the main processes such as continent rifting , ocean spreading and plate subducting as well as continent - continent or continent - arc collision , the model of metallogeny occurred after collision has not been established
虽然通过以往的大量研究，人们对大陆裂开、洋盆扩张、大洋板块俯冲和“陆?陆”或“弧?陆”碰撞等主要板块演化过程中的成矿作用有了较系统地了解，但对于板块碰撞之后陆内过程中的成矿作用了解较少，尚还未建立起系统的模式。
