geodynamical

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 雖然通過以往的大量研究,人們對大陸裂開、洋盆擴張、大洋板塊俯沖和“陸?陸”或“弧?陸”碰撞等主要板塊演化過程中的成礦作用有了較系統地了解,但對于板塊碰撞之后陸內過程中的成礦作用了解較少,尚還未建立起系統的模式。
