造山带古海洋恢复的思路和研究方法

造山带由于存在着构造学、地层学诸多方面的造山作用和改造作用，在时空结构上，不但失序，而且移位，因而古海洋恢复使用传统方法即正序方法，不但行不通，而且十分不当。反序方法最具针对性，是造山带古海洋研究中不可缺少的工作思路和方法。

Reversed Order: A New Method for Restoration of Ancient Ocean in Orogenic Belt

Orogenic belt is often a complicated and densely compressed tectonic unit,and has recorded multi-phases of oceanic basin spreading and subduction and also orogenic processes of convergence and collision of several landmasses.Due to multiple tectonic and stratigraphic reworking factors, orogenic belts have very probably experienced sequence lacking and displacement in the history of formation. Therefore, for restoration of ancient oceans in the belts, traditional method, that is, ordered method will come to incorrect conclusions, which will let us misunderstand the processes of the orogenic history. Here, the authors suggest reverse ordered method, and believe that this method is just the correct way of solving the ocean restoration problem and thus very useful in such studies.
