摘要： 在造山带研究中，洋壳俯冲过程和陆壳碰撞造山时限是全球造山带研究的重要内容。磨拉石是研究造山带洋壳俯冲过程和陆壳碰撞造山时限的关键性因素之一。通过对黑龙江省造山带的深入研究，认为从造山带角度分析，磨拉石研究的理论意义在于重塑造山历史，即磨拉石不仅能够限定地块边缘洋盆关闭时限，还可以反演造山带洋壳后退式俯冲造山期次（洋陆转换阶段）。分析结果对于研究磨拉石和洋壳俯冲造山过程（洋陆转换过程）有一定的指导意义。

Abstract: In the study of orogenic belts，oceanic crust subduction orogenic process and continental crust collision orogenic time are important contents in the study of orogenic belts around the world. Molasse is one of the key factors to study oceanic crust subduction orogeny and continental crust collision orogeny in orogenic belt.Through the in-depth study of the orogenic belt in Heilongjiang Province，it is believed that the theoretical significance of the study of Motolite is to reconstruct the mountain history from the perspec⁃ tive of the orogenic belt，that is，Motolite can not only limit the closing time of the ocean basin at the edge of the block，but also can invert the recessional subduction orogenic stage of the ocean crust in the orogenic belt (the stage of the ocean-land conversion).The analysis results have certain guiding significance for study⁃ ing the process of moralite and oceanic crust subduction orogenesis (the process of land-ocean conversion).

Key words: orogenic belt, oceanic subduction orogenic molasse, continental crust collision orogenic molasse
