摘要
立足于准噶尔、天山地区的古亚洲多岛洋具有典型的多旋回、软碰撞、弱造山的特点 ,应用“比较解剖学”的原理 ,从全球动力学角度出发 ,从历史分析入手 ,运用多学科、多层次的剖析 ,准确把握各地质历史时期的区域地质背景。通过野外对地质露头的有效观察 ,对各构造相单元的时态、相态、位态和序态进行研究 ,揭示大陆造山带的形成演化 ,从而建立造山带演化模式的“四维蓝图”
Base upon the characteristics of typical multicyclicity、soft collision and weak orogeny of ancient asian archipelagic ocean,applying to comparative anatomy principle,on the view of global dynamics,combining with historical and polysubject,multi layered analysis,and exactly grasping regional geological setting of every geological historical stage,and reveal formation and evolution of continental orogeny,the authors make out a four dimension blueprint of orogenic evolution pattern by observing geological outcrops in the field and study on the time,facies ,location and sequence condition of each unit.
