| 摘 要： | 将西武夷地区的加里东花岗岩划分为早奥陶世麻姑山超单元、中晚奥陶世付坊超单元、中晚志留世棠阴超单元和晚志留世鹅婆超单元 ,它们构成武夷山超单元组合 (序列 )。分别与剪切深熔作用有关的花岗质片麻岩、俯冲熔融作用的浅色花岗岩、伸展热隆作用的混合花岗岩和走滑作用的正长花岗岩 ,产生于加里东造山旋回的碰撞前期—主碰撞期—主碰撞后—同碰撞的后期。由此反演出区内的加里东造山作用过程是早期挤压—主期挤压—有限伸展—区域走滑的 4阶段模式。

| Abstract: | Caledonian granite in the
western Wuyi area is divided into the Early Ordovician Magushan superunit, Middle-Late
Orodvician Fufang superunit, Middle-Late Silurian Tangyin superunit and Late Silurian Epo
superunit. The Wuyishan superunit association (sequence) made up of the above-mentioned
superunits occurred with shear anatexis-related granitic gneiss, subduction fusion-related
leucogranite, extensional thermal uplift-related migmatitic granite and strike
slip-related syenogranite respectively in the early collision stage, main collision stage,
post-main collision stage and syncollision stage in the Caledonian orogenic cycle. The
Caledonian orogenic process of the area deduced backward thus may be expressed by a
four-stage model of early-stage compression-main-stage compression-finite
extension-regional strike slip. |
