青岛榴辉岩的变形特征及其构造抬升问题

DEFORMATIONAI CHARACTERISTICS AND TECTINIC UPLIFT OF THE ECLOGITES IN QINGDAO

摘要:

青岛榴辉岩具有复杂的变形特征，包括宏观的褶皱变形和微观的矿物变形。它们是榴辉岩形成环境和构造抬升的直接证据。本文结合对岩相学和地球物理资料的分析，认为早期的伸展作用和后期的挤压作用以及剪切逆冲作用是青岛榴辉岩抬升的主要动因。

Abstract:

The eclogites in Qingdao have complex deformational charact-eristics which inelude macroscopic fold-deformation and microcosmic mineral deformation,These are the direct evidence to analyse formatioual envi-ronment and tactonic uplift of the eclogites.Research indicates that early stage extension and late stage compression and shear-thrusting appear to be the main causes in the uplift of the eclogites in Qingdao.
