Geological significance of two lineations in ductile shear zone
Abundant deformation phenomena in ductile shear zones record important information of shear de-formation process.Lineation is a common and important observation element in ductile shear zones,which can provide key clues for the formation and evolution of shear zones.Through field work observation,the characteristics,formation reasons and observation methods of two typical lineations(wrinkle lineation and intersection lineation)are summarized,and the shear movement direction of ductile shear zone is predicted.The research shows that the comprehensive judgment of C-foliation and multiple sections perpendicular to C-foliation should be carried out to avoid the misjudgment of the direction of shear movement due to the confu-sion of wrinkle line and scratch.
