摘要: 通过对郯庐断裂带莒县招贤~宿迁晓店段断裂变形产物进行定向采集、原态固结,对其进行显微观测,结合宏观和实验岩石学资料分析,归纳出反映该活动断裂段运动特性的微观粘滑与蠕滑标志,并对有关问题进行了讨论。

Abstract: Based on orientated sampling of deformation prod ucts in Juxian Zhaoxian~Suqian Xiaodian of the Tancheng-Lujiang fault zone, undisturbing and indurating sampling, the micorscopic ob-servation has been conducted, along with results of rock-breaking test and microsopic analysis.The authors come to conclusion of microscopic marks of stick slippage,reprsentative of kinetic characteristics of the fault zone. Outlined some problems in this regard have been discussed aswell.

Key words: Tanchen-Lujiang fault, Microfracture, Viscous slip, Creep model, Creep, Microsturcture
