摘要: 辽东半岛南端的大连半岛是一个刚性断块。其上无活动性大断裂穿过,老断裂多而规模小,在地貌和新地层上无新活动表现。穿越它们的第四纪河、海阶地均平行分布,无明显的垂直或水平错位。整个半岛第四纪以来作整体断块上升。半岛上的小震稀少零星,属刚性断块地壳应力作用下的微破坏活动。位于其上的大连市是安全的,无发生破坏性大震的危险。

Abstract: Geomorphological investigation and survey of faults are conducted to identify whether the important, industrial harbour city . Dalian,which is situated on the Dalian Peninsula,is tectonical-1y safe(Fig. I).The authors' research provides a postive answer ,based on the following morpho- tectonic features: The Dalian Peninsula is a rigid large fault block .consisting of the Upper Proterozoic Sinian formation (quartz sandstones,siliceous slates and limestones)without any considerable active fault to cut through it. Although there is a complicated network of old faults developed in the block。 these faults are found to be of small dimension and to have no any evidences for their recent acti-vation on landforms and in Quaternary strata.
