崩塌是较陡斜坡上的岩土体在重力作用下突然脱离母体崩落、滚动、堆积在坡脚（或沟谷）的地质现象。崩落在坡脚的物质称为崩塌体。

此处崩塌物中可见大量平直节理裂隙面，还可见岩石原生沉积层理现象。堆积在坡脚的巨大滚石为官草湖组凝灰质砾岩，沿着节理裂隙面崩塌，形成平直整齐的截面，似被电光雷劈而成，故而得名“雷劈石”。

Collapse is a geological phenomenon that the rock and soil masses on the steep slope suddenly break away from the mother rock under the action of gravity, fall or roll down and accumulate at the toe of slopes. The material falling at the foot of the slope is called collapse body.

There are a large number of flat joints (fissures) planes and primary sedimentary beddings in the collapse body. The huge Rolling Stones piled at the foot of the slope were tuffaceous conglomerate of Guancaohu Formation, which collapsed along joints and fissures and formed flat and neat plane, which seemed to be struck by lightning, so it is called Lightning striking stone.
