overlying rock

基本解释

Igneous intrusions such as batholiths, laccoliths, dikes, and sills, push upwards into the overlying rock, and crystallize as they intrude.
岩基、岩盖、岩堤、岩席等火成的侵入物向表层岩石推进，并在入侵过程中结晶。
This leads to a honeycomb of cavities that eventually collapse due to the weight of the overlying rock layers, leaving the irregular mounds standing.
这一现象会导致地下形成蜂窝状的洞穴系统，并最终由于上覆岩层的重力而崩塌，留下一些不规则的岩石群。
During overlying rock strata being fractured, the surface gas drainage boreholes may be damaged due to ground movement.
在长壁工作面通过的过程中，地面垂直钻孔可能随岩层移动而发生破坏。
