The principal direction of small-scale movement is from a shale or clay to a sandstone or other permeable bed . 小范围运动主要从页岩或粘土岩向砂岩或其他渗透性地层中运动。
Such thickening is due to the relative noncompactibility of the sandstone of the bar as compared with the enclosing shale . 这种增厚是由于砂洲砂岩与其周围的页岩具有不同的不可压实性造成的。
The effectiveness of pressure seals in the subsurface may be evaluated by making a calculated fluidpressure profile of the overlying shales . 在地下，压力封闭的有效性可以通过计算上层页岩的流体压力剖面来估计。
Shale that has been subjected to great pressure from overlying masses of rock or through movements of the earth's crust may be metamorphosed into slate . 页岩受岩石覆盖物或地壳运动造成的巨大压力，可能变质，成为板岩。
