dypnienie
Dypnienie is a phenomenon observed in certain geological formations, particularly sedimentary rocks. It refers to a localized thickening or swelling of a rock layer, often appearing as a bulge or dome shape. This thickening is typically caused by the differential compaction of sediments. When a thick, relatively impermeable layer, such as shale or clay, is overlain by a thinner, more permeable layer, like sandstone or gravel, the weight of the overlying sediments can cause the impermeable layer to deform.
The pressure from the overburden compacts the permeable layer more readily, while the impermeable layer resists
