| This results in a long and gentle backslope called a dip slope that conforms with the dip of resistant strata, called caprock. |
| When this CO2 finally reaches the upper part of the zone, further movement will be blocked by a 950m thick layer of impermeable mudstone, or caprock of the formation, forming a natural seal. |
| In Gabon, Comilog S. A. opencast mines a rich tabular manganese deposit, located under thin caprock and formed by superficial weathering of volcano-sedimentary rocks. |
| The authors argue that even quakes that are imperceptible to humans can damage the caprock seal of CO2 repositories enough to release the gas back into the atmosphere. |
| At a large scale, caprock characterization requires at least seismic profiles to identify lateral continuity. |
| As the caprock erodes, the underlying limestone is exposed to the runoff water that drains from the remaining area of the plateau. |
