| Here three main pockmark and mud diapir fields were observed. |
| They contain kilometre-scale blocks of igneous basement rocks, plucked by the rising diapir from the footwall of the fault. |
| The rise of a diapir is self-limiting because its buoyancy decreases as it rises. |
| Of these two mechanisms, Stokes diapir was favoured for many years in the absence of a reasonable alternative. |
| Evidently, the claystone was locally squeezed upwards along the lines of minimum resistance forming a diapir. |
| A well will ultimately test what are believed to be Vicksburg sands developed around and closed on the flanks of a shale diapir. |
