| Microseismic monitoring has a role to play because the failure of the rock strata causes microseismic emissions. |
| This interpretation is supported by the arrangement of intervening strata into transgressive and regressive cycles. |
| There are in these strata many faults or irregularities, by which the due range of the strata is thrown out of course. |
| The quarry produces stones of considerable size which are easily detached, the strata being regularly disposed one above the other. |
| Leached residual soil and sediment of overlying strata occur within the dissolution pipes and pits. |
| Instead there was a ragbag of patients from all strata of society being wheeled around looking rather forlorn. |
