| At Llandovery they rest unconformably upon Ordovician rocks, but in many other places no unconformity is traceable. |
| This series is overlain unconformably by a younger quartzite of similar character, and itself rests upon the crystalline schists. |
| The Moine rocks are overlain unconformably by post-Caledonian, Old Red Sandstone sedimentary rocks. |
| Deposition of the unconformably overlying Red Bay Group was terminated in latest Lochkovian times by renewed sinistral strike-slip faulting. |
| A greatly deformed and metamorphosed older series is unconformably overlaid by a great thickness of younger strata. |
| In Tertiary time, the Batain nappes were unconformably overlain by carbonate and elastic rocks. |
