Lithological Description: |
In the type well of the Dornoch Formation (14/25-1), and most other Outer Moray Firth sections, the Upper Dornoch Sandstone unit is made up of a series of upward-coarsening, siltstone-sandstone cycles, generally with a low-gamma, poorly consolidated sandstone at the top. Individual cycles typically range from 10 to over 50 m in thickness. In some Northern North Sea sections (e.g. 3/3-8) the coarsening-upward motif is less pronounced, and the unit generally consists of an alternation of clean, poorly consolidated sandstone and silty mudstone. |
