| Arkley, S L B. 2014. Model metadata report for the Great Glen — Moray Firth GSI3D Faulted Bedrock Model. British Geological Survey Internal Report, OR/14/058. |
The sedimentary sequence consists of 9 geological units:
| Units modelled | Offshore equivalents | ||
| LOCR-SSML | Lower Cretaceous | CRKN-ARG | Cromer Knoll Group |
| JURU-SDSM | Upper Jurassic | HMBG-ARSL | Humber Group |
| JURM-MDSL | Middle Jurassic | FLDN-SMC & JURM-ARSM | Fladen Group – Middle Jurassic Rocks |
| LI-MSLS | Lias,Lower Jurassic | LI-SDAR | Lias Group |
| NRS-SDBC | Permian-Triassic | PRMT-SDAR | Permian and Triassic Rocks (undifferentiated) |
| UDEV-SCON | Upper Devonian | UORS-SDST | Upper Old Red Sandstone |
| MDEV-SCON | Middle Devonian | MDEV-COSD | Middle Devonian (undifferentiated) |
| LORS-CSSM | Lower Devonian | ||
| ORS-CSSM | undifferentiated Devonian,slices within fault zones |
The onshore geology is based on the BGS 625 000 geological map. The offshore geology is based on the BGS 250 000 map. All units are labelled with BGS LEX-RCS codes, see Figures 2 and 3.
Geological units modelled are as used in the GB_3D sections on which the model is based. Offshore units were merged into their onshore equivalents, as shown in Table 1.
