Date Created: 2008-02-05

The DRUM (Deep Reflections from the Upper Mantle) 2D seismic reflection profile was undertaken as part of the BIRPS surveys in 1984 offshore north of Scotland. Its aim was to trace to greater depth the ‘Flannan’ reflector, and intra-mantle reflector observed on the MOIST BIRPS survey. In 1984, the DRUM profile was the deepest penetrating seismic reflection profile in the world. Data are in time and amplitude.

BIRPS - DRUM -Flack & Warner 1990 interpretation Interpretation

Date Created: 2008-02-05

In this interpretation (after Flack and Warner, 1990) the presence of Mesozoic basins in and normal faults in the upper the presence of Mesozoic basins in and normal faults in the upper 5 seconds of the DRUM profile are clearly identified. Permian and older sediments (possibly to Torridonian) could account for reflections down to 4 seconds in the basins – particularly in the North Le...

This interpreted line drawing showing the principle high amplitude reflectors (after McGeary and Warner, 1985) and key structural elements and the position of the Moho (after McGeary and Warner, 1985; Morgan et al., 2000) in the DRUM profile from the BIRPS surveys. The line drawing identifies rotated half-graben blocks in the upper crust and reflective lower crust and Moho. Beneath th...
