When applying multiple suppression techniques to the processing of seismic data, the real objective is to minimize the remnant multiple energy. Here, we propose a method which utilizes multiple suppression techniques to develop "difference' and "confidence' sections which are superimposed on processed data as colour overlays. Using a deep seismic data example, with targets around 10 s (30 km), we demonstrate that these sections can be used in a strategy for comparing and evaluating the reliability of multiple suppression techniques. -from Authors
Flack CA, Klemperer SL, McGeary SE, et al., 1990, Reflections from mantle fault zones around the British Isles, Geology, Vol: 18, Pages: 528-532, ISSN: 0091-7613
British Institutions Reflection Profiling Syndicate (BIRPS) deep seismic reflection surveys show that the upper mantle around the British Isles is reflective, exhibiting discrete, isolated reflecting zones within an otherwise seismically transparent mantle. There are 20 known occurrences of reflectors within the upper mantle across the continental shelf of the British Isles, many delimited by intersecting or closely spaced profiles. Most of the mantle reflectors have similar reflection characteristics: they dip 10° to 30° and are thin (∼0.5 s [∼2 km]) and discrete. The geologic history of the continental shelf around the British Isles (an area 1000 x 1000 km) is complex, and the tectonic settings of these reflectors vary. Each mantle reflector is associated with a major zone of deformation in the crust. This association, the dips of the reflectors, and their high reflectivity all indicate a structural origin. The BIRPS mantle reflectors include probable early Paleozoic thrusts and Mesozoic normal faults. In contrast to BIRPS data, deep reflection profiles in other areas of the world, in a variety of geologic settings, have only rarely image reflectors within the upper mantle © 1990 Geological Society of America.

BIRPS deep seismic reflection data collected on the western United Kingdom continental shelf show the existence of a wide variety of sedimentary basins, most of which originated during Palaeozoic-Mesozoic crustal extension. Symmetrical interior-fracture basins are numerous, but more complex basins are also common and show the importance of fault reactivation and the influence of pre-existing structures on basin development. All of the major basement-penetrating faults are interpreted as having been reactivated. They do not visibly cut through the entire crust and into the upper mantle. The crystalline crust thins dramatically beneath the basins indicating local crustal extensions of up to 60%, although regional extension is less than 30%.The typical BIRPS profile shows a highly reflective lower crust sandwiched between an unreflective upper crust and upper mantle. This pattern of reflectivity appears to be characteristic of deep seismic data collected from within extended regions. The relatively small amount of extension which has affected this region suggests that the highly reflective lower crust is more likely to be due to lithological variation formed by mafic igneous intrusion and underplating during crustal extension than to-extensional ductile fabrics within the lower crust. © 1987 The Geological Society.

BIRPS has successfully imaged both the major structures and sedimentary basins of the upper crust and the important features of the lower crust and Moho. The most exciting features seen on the BIRPS profiles, however, are the highly reflective structures in the mantle. One of these mantle reflectors can be traced from the Moho to a depth of at least 80km within the continental lithosphere.- from Authors
