[¦sīz·mik ri′flek·tər]
(geophysics)
A subsurface profile that is generated by seismic data and indicates a distinctive type of sediment geometry produced by sea-level changes; used to correlate stratigraphic sequences.

The pre-Quaternary basement boundary is visible as the distinct and strong seismic reflector at 155-165 ms TWT.
The strongest reflectors Cm3 and Cm4 seemingly correspond to levels in the Nar Member and Grodingbo Siltstone, where the presence of seismic reflector levels is indicated by lithological boundaries in the Gotska Sandon drill core (Figs 4, 5).
In the paleoceanographic application of seismic profiling we are not primarily concerned with the geometry of the layers; rather, we seek to associate a particular seismic reflector (or group of reflectors) with a particular paleoclimatic or paleoceanographic event.
The region around this fault is apparently devoid of any major resistivity contrasts, and this is interpreted to mean that the fault, or a hydrothermal-alteration zone around the fault, is the seismic reflector.
It may be that the transition between slightly different metamorphic fabrics can generate a seismic reflector.
Austin counters that no one really knows whether or not the Bahama and Blake Plateau are distinct provinces, and even if they were, site 627 still showed that the seismic reflector at the plateau--and, by inference, elsewhere--is made of shallow-water carbonates.
The research targets the method of seismic data processing and seismic data interpretation to delineate seismic reflectors using 2-D seismic and well data.
The sequence R represents the most recent deposits (upper most sequence), and is characterized by variable and irregular seismic reflectors.
