Hybrid flow sills: A new mode of igneous sheet intrusion

Abstract:

Three-dimensional (3-D) seismic mapping of the Vigra sill complex has revealed a series of shallow level lobate sills. This complex was emplaced ca. 55 Ma as part of the igneous activity associated with breakup of the northeast Atlantic margin. The complex consists of discordant sheets, some of which are remarkable in that they have an axial seismic amplitude anomaly along their lengths. The anomalies are interpreted as evidence for the development of magma tubes that formed in the subsurface...
