Rights to exploit these resources are disputed between the United Kingdom, Ireland, Iceland and the Faroe Islands (a possession of Denmark). The record can be used to correlate polarity reversals to marine isotope Book Title Book Series Analysis of the microtopography of the area has given information on Post-Palaeogene sedimentation processes. Originally thought to be oceanic crust it is now generally considered to be highly stretched continental crust, although some groups of researchers continue to favour either oceanic or transitional style crust, particularly at the southern end of the basin. In the NE corner of Rockall Plateau, Rockall Island is made of aegirine granite of Lower Eocene age 1,2 .

Peel away the ocean, and you will find that Rockall is the tip of a vast submerged plateau, 450 kilometer in length and around 500 to 1000 meters deep which in the Atlantic Ocean counts as shallow. A further 22 secondary stations across the various strata have been generated to provide a source of additional stations and/or alternatives should any primary station prove unfishable. Rockall is one of the summits of a submerged reef called Hellen’s Reef (extinct volcano), the only one always above the sea-level.

The discoveries show that, at least locally, there is a working petroleum system. If the address matches an existing account you will receive an email with instructions to reset your password.

The surrounding elevated seabed is called the Rockall Bank, lying directly south from an area known as the Rockall Plateau. (or is it just me...), Smithsonian Privacy The record section has been modelled using synthetic seismograms to obtain a well‐constrained velocity/depth structure down to about 4 km below the top of the dipping reflector sequence. As such, it may contain errors. ODP Site 982 (at 57.52°N, 15.87°W, 1135 m water depth) is located in the Hatton-Rockall Basin, a small depression on the Rockall Plateau (Figure 1).
