The Rockall High, Hatton Basin and Hatton High
The Rockall Plateau is an elevated topographical subsea feature, rising above sea level only at the islet of Rockall. It is a microcontinent, underlain by continental crust, bounded to the west, NW and south by North Atlantic oceanic crust, and to the east by the thinned continental crust and oceanic crust underlying the Rockall Trough. The Rockall Plateau comprises the upstanding topographical features of Rockall Bank and Hatton Bank, separated by the Hatton Basin. The Edoras Bank forms the southern boundary of the Hattion Basin, connecting the Rockall Bank and Hatton Bank (Fig. 170). Rockall Bank overlies the Rockall High, formed by continental (Precambrian) basement. Hatton Bank overlies the Hatton High, apparently formed by Palaeozoic? and Mesozoic sediments. In the intervening Hatton Basin (formerly the Hatton-Rockall Basin), a thick section of presumed Mesozoic sediments underlies a sedimentary Cenozoic section.
Figures & Tables
This Special Report comprehensively describes the stratigraphy and correlation of the Tertiary (Paleogene-Neogene) rocks of NW Europe and the adjacent Atlantic Ocean and is the summation of fifty years of research on Tertiary sediments by Chris King. His book is essential reading for all geologists who deal with Tertiary rocks across NW Europe, including those in the petroleum industry and geotechnical services as well as academic stratigraphers and palaeontologists.
Introductory sections on chronostratigraphy, biostratigraphy and other methods of dating and correlation are followed by a regional summary of Tertiary sedimentary basins and their framework and an introduction to Tertiary igneous rocks. The third and largest segment comprises the regional stratigraphic summaries. Regions covered are the North Sea Basin, on shore areas of southern England and the eastern English Channel area, the North Atlantic margins (including non-marine basins in the Irish Sea and elsewhere) and the Paleogene igneous rocks of Scotland.
