| Abstract |
The edge of a continental block lies beneath the sea. The outermost part is the continental slope (gradient of about 1 in 15), the top of which lies at a depth of about 75 fathoms or even as low as about 200 fathoms. Between this and the shore there is a region of marginal shelf of low relief, commonly between 4 and 150 miles wide. This, together with the shallow epicontinental seas, such as the North Sea, represents about 13 per cent of the total area of the continental blocks. The history of this region is still little known and geographical coverage is poor. However, the presence of minerals of economic importance and the development of many new techniques have speeded up exploration since the Second World War. There are already some recent reviews of North American shelves (Emery, 1959; Murray, 1961), North Atlantic shelves (Heezen, Tharp and Ewing, 1959; Hill, 1957), more general reviews (Guilcher, 1958; King, 1962), and discussions of relief (Holtedahl, 1959; Jordan, 1962a). The present review dwells for the most part on later results or those not already reviewed, in the fields of methods employed, solid geology especially around the British Isles, sedimentation processes on the open shelf, and the post-Glacial rise of sea level. |
