The area of the Jan Mayen Ridge and the Icelandic Plateau in which Sites 346 through 350 were located is shown in Figure 1. The division of this area into the eight provinces shown in Figure 1 has been made by Gr^nlie and Talwani (in preparation), principally on the basis of earlier work by many authors including Johnson et al. (1972) and Talwani and Eldholm (in press). Morphologically regions 1, 2, and 3 form the Jan Mayen Ridge. Region 1 is an area of a magnetic quiet zone; it is in this area that Johnson and Heezen (1967) described the presence of stratified sediments. Talwani and Eldholm (in press) suggest that area 2 is a structural continuation of the Jan Mayen Ridge even though the magnetic anomalies are somewhat more disturbed here. Although area 3 morphologically forms a part of the Jan Mayen Ridge, it is believed by Talwani and Eldholm (in press) to have been created by seafloor spreading contemporaneously with the Norway Basin to the east. Area 5 contains the anomalies associated with the present center of spreading in this area, the Iceland-Jan Mayen Ridge (also known as the Kolbeinsey Ridge). Johnson et al. (1972) have suggested that an intermediate axis of spreading, now extinct, lies between the Iceland-Jan Mayen Ridge and the Jan Mayen Ridge. The magnetic anomalies associated with this extinct axis lie in the area 4. The anomaly identification shown in Figure 1 has been made by Chapman and Talwani (in preparation). The development of area 7 is not clearly understood at this time. Area 6 comprises Iceland and its shelf, and area 8 lies within the Norway Basin which was created by seafloor spreading early in the development of the Norwegian Sea.
