[Trasean Trafalgar]

 Note that we will only be addressing points 6 through 39 on the map, to stick within the boundaries of our own map of the boundary limits of Atlantis. All of the reference points from the map of the NCGT article make the point, however, that there is growing evidence of a great region of oceanized crust on the NCGT map. "Oceanization" refers to the conversion of continental crust into oceanic crust. And there is increasing evidence of foundering [or sinking] of the Atlantic ocean floor rocks. To give one a flavor of the types of evidence associated with the various points on the NCGT map, consider the narratives for points 6-9, which are relevant to what THC believes to be the last major portion of Atlantis to sink, Poseidia around 11,900 years before the present. Our reasons for locating Poseidia in this area can be found in our article entitled, Locations Of The Records Of The Atlantean Civilization And Its Firestone - Including Speculations On Where Or How They Will Be Found.] Full citations to referenced articles cited below can be found in the original NCGT paper.

    6    Continental rocks in Bald Mountain

    Bald Mountain, situated at 45°N latitude, 60 km west of the mid-oceanic ridge (Fig. 1), is a narrow fault block measuring 28 km from north to south, 5.5 km wide, 1.2 km deep at the top, and 1.3 km high from the ocean floor (Fig. . This seamount has remarkable characteristics in that, (a) it is oblique to the Mid-Atlantic Ridge missing cover sediment, as its name implies. The underwater camera observation revealed the exposure of massive rocks and the development of cubic joints characteristic of coarse-grained intrusives (Aumento and Loncarevic, 1969). Two dredgings on the western slope and one dredging on the eastern slope of the southern part of the seamount (Fig. 8-b; their basket drag ranges from 500 to 800 m in depth). Out of the 84 rock samples, 64 samples (75%) were continental (sandstone, limestone, gneiss, granite, granodiorite, amphibolite and granulite; Aumento and Loncarevic, 1969).

    The other 20 samples were mafic rocks – gabbro, metabasalt and basalt. Among them, coarse gabbro gave a KAr schistosity (Amento and Loncarevic, 1969). Basalts are alkaline (“transitional”), three of their samples produced K-Ar ages of 8 Ma (Aumento et al., 1968). Some basalt samples have conspicuous submarine weathering and a thick manganese crust (Aumento and Loncarevic, 1969). For the origin of granitic rocks from Bald Mountain, F. Aumento (in: Wanless et al. 1968, p. 140-141) suggested two interpretations: dropstones and continental block. However, as Aumento admits, it is difficult for the former to explain the dense distribution of continental rocks, and the latter requires a convincing mechanism to explain how the continental block has stayed at the present site without being carried away by the spreading sea floor. The continental rocks have not been registered in the Canadian Geological Survey's repository samples under the pretext that they may be glacier-origin erratic rocks, citing the lack of manganese crust, abrasion, poorly weathered features, variety of rock species and the presence of striaes at the surface (Aumento and Loncarevic, 1969). The coarse-grained gabbro was labelled dropstone, because of their belief that there are no ancient rocks near the mid-oceanic ridge (Wanless et al., 1968). However, as stated elsewhere, it is obvious that, (a) crystalline basement is exposed in Bald Mountain, (b) most of the dredged samples are continental or ancient rocks, (c) some basalt samples have conspicuous underwater weathering and thick manganese crusts (Aumento and Loncarevic, 1969), and (d) the basket drags are very long. These facts are unfavorable for Aumento and Loncarevic's claim of a glacial dropstone origin. Furthermore, as Aumento pointed out (in Wanless et al., 1968; p. 140-141), it is impossible to sustain the dropstone theory unless a reasonable explanation is given for the intensive dropping of ice-rafted rocks exclusively on Bald Mountain. In addition, the presence of continental crust in the Jan-Mayen Ridge (Fig. 2) as described earlier, and the numerous ancient continental rocks in the equatorial Atlantic axial region refute the claim of Wanless et al. (1968) that there are no ancient rocks in and around mid-oceanic ridges. The observed facts at Bald Mountain support the continental block interpretation, which is one of Aumento's ideas. The volume of the southern part of Bald Mountain is about 80 km3 (Meyerhoff et al., 1992). We expect a new survey of the region to yield a vast amount of highly valuable information on ocean-floor geology. We also call for the publication of detailed information on the dredged ancient continental rocks at Bald Mountain in regard to their localities and characteristics.
