As mentioned in subsection 4.2.5, Channel body 10 is found on both sides of the island. Onthe western side of the island the top of channel body 10 was calculated to be 130 meters fromthe base of Hopen member. The distance from top of what is interpreted as Channel body 11to the top of Channel body 10 on the eastern side, is about 70 meters. Assuming the samedistances from top of Channel body 10 and base of Hopen member on the eastern side,Channel body 11 is situated approximately 200 meters below the Hopen member. That meansthat channel body 11 is the lowermost channel body described4.2.7 Channel body 12 (Western side of Kollerfjellet)The overview photo (Figure 4.22A and B) referred to in this subsection is displayed insubsection 4.2.5, Channel body 10, as both of these channel bodies are situated in the samearea.Channel body 12 is situated approximately 42 meters above sea level on the western side ofKollerfjellet. On the eastern side of the mountain the channel body is not found. The top ofChannel body 12 is situated about 179 meters below Hopen member. The channel body isfound to be about 20 meters thick, but the width is difficult to estimate as the pinch out to theNE is disturbed by a displacing fault (Figure 4.22). However, assuming that the greysandstone unit sticking out at sea level (Figure 4.22) represents the same channel body, thewidth is estimated to be approximately 917 meters. Channel body 12 is displaced by twofaults. The fault furthest to the south displaces the channel body with about 11 meters, whilethe other one (further to the north in Figure 4.22) has a displacement of about 40 meters. Thedisplacement of the northern fault assumes that the grey sandstone unit sticking out at sealevel is part of the channel body. On this channel body one can see a pinch out (Figure 4.25)towards the SW. The channel body is covered by a lot of vegetation, making it difficult tointerpret the internal geometry of the channel body.(1) DiscussionAs described in subsection 4.2.6, Channel body 12 on the western side is most likely not thesame as Channel body 11 on the eastern side of the island. Never the less this channel bodyshould have been possible to see on one of the logged section on the eastern side of themountain (Hopen radio nord and Gåsskaret in Appendix 1) if channel bodies 10 and 12 hadmore or less the same direction. Unfortunately it is not possible to see any channel body70
indications on the logs from the stratigraphical interval of Channel body 12. This can either beexplained by missing logs from this interval, or that the channel is situated where we todayfind Hopen meteorological station and is eroded away by the same mechanisms as thesouthern pinch out of Channel body 10 (Subsection 4.2.5). The latter can be the case ifChannel body 12 has a NNV-SSE direction, which is not unlikely. If the channel body issituated between the Hopen radio log and the log taken at Gåsskaret, it should have beenpossible to see it on the photos.The distance from Hopen member indicates that the channel body is deposited as one of theoldest channel bodies on the island.Figure 4.25: Illustration of the southern pinch out on Channel body 12.
