4.2.2 Channel body 6 and 7 (Western side of Lyngefjellet)Channel body 6 shown on Figure 4.13 has a maximum thickness of 11 meters and is around210 meters wide. While Channel body 7 (Figure 4.13) is 6 meters thick and 145 meters wide.These two channels are described in the same subsection partly because they are situated inthe same area, but also because their geometry is similar. Channel body 6 is situated 29meters below Hopen member, while Channel body 7 is situated around 50 meters belowHopen member.Channel body 6 and 7 seem to have a higher portion of mud on the left side of the channelbodies, than on the right side (Figure 4.13). The colour also changes from light orange on theright side to more grey/black colour on the left side. It also seems to be finer material towardsthe top of the channel bodies (Figure 4.13). The channel bodies consist of several dippinglayers (Figure 4.13).By taking a closer look at Channel body 6, it seems like the layers at its southern most partappear to pinch out towards the overlying sandstone unit (Figure 4.13).On Channel body 7 it is difficult to see any clear indications of dipping layers towards thenorth of the channel body, while on the southern side the dipping layers are clear (Figure4.13).(1) DiscussionThe dipping layers which seem to pinch out towards the overlying sandstone unit can indicatepresence of amalgamating channel bodies, which would mean that the channel body actuallyconsists of at least two channels, where the youngest erode into the underlying channel. Thiscan contribute to an interpretation of Channel body 6, as a channel body consisting of ayounger channel with point bars and channel infill, possibly mud-plug, while the oldestchannel only displays its point bars. This indicates a multilateral channel body, which isdefined as laterally coalescent sand bodies (Potter, 1967; Gibling, 2006).Channel body 7 seems to be single-story where the dipping layers to the south are point barsand the area marked with red in Figure 4.13 is channel infill, possibly mud-plugs.52
Another explanation of the apparent fine-grained material could be that the sediments arecovered by scree and therefore have nothing to do with the sediments deposited in thatstratigraphical interval.Figure 4.13: This Figure illustrate channel bodies 6 and 7 found on the western side ofLyngefjellet.
