Daviankat and Rork Angfunturekh.
At Daviankat the dam is exposed fairly at tide level and is seen almost continuous along banks of stream, [illegible] or delicate as to render its feeling wholly dubious. On reaching A.T. about 450', however, the stream enters a ravine composed of thin quartz, shales etc., found to have the dip of the stream is at rather 1/8th E.S.E., 25' S.G.M. containing hard cavernous concretions, is exposed and cut by the stream. The same stratum is exposed to 1770' and the reds continue to be head of the ravine about 75' farther when they are capped by drift. The dip appears therefore to be about 500' to the mile or more, and it is doubtful whether run 200' of red beds, consisting of clean sands and dirty thinly laminated flagles etc. are exposed in this ravine. The concretions are not seen in the overlying firm formation stratum. One at about 6' long and 2' thick some farther on shows about 300' of these quartz.
At Rork Angfunturekh a magnificent exposure of this damp stream is seen. It is here probably run 400'-500' thick, and contains one or more thin bands, the thicker being about 75' (maybe 100') in thickness. The nodules are not abundant, are extremely elastic and of about one in 20 contain cores. Coral and invertebrates were discovered in nodules. Fragments of coral, apparently oolitic, are found free in both streams.
