July 20-1918 Bennits Brook. To the north of the trap appear odales that as a rule are gneissic, often overthrown main horn and green gneissic odales. Only once did we see Haach odale, interwoven with thin beds (4 to 6 in) of fine grained sandstone. These odales continued for at least 1/2 miles north. Their structure is exceedingly complicated by warping and faulting so that one cannot make out the thickness, even guess at it. However there appears to be an overrolled repetition of the beds. The odales then give way to finer grained arkosic sandstones that become more and more coarse grained toward the north. Finally the pebbles attain the size of peas. The cryllostrates in proportion are increased, and the bedding is irregular almost like that of continental deposits that one appears to be of marine origin. The amount of red feldspar is striking, though far less quantity than the quartz particles. In the various samples. There can be no doubt that the basalts are flows and not dykes erupted quickly. We have however no data as to when these flows took place. Their structure is against the idea that they are intrusives.
