510 CARBONIFEROUS ROCKS IN CUMB. CO. LOGAN & FLETCHER. 



Ft. In.. 



176. Gray jointed pebbly sandstone. At the Avater level 



on the point of Sand Cove and following for some 

 distance to the southward, while still further 

 south the sandstone of 'No. 173 comes to the 

 water level 10 0- 



177. Greenish-gray conglomerate with layers of finer 



grit and of arenaceous shale 10 0' 



178. Greenish-gray and gray fine sandstone w^ith a little 



coal, seen only on the reefs. The dip now turns 

 to S. 12° W.<18°. (All the bearings in these 

 sections are magnetic). A number of small faults, 

 not well seen now obscure the section which is 

 repeated in ascending order towards the large 

 brook that flows into Sand Cove, as in Section 

 II 27 0' 



Total thickness of section 1769 4 



From the top of the 25 feet sandstone (ISTo. 173 of Section 

 I.) south along the shore at about 60 yards the dip changes to 

 S.< 50°. At 155 yards, sandstone and conglomerate dip 

 S. 20° W.< 25°. At 260 yards, a 3-inch band "of black shale 

 underlaid by fine sandstone dips S. 35° W.<33°. At 365 yards, 

 sandstone dips S. 81° W.< 31°, but seems at 475 yards to dip 

 northerly at a very high angle. There is here every indication, 

 of a fault with a downthrow to the north. The dip at one point 

 is overturned to S 1° E.<69°; the red marl, sandstone and 

 conglomerate to the northward are greatly altered, then for 17 

 yards farther the dip is w^esterly, while for the next 100 yards 

 the shore follows the strike, the dip being towards the sea. 



Few rocks are then seen to 560 yards where the dip is 

 perhaps TvT. 45° E.< 20°, beyond which for 526 yards to the- 

 mouth of Sand Brook a sand beach conceals the rocks.
