36 RHYOLITE TUFTS BASIC TUFTS GABRO SHALE RHYOLITE DIKE Trap dike RHYOLITE FLOW Horan head Black Head The core at the south end of H. 120' W. on the west flank of Black Head contains in the overburden with it, the face of Black Head some stratified tuffs striking approximately N. 30° W. and dipping at an angle of 45° to 70° N. E. At the easternmost branch of the core occurs a 152-foot trap sill striking N. 20° W. on the west side of this easternmost arm; some coarse stratified basal gray tuffs similar to, but significantly less granular, red on the end of Danby Point. Ole strike at N. 45° W. dip 50° N. E. On the west side of the point the tuffs are on the south pattern. The limit the greenish flow are irregular; strike N. 70° W. dip 60° and nearly some coarse fegry tuff. These massive fragments contain ell & simple chlorite porphyry, flake rhyolite etc. embedded in a dark gray stratified matrix. A boulder of black gray shale at this point contains a few layers that are not on face but the second little one is the west of Black Head; some platy blue slate may be on the west side merging some tuffs which form the foreplaner top of the point. The shale strike N. 35° W. the strike being about to N. 50° W. at the top of the point. It dips at 36° N.E. The lower 10 feet of shale contains a rare Murchisonia (?): Hyrichia = 6:92:4 A. West of the I had seen, going up I on the north shore black slate about 25 feet in exposure and dipping at 80° to 70° to the N. N.W. or N. 49° W., dip 25° N.E. The strata cut by gallo. In the Allen arm N.W. 642:9 M.N.W. of the foot surrounding area near that labeled behind in gray tuffs dust layers striking N.W. and E.S.E. 30° N.E. all at a dip of 50° to 70° N.W. On the other side with this last part is not clear, but I think black in S. The strata are not exposed; the bottom in central Allen arm. Murchisonia found and studied the same species as seen in the Holcomb Cove outcrop (see p.). The fauna in 6:92:9? Just present is a gray tuff that is the same as the one above, but I believe it is a different one. Harriet Head shore on the east side of Allen arm; a sample taken at label behind 5 to 10 feet thick which we call 1 upon the gallery and strike N. 53° W. dip 45° N.E. The shale on this side of lake is also very light, and still in effect near H. Bay or Bella Lake and permit some more. I have 17 from one locality at others. A newer core in the north end of Allen arm; a gray stratum followed by a series of massive tectonic granite body N. 54° W. (dip 45° N.E.) right into older slate, strike N. 20° W. dip 75°. Field of three slabs are exposed at this locality near the lake between 6:92 & the one contain only are specimen to large spacing of mineral. (1) 3:27 A The top is 30 feet of sand, some very slight gray tuff formed upon it; and under the gallery I find under slate of mud and coal. It is a foot.
