I lose limestone strike toward and appear to pass under the horizontal
shelves of the south end of Blackford
Island. Its limestone contains in places
many ostracods - one or two specimens
collected = 6.24.9a.
The little ridge on the boundary to
west 6.24.5 & 7 is a gray dike of a fluffy
gray rock which is amorphous and
(Porphyritic) in rare spots. This
dike 1886 bears N. 20° W. Newark
Dip 36° NE.
The ridge immediately west of this
is composed of pumice concretions
limestone with holes at the top. The
concretion bands are modular and end up
by thick massive shrinkage cracks which
have been filled in with gray calcareous mud
dams of the beds are mostly masses of
concretions 1 to 2 inches thick. The
rock is the gray limestone crystalline
in places but generally fine grained
and containing ostracods scattered through
and % or so fairly clustered within
with an occasional Zygurita = 3.24.Pa.
The limestone bands are 1 to 3 inches thick
with fettings of thin shale, generally
half an inch thick or less. 18 feet of close
concretionary limestone ends and are
followed by 4 feet of thin fine-grained
in 1 to 3 foot masses with 1/2" to 2" cal-
careous seams. Its shale relief is quite
clearly a cleavage or rather fragmentation
anterior to that of 6.29.Pa.

The rocks strike due west and
dip 22° to the east.
The principal joint in central 6.24.P
shown on this map is a series of lime-
stones which are cut at the surface by
a thick 10 foot gabbro dike "dike A"
is massive rock unders level under
the limestone & appears to be the top
edge of a high steep dome. This dike ex-tends N.30° E following along the tops of the
argine limestones are seen to strike N
10-15° west & passing north-westernly
along the cape the line of strike trends
around toward the mid side of
Cooper Island or N 45° W. The dip is
steward 20°, or from east to north-
east. About 40 feet of these limestones
are exposed on the east side of the point
and containing ostracods (Argyriosa)
with a rare Zygurita & very rare trigula
= 6.24.Pa. This forms at about 50 feet
stratigraphically below 6.24.Bd. The
beds of 6.24.Bd - Bd underlie in the
former about 40 feet of limestone,
top of about 30 feet and then 1 foot
of 6.24.Pa or a total of 90 feet of sediments
(limestones, including the creek gap).
