Federal Harbor 6/1-8/642. blue = shale C [illegible] and tuff [illegible]

Federal Harbor On the south side of Federal Harbor near the west end, along the shore on both sides of the outlet of Mr. Dickey's lagoon in northern G.V.I.A and just over the lake into G.V.I.5 a lens seems of gray sand tuff, fine grained & chervely last well obliterated, immediately the Silvers Cove glassies. The strikes along the shore from N.25-27° W. and dip 35-42° N.E. The tuffs are very fine siliceous containing many small shells of siliceous remains. Specimens of Eucyathina decua is very common. the remains of large Porifera sp, Lymella cunabula occur as a trace of 664 "Opisthobranch tuffs" of Silvers Cove & forming tube. The fauna in G.V.I.5 A and includes Camarotoechia abundant Gonorettes derjysi, common Cyclocoma aluandant Actinoptercella rare Palmappeila rare Pyrophisonia rare Naryschonia rare Terraculites rare Crinoid ?? common The specimens of the brachiopods distributed with the Camalitocheica gastropods which seem to occur in Silvers Cove, interestingly enough at a depth a few yards below of Mr. Dickey's where the Peglet's tuffs, are and by a very dark lens 25 ft. thick which appears to be a stratigraphic on a large galbino near the galbino which parallels the shore on a little point west of the W. end. 6/41.5 Just to the east part of this galbinos gneiss in the S.E corner of the SW quarter of G.V.I.5 occurs in the west a couple of yards of slightly bluish tuffs overlain by gray bluish-gray olivite beds, N.12° W and dipping 35° N.E.. The strata here occur several feet thick & very well developed. the fauna is ? ? (gray water) with small shells & calcareous mass & dark forming the 60 foot sill W of S of the latter F in Federal Harbor. Intercalated in the mass of galbino ruff 36 feet long beds sandy shales striking N.25°W and dipping w.s.e. These occur on the west side of this point S.W. of the 800 F in Federal Harbor, and contain (G.V.I.516) Orbiculidae ? camarotoechia common Palmappeila (Eucyathina sp.) abundant Actinoptercella uncommon Cypicardium platyphylla one example Pyrophisonia rare Cyclonoma Black Head 23 the base of Black Head on the west side seems coarse gray bedded tuffs striking N.35° W and dipping N.70° S.E. The top they become fassation and grade up into effect of white thick gray pulverized slates which lie in turn northern by a couple of feet of tuffifer, these places the slates. The loose lichen covered tuffs immediately underlying contain & red faunas with gings 6V25 Camarotoechia (Eup) abundant Gonorettes derjysi common Palmappeila rare Actinoptercella rare Cyclocoma (P. Siliceous core) abundant. Pyrophisonia rare Cylonea common Balanusites magnoval Actinoptercella Just beneath the galbino the strike is N.47° W and dip 45° N.E. North of the forest occurs on the lower side of Black Head the tuffs disappear some striking W. 30° W. and dipping 50° NE. They are dark gray & red, and under 2125° and much layered & grey the latter extremely amygdaloidal or pyroclastic. The beds and coarse plates of G.V.I.A (N.3 P) is exposed in old road side of Federal Hare Peglet's rock struck but I believe core copy of these shots as probably probable the thick 2

may be fifty feet - or upper few feet exposed location? A rare fossil horizon for Gastropod shells 6.41.8 (last) Perhaps 25 feet above the point with mud on the north side of the point -- a rare event occurs on the east side. 1/0 inches of very dark gray shale - also - was typical for the upper few miles, area -- was a layer of clay and sand? [illegible] Proceeding southward from the point, Fading harder -- use of mud -- is typical of our locality. The fossils in this area of tuff, include: Clypeus Camarotoechia, ? Dalmanella et al., the same as 6.41.8 A. North of the creek there begins a trap mass which follows the shore line - for a couple of hundred yards southward - as far as the clay point. Two text patches of shale's one of blight fringe the trap along part of the shore. The contact is a way fault Trending in general N 30° W., but whether the fault is due to intrusion of the trap or to subsequent slipping appears indeterminate. The northmost patch of shale so - is just south of the creek and extends for about 50 feet along the shore, about 10 feet of splintery blue shales crop out in front of the trap in going down. The strike is N 32° W dip 40° N.E. at the south end and the strike curves around to N.12° E., dip 37° E. at the north end. Only Actinoptrella was placed in the shale = 6.41.8 C, rare. On the north side of the clay point (the con- spicuous projection halfway down the east side of the west end of Federal Harbor occurs a thick [illegible] 25 ft or more) gabbro dike trending N 30° W. It is the only exposure in the point. Perhaps 50 or 75 - feet S. of the clay point is a series of exposures beginning in the north with a few feet of marine tuff of a gray color = 12.59. These are cut off on the west by a 10 ft. trap dike trending N 20° W. apparently toward the gabbro on the N side of Clay point. To the west of the trap dike are some gray tuff- like tuffs, the bedding planes of which have been disturbed so that it is impossible to ascertain the strike & dip. A few fossils were collected here = 6.41.8 D Orbiculoidea, ?Camarotoechia R., Dalmanella (Selby) or Core) common, Actinopterella occasional, Orthoceras ludense R. A hundred feet or so to the south are some very coarse grained tuff, having the appearance of nearly crystalline acid volcanoe. The strike is N 54° W., dip 46° N.E. D specimen is 12.60. This tuff underlies a few feet of fossiliferous tuffs which are less than 50 feet away running from strike N 37° W dip 35° N.E. to strike N 54° W dip 46° N.E. The fossils here are 6.41.8 E (not collected) including Dalmanella (Selby - Core) common Camarotoechia sp Cypricardinum "platyphyllum" occasional Orthoceras ludense rare South of this point for about 100 yards or less the rock is a fragmental massive tuff, the fragments are darkish gray in a similarly colored matrix. Specimen 12.61. A couple of feet of more a yellowish tuffs appear to indicate an oxidation depos about 50 yards north of the south end of Federal Harbor and contains Dalmanella = 6.41.8 F. A few yards north of the south end of Fed- eral Harbor occur a few feet of "granular tuffs" gray acid changed with feldspar plagioclase, at the extreme south end of Federal Harbor the rock tumbles over some distinctly reddish and fine grained tuffs - striking N 30° W and dipping 34° N.E. On the fields southeast of Mr. Roberts' farmhouse occur some outcrops of new tuffs with occasional gashes of a few inches to a couple of feet of splintery gray shales, these cut & gabro dikes. A couple of feet of gray shale occurring east of the road near the mid-baghet of the S.E. quarter of 6.41.8 contains a few Cypricardinum "platyphyllum" = 6.41.8 B.

{ "text": "Southwest of the house of Mr. # there occurs on the west side of Devils Neck and on the east side of Morrison Cove a strip of dark blue thinly bedded shales. Almost 30 feet of shales are here exposed striking N. 40° W. and dipping 45° N.

These fragments are also found on the shale line for a couple of hundred yards when there appears on the shore due west of Mr. # house an other patch of thin evenly bedded dark blue shales. About 25 feet of shales which are similar lithologically to 5.35.5 A seem here striking N. 50° W. and dipping 45° N. E.\n\nThey are again cut off on the west by a thick coarse grained gabbro. Near the contact the shales are deflected striking N. 75° W. and dipping N. 32°.\n\nThe dark blue shales as here exposed are about 20 feet thick and the gradation into the overlying fragmental tuff may be observed on the south end of the exposure.

These are followed by a gulfish trappean rock which in the upper part is succeeding amygdaloidal and quenadious. The upper surface of this purpureous extrusion is irregular and celibate hummocks' base 5-6 feet broad and 1 or 2 feet deep. The rock is immediately overlaid by coarse thick bedded blue shales striking N. 53° W. About half way down the cove these shales are offset about 50 or 75 feet to the S.W. by a fault striking N. 30° E. 2-1/2 to 6 feet above this point the shales contain calcareous nodules or concretions. A few of these calcareous masses appear to be of coral nature and a few specimens were pieces of simple large corals but too poorly preserved to warrant the labor of extracting the specimens.

8 cove and the strike may be seen to swing around to N 53° W, in an even curve. These dark blue shales underly cliff 50° N E, and underly an exposure of about 20 feet of very light gray tuffea composed of rhyolitic material and apparently the same as depose occurring on the northwest side of Horan Head. (As much and of the zone there is another fault bringing the same tuffea eastward along rift or more.) A trip was made to the east end of Horan Head to determine the nature of the rhyolite on the south side - whether intruded into the gabbro or the gabbro intruded into the rhyolite. The rhyolite here about 60 feet broad. The gabbro is coarse grained and uniform up to within 2 to 4 weeks of the contact this 2 to 4 foot irregular band is slightly demarcated from the rhyolite on the west end; the gabbro on the east. A specimen as 1262, is a dark fine grained rock but not quite so glassy as in usual for rhyolite. The rhyolite 1 foot from the contact is dark blue & glassy: 1263 25 feet from the contact the rhyolite lighter tblue or almost gray 1264. One foot further in the rhyolitic tuffea becomes grayish & coarser, and 10 pit still farther in the rhyolite, 1266 becomes pinkish. In this one foot land there are included rounded mattered fragments of a much darker apparently basic rock though fine grained. A specimen of the rhyolite with one of these fragments is 1263 B About a quarter of a mile due west of the north end of Federal Harbor there occur in the delta about 100 feet west of the highway a series of light redish gray blue acid tuffea and greenish grey sandstone beside the latter resembling those of Old Long Cove beds. The strata strike N 74° W, and dip approximately 35° N E. Several seams 1 inch to five inches thick in the tuffea are full of finely preserved casts which yield a rich fauna. S 641-7 A (the faunas also crop out above the boundary between 641-7 and 651-9. The fauna is exceedingly rich both in brachopoda & mollusca including camarotoechia (of Long Cove) abundant Chonetes denysi, abundant Dalmanella [Schonera? species] common Grammysia angulata var. occasional Actinoptercella 2 or 3 spp. common Pteronitella retroflexa occasional Goniophora 2 spp. (one of them G. rhomber type) Mollopso? platyphyllis occasional Ctenodonta 2 spp. occasional various lamellibranchs common Murchisonia 2 or 3 spp. common Cornulites rare Dalmanites for R Calymene for R 9 Perry asswity 6 N - Below the railroad, between the highway and creek over Little River, and just west of a wire fence there near on the north bank of Little River, see locality 38.
