Tuesday, June 18, 1907 2 Blackford Head West of Blackford Head from the factory extended above as a fine series of exposures of olivagite ash or breccia. These ash beds differ from those of Kenilworth & Merthyr more plainly in having a lamprophyre-granuliferous matrix of the gray or slate-gray matrix. In glass this rock assumes the character of nearly ideal green olivinite but generally the fragment included are quite serpentinous. A few specimens no 1070 were collected on the west side of the road within of the house opposite the fish factory. no 1071 is a similar fragment from the shore 100 feet east of the factory, and extends along the included gabbroic. Throughout the rock these stand out upon weathered surfaces little cubes. Of splintering neatly white or cream color. These inclusions are large fragments of dark reddish glassy olivinite or plagioclase, small globules of light gray and pink laminar matrix remnants of dark nearly black basic lava, and dark 6:51 purple fragments. Some of the fragments cover three quarters of an inch. On the west side of Broad Cave (c. 008 N of Prof Williams) occurs a little patch of gray slate striking N 25° W. Dip 2½ direction N 15° E. Shales patch of shale as a flat 11 feet square had few rock and occurs at the east end of a olivinite flow. The real locality is just above the east cornering place the latter 5th, and on the west end of this little cave. The forest in three little patches include good numbers of ostracodes (Oysterella, ? Ophrimella, a few Cypricardate? (one specimen them 2 or 3 cardinal teeth), a few Mytilus = Crustacea? On the east side patch of shale is where it appears to be olivinite flow. Between the flow & the shale there is very dark slate like rock 1072 of the longest of which lava N. 10° E, out of the upper part is suddenly deflected into vertical and leans along NW. Here appear and contain large quartz non crystals dolomitic shale = 043. It appears to be intrusive into the olivinite or gabbroic olivinite with "fine lines" appears on both sides of it, up to the blade on the east, & extending westward. Wherever cliff is composed of a purple olivinite rock which exhibits horizontal flow lines and a weak subcolumnar structure. These flow lines stand out on weathered surfaces. A few specimens 1073 show than quartz well. The matrix is glassy & nearly dark purple, becoming pinker at spots one hundred & fifty feet the west the lava gradually turns gray or greenish and in such is quite gray. At a little point there occurs some ash & possibly flow breccia. A specimen was collect ed at 1075 showing the gray-green matrix. no 1041 B is a specimen from the hill north of the highway in west central 6:5: V. It shows the lavender purpleish inclusions & jellies. 2d rock composes this hill. Wednesday, June 19, 1907. as the head of Deep Cave, on the south side (opposite to) 3 mining work & then one foot like gabbroic rock, c 676 projects up into the olivinite without great cutting through. its olivinite continues in beautifully swept and covered sea cliffs (caverns underneath as those of joint planes) for about 100 yards eastward, where the pink olivinite is succeeded by a gray volcanic brecciated on faces of lava are sometimes black, occasionally dark brown. A few weathered amygdaloid stone in places in other rocks blend is 1077. These rock appears clearly the pink olivinite but the appearance so indicated in its figures may be due to recent erosion. The olivinite laden a roofs seen in the west above A (olivinite), and on the north side B (gray rocks) from antiquity of 1077 rock. The rock composing 1077 shows low ledges on east end, with the huge cliffs of olivinite rock. Figure 2 represents a little section in the westward of detached cave in the middle of the cliff gorge facing the model. 6:4:9 a" is the lower side on the south edge and represents a gabbroic 1075 olivinite very coarse N 250° W dip 45 on average of 40° take N. 60 E. "B" is a larger dark purple flow with almost sharply similar strike and dip. Weathered border lava is about 11 feet thick. (c) B is succeeded by some rocks 13 feet thick which at a distance resemble somewhat light gray colored shale, but when examined more closely are seen to be very finely ground left ejecta traces of a very light gray color with dark green spots and not angular inclusions of pink olivinite the latter 14 to ¾ inch thick nearly on inch thick. C is followed by some level beds. D strikes vary from 0-15 feet within a distance of 50 feet NW. Under the rock as with ash-like bed which is distinctly crowned on the upper part. E. The top of the section is formed by an exceedingly interesting masses of ash tides. The matrix is a very fine dark purple glass similar to many of the best fragments of dark purple olivinite in the Perry. Included in this mass of dark purple magma there stand out light gray colored spots which when examined are seen to be common glass Silicium chales. These shale inclusions are generally 1 to 3 inches thick; some of less rounded rarely a fragment 6 inches to a foot thick. Besides the typical light gray shaly bits which are included in fragments there are also included red and gray nodules that led figures similar to those occurring in 24:7. These final red fragments are some of them nearly a foot thick on.
