The rock has been subjected to strong shearing force, producing a good example of schistose structure. 12 Quartzite Same location as No. 9. A compact rock of light red color, made up of uniformly rounded grains of quartz, and the feldspar with occasional grain of magnetite. A fine siliceous material discolored by iron oxide, acts as a cement between the grains.
It is a spot whence lovers might easily step into eternity, were they so disposed, and the name fits delightfully into the wild and somber scene; but ask any good villager thereabout to relate the legend of the place and he will tell you this: About forty years ago a couple of young farmers went to the Leap which then had no name to pry out some blocks of the schistose rock for a foundation wall.
In regard to the age of the gold of the Ural mountains, in Russia, which, like that of California, is obtained chiefly from auriferous alluvium, it occurs in veins of quartz in the schistose and granitic rocks of that chain, and is supposed by Sir R. Murchison, MM. Deverneuil and Keyserling to be newer than the syenitic granite of the Ural perhaps of tertiary date.
A. Canaan range, in the State of New York. The crest consists of green chloritic rock. B. Richmond range, the western division of which consists in Merriman's Mount of the same green rock as A, but in a more schistose form, while the eastern division is composed of slaty limestone. C. The Lenox range, consisting in part of mica-schist, and in some districts of crystalline limestone. d.
The shale, as it approaches the trap, becomes gradually more compact, and is most indurated where nearest the junction. Here it loses part of its schistose structure, but the separation into parallel layers is still discernible. In several places the shale is converted into hard porcelanous jasper.
There are liquid clays, springs, hard rocks, and those soft and deep quagmires which special science calls moutardes. The pick advances laboriously through the calcareous layers alternating with very slender threads of clay, and schistose beds in plates incrusted with oyster-shells, the contemporaries of the pre-Adamite oceans.
They were thickly covered with eucalypti and brush, and, though based upon sandstone, were themselves of a schistose formation. Yharr or Yass Plains were discovered by Mr. Hovel, and Mr. Hume, the companion of my journey down the Macquarie, in 1828. They take their name from the little river that flows along their north and north-west boundaries.
The clay, which renders the soil so slippery, is produced by the numerous layers of sandstone and schistose clay crossing the bluish grey alpine limestone. This last disappears as we draw nearer to Cariaco.
Kent remarks that it superseded the schistose formation at the ravine we have noticed and that, subsequently, the sides of the hills became more broken, and valleys, or gullies, more properly speaking, very numerous. Captain Barker estimated the height of Mount Lofty above the sea at 2,400 feet, and the distance of its summit from the coast at eleven miles. Mr.
