"Schist" Quotes from Famous Books
 ... the strata, at first deposited apparently in water, passed into a semi-fluid state, became strangely waved and contorted, and assumed in its composition a highly crystalline character. Such is peculiarly the case with the fundamental or gneiss deposits of the period. In the overlying mica schist there is still much of contortion and disturbance; whereas the clay slate, which lies over all, gives evidence, in its more mechanical texture, and the regularity of its strata, that a gradual refrigeration of the general ...

... riding yesterday between Noble-house and Crook, on the road to this place, I fell in with a quarry of alpine limestone; it consists of four or five strata, about three feet thick, one of them single, and the rest contiguous; they all stand between the strata of slate and schist that are at the place nearly vertical. In the neighbourhood, a slate quarry is worked of a pure blue slate; several of the strata of slate near the limestone are filled with fragments of limestone scattered about like the fragments of schist in the sandstone in ...

... with a forest which yields the wood necessary for the manufacture of the charcoal, and is in the vicinity of the iron quarry, so as to reduce the expense of hauling the ore as much as possible. The neighboring rocks furnish the foundation stones and stones for the furnaces; the decomposed schist gives the cement and refractory coating, and the forest provides the wood necessary for the construction of the road, sheds, etc. The head of the trip hammer, the anvils, and the tools are the only objects that it is necessary ...

... Manhattan side was Hudson schist, while that in the reef was Fordham gneiss. Here, as elsewhere, they resembled each other closely; the gneiss was slightly the harder, but both were badly seamed and fissured. Wherever it was encountered in this work, the rock surface was covered by a deposit of boulders, gravel, ...

... a yellowish scaly product, composed of hydrated mica flakes, fills them. The mica does not everywhere present this coarsely crystalline appearance, but in flexures and lines of union with the quartz and orthoclase is degraded to a mica schist upon whose surfaces appear uranates of lime and copper (autunite and torbernite), and in which are inclosed garnet crystals of considerable size and beauty. The enormous masses of clean feldspar made partially "graphic" ...

... icebergs must have been stranded there; and that I expected erratic boulders would be detected embedded between the upheaved lava-beds; and I got Lyell to write to Hartung to ask, and now H. says my question explains what had astounded him, viz., large boulders (and some polished) of mica-schist, quartz, sandstone, etc., some embedded, and some 40 and 50 feet above the level of the sea, so that he had inferred that they had not been brought as ...

... example, in treating of the Silurian rocks of South Scotland, he says:—"When traversing the tract between Dumfries and Moffat, in 1850, it occurred to me, that the dull reddish or purple sandstone and schist to the north of the former town, which so resembled the bottom rocks of Longmynd, Llanberis, and St. David's, would prove to be of the same age;" and further on, he again insists upon the fact that these strata "are absolutely of the same composition as the bottom rocks of the Silurian region." ...

... the Lavandou upon the coast, and fancied I found the path by which St. Francis journeyed when he landed to save Provence from the plague. It is hollowed out by feet, in some places to three feet deep through the hard quartz and schist, and everywhere at least six inches, so its age is evidently great, and it must have been a path in the days of Saracen domination, if not even in or before the Roman times, for the two ...

... Leyte) from Tacloban southwards to Palos and Tanauan, two flourishing places on the east coast. Hardly half a league from the latter place, and close to the sea, a cliff of crystal lime rock rises up out of the sandy plain, which was level up to this point. It is of a greyish-green quartzose chlorite schist, from which the enterprising Father had endeavored, with a perseverance worthy of better success, to procure lime by burning. After an ample breakfast in the convent, we proceeded in the afternoon to Dagami, and, on the ...

The proportions of minerals in each of ...

... about ninety miles from the sea, the plateau is succeeded by a more level country, having detached granitic masses shooting up some 500 or 700 feet. The sandstone of the plateau has at first been hardened, then quite metamorphosed into a chocolate-coloured schist. As at Chilole hill, we have igneous rocks, apparently trap, capped with masses of beautiful white dolomite. We still ascend in altitude as we go westwards, and come upon long tracts of gneiss with hornblende. The gneiss is often striated, all the striae looking one way—sometimes north and ...

... find that the formation is igneous, prehistoric and erroneous. If I were you I would sink a prospect shaft below the vertical slide where the old red brimstone and preadamite slag cross-cut the malachite and intersect the schist. I think that would be schist about as good as anything you could do. Then send me specimens with $2 for assay and we shall ...

... and the Pallaballa range are, by some geographers, held to be identical; but I have reason to doubt this, for the specimens of rock brought home by me have been identified by the Geological Survey, those of the Pallaballa range as mica schist and quartz; those of the Sierra del Cristal as "probably schistose grit, but not definitely determinable by inspection," and "quartz rock." The quantity of mica in the sands of the Ogowe, I think, come into it from its affluents ...

... which received the name of Carystian stone, and was manufactured by the Romans into incombustible cloth for the preservation of the ashes of the dead in the process of cremation. The asbestos occurs in the same quarries with this marble, just as this mineral is usually associated with talc schist, in which chlorite and mica are often present. Strabo places the quarries of cipollino at Marmorium, a place upon the coast near Carystos; but Mr. Hawkins mentions in Walpole's Travels that he found the ancient works upon Mount Oche at a distance of three miles from the ...
