Gneiss   Listen
noun
Gneiss  n.  (Geol.) A crystalline rock, consisting, like granite, of quartz, feldspar, and mica, but having these materials, especially the mica, arranged in planes, so that it breaks rather easily into coarse slabs or flags. Hornblende sometimes takes the place of the mica, and it is then called hornblendic gneiss or syenitic gneiss. Similar varieties of related rocks are also called gneiss.

"Gneiss" Quotes from Famous Books



... goes a wealth of color. Never, I venture to say, were reds and browns and grays and vermilions more appealing to the eye than they are as they softly glow in this great canyon. The color-scheme runs from the dark, sombre hue of the gneiss at the bottom, up through the yellowish brown of the Cambrian layers, and on up through seven or eight broad bands of varying tints of red and vermilion, to the broad yellowish-gray at ...

... islets. On the north bank are many of the crater-like sinks which dot the coast from the Gaboon to Loango. We hugged the right side to avoid the rapid swirl; there was no backwater at the points, and hard work was required to prevent our being swept against the boulders of gneiss, schiste, and pudding-stone edging the shores and stretching into the stream. Here the fish is excellent as at Porto cla Lenha, and we found the people catching it in large spoon-shaped basins: I enquired about the Peixe ...

... on a few ingredients in this magnificent pharmacy; its resources are boundless, but require the nicest discretion. I remember to have cured a disconsolate widower, who obstinately refused every other medicament, by a strict course of geology. I dipped him deep into gneiss and mica schist. Amidst the first strata I suffered the watery action to expend itself upon cooling, crystallized masses; and by the time I had got him into the tertiary period, amongst the transition chalks ...

... began with simple words in common use, like a-b ab, and e-b eb, and i-b, ib, proceeding by gradual, if not by easy stages to honorificatudinibility and disproportionableness, with a department at the back devoted to twisters like phthisic, and mullein-stalk, and diphtheria, and gneiss. We used to have a fine old sport on Friday afternoons, called "choose-up-and-spell-down." I don't know if you ever played it. It was a survival, pure and simple, from the Old Red School-house. There was where it really lived. There was where it flourished as a gladiatorial spectacle. ...

... greater part of the globe, subterraneous fires have pierced through the rocks of primitive formation. In treating hereafter of the great number of warm springs which we have seen issuing from granite, gneiss, and micaceous schist, we shall have occasion to return to this subject, which is one of the most important of the physical history ...

Cannot we do what we like with our own?—Yes, indeed! For my share, if I could melt Gneiss Rock, and create Law of Gravitation; if I could stride out to the Doggerbank, some morning, and striking down my trident there into the mud-waves, say, "Be land, be fields, meadows, mountains and fresh-rolling streams!" by Heaven, ...

... For the rest, of any good or evil extent, it is impossible to say what measure is owing to restraint, and what to license where the right is balanced between them. I was not a little provoked one day, a summer or two since, in Scotland, because the Duke of Athol hindered me from examining the gneiss and slate junctions in Glen Tilt, at the hour convenient to me; but I saw them at last, and in quietness; and to the very restriction that annoyed me, owed, probably, the fact of their being in existence, instead of being blasted away by a mob-company; ...

... so changed that we cannot any longer make sure that any animals lived in them, are called the "archaean," which is Greek for ancient. They were probably mud and sand and limestone when first made, but they have been changed to mica schists, gneiss, granite, marble, and other crystalline rocks. When any rock becomes crystalline, the fossils dissolve and disappear, as coins lose their stamp and form when they are ...

... place he had to build barracks for his workmen on the Isles of Tyree and Mull, and then to begin the foundation of the tower on the only one of the gneiss rocks of the reef which was broad enough for the purpose, and this is but barely so, for at high water little remains around the tower's base but a narrow band of a few feet of rugged rocks, washed into gullies by the sea, which plays through them ...

... of the extensive site occupied by the ruins of Bijanugger on the south bank of the Tumbuddra, and of its suburb Annegundi on the northern bank, is occupied by great bare piles and bosses of granite and granitoidal gneiss, separated by rocky defiles and narrow rugged valleys encumbered by precipitated masses of rock. Some of the larger flat-bottomed valleys are irrigated by aqueducts from the river.... The peaks, tors, and logging-stones of Bijanugger ...

... its wild cliffs and caverns. The Hill of Cromarty is one of a chain belonging to the great Ben Nevis line of elevation; and, though it occurs in a sandstone district, is itself a huge primary mass, upheaved of old from the abyss, and composed chiefly of granitic gneiss and a red splintery horn-stone. It contains also numerous veins and beds of hornblend rock and chlorite-schist, and of a peculiar-looking granite, of which the quartz is white as milk, and the feldspar red as blood. When still wet by the receding tide, these ...

... eat out hollows in the plains below; and now in those hollows were lonely lakes, with not a tree to break the line of their melancholy shores. Everywhere around were the traces of the glacier-drift—great gray boulders of gneiss fixed fast into the black peat-moss or set amid the browns and greens of the heather. The only sound to be heard in this wilderness of rock and morass was the rushing of various streams, rain-swollen ...

... The first step in the change was the cracking of the quartz and feldspar crystals and development of muscovite and chlorite in the cracks. This was accompanied by a growth of muscovite and quartz in the unbroken feldspar. The aspect of the rock at this stage is that of a gneiss with rather indefinite banding. Further action reduced the rock to a collection of angular and rounded fragments of granite, quartz, and feldspar in a matrix of quartz and mica, the mica lapping around the fragments and ...

... him from incurring her contempt for collectors; but he knew by sight the character of the conformations of rocks, and when they had mounted one of the hills that surrounded Avonmouth, discerned by the outline whether granite, gneiss, limestone, or slate formed the grander height beyond, thus leading to schemes of more distant rides to verify the conjectures, which Rachel accepted with the less argument, because sententious dogmatism was not always possible on the back of ...

... may be formed of the nature of these incurvations by supposing the gneiss beds to have been in a plastic state, either from the action of heat or of some other unknown cause, and, while in this state, to have been subjected to pressure at the two extremities, or in some other parts, according to the nature of the curvatures. But even this hypothesis (though the best that ...

... obtained from a fixed position, enabled us to locate the peak. The bearing of the Trois Tetons was north 50 degrees west, and the direction of the central ridge of the Wind River Mountains south 39 degrees east. The summit rock was gneiss. Sienite and feldspar succeeded in our descent to the snow line, where we found a felspathic granite. I had remarked that the noise produced by the explosion of our pistols had the usual degree of loudness, ...

... Monte Video; but as there was a strict quarantine, Agassiz was only allowed to land at the Mount, a hill on the western side of the bay, the geology of which he was anxious to examine. He found true erratics—loose pebbles, granite, gneiss, and granitic sandstone, having no resemblance to any native rock in the vicinity—scattered over the whole surface of the hill to its very summit. The hill itself had also the character of the "roches moutonnees" modeled by ice in the northern hemisphere. As these were the most ...

Besides, the limit of trees has a quite dissimilar appearance in Siberia and Scandinavia: in the latter country, the farthest outposts of the forests towards the north consist of scraggy birches, which, notwithstanding their stunted stems, clothe the mountain sides ...

Others had no known type nearer than Connecticut, in the opposite direction, while the gneiss and mica slate of the island of New-York, with their various embedded minerals, the serpentine and many of the magnesian minerals of Hoboken, with sandstone and trap of the Pallisadoc range, were distinctly recognisable. In this great excavation, where a region of a mile square was wholly removed, ...

... ocean.[80] He goes so far as to assert that the porphyritic rocks were not thus formed in the sea, but that they are the result of deposits carried down by streams, especially torrents flowing down from mountains. Gneiss, he thinks, resulted from the detritus of granitic rocks, by means of an inappreciable cement, and formed in a way analogous to ...
