The Home of the Blizzard Being the Story of the Australasian Antarctic Expedition, 1911-1914 The hills are composed of an argillaceous schist. Successful Exploration Through the Interior of Australia Tuckey's mica slate appears to be mostly schist or gneiss: I saw only one piece of true slate which had been brought from the upper bed. Two Trips to Gorilla Land and the Cataracts of the Congo Volume 2 The sharp schist cut into his palms till they were shredded and bleeding, while his knees found every jagged bit of bed-rock over which he dragged himself. The Spoilers "Gneiss rock for eleven hundred feet and then some mica schist that we have had to shore up every time we move our drills," answered Jack quietly. Peter: a novel of which he is not the hero Relieving the grey sheen of the gneiss were dark bands of schist which tracked about in an irregular manner. The Home of the Blizzard Being the Story of the Australasian Antarctic Expedition, 1911-1914 Excavations conducted here by Schliemann in 1880-81 brought to light the broken fragments of a ceiling of greenish schist with which this lateral chamber was once covered. A History of Greek Art The steep ascent of dry, clayey soil was strewed with schist and resplendent silvery gneiss; quartz appeared in every variety, crystallized and amorphous, transparent white, opaque, dusky, and rusty. Two Trips to Gorilla Land and the Cataracts of the Congo Volume 2 It is, therefore, tolerably certain that the underlying older formation of gneisses, crystalline schists and granites, etc., is of Arch�an age, and belongs to the foundation rocks. The South Pole; an account of the Norwegian Antarctic expedition in the "Fram," 1910-12 — Volume 1 and Volume 2 The limestones have recrystallized into marbles, among them the famous marbles of Vermont; the Cambrian sandstones have become quartzites, and the Hudson shale has been changed to a schist exposed on Manhattan Island and northward. The Elements of Geology Accordingly, in the Swiss Alps, even the flysch, or upper portion of the nummulitic series, has been occasionally invaded by Plutonic rocks, and converted into crystalline schists of the hypogene class. The Student's Elements of Geology In this eastern gallery made up of lavas, schists, and coal, we have not met with a single particle of moisture. A Journey to the Interior of the Earth Examples of the third class are gneiss, slate, schist, and marble. An Introduction to Chemical Science It is seldom found in the darker coloured rocks, or in limestone country, but it sometimes occurs in gneiss, mica schist, and chlorite schist. Getting Gold: a practical treatise for prospectors, miners and students The Lower and the Upper Huronian consist in the main of old sea muds and sands and limy oozes now changed to gneisses, schists, marbles, quartzites, slates, and other metamorphic rocks. The Elements of Geology In Radnorshire there is an example of twelve bands of stratified trap, alternating with Silurian schists and flagstones, in a thickness of 350 feet. The Student's Elements of Geology The electric light was reflected in sparkling splendour from the schist, limestone, and old red sandstone of the walls. A Journey to the Interior of the Earth Importance of Siliceous Rocks.—Slate and schist are also mixed silicates. An Introduction to Chemical Science Surrounding it on all sides are micaceous schists, and in the neighbourhood about half a mile distant is a large granite hill about 800 feet high. Getting Gold: a practical treatise for prospectors, miners and students Hornblende schist is common over large areas in the Lake Superior region. The Elements of Geology Thus, in Glen Tilt, in Scotland, alternating strata of limestone and argillaceous schist come in contact with a mass of granite. The Student's Elements of Geology The marble, the schist, the limestone, and the sandstone were giving way to a dark and lustreless lining. A Journey to the Interior of the Earth But in the case of Darwin's principal geological work—that relating to the origin of the crystalline schists,—geologists were not at the time prepared to receive his revolutionary teachings. Geological Observations on South America "You would not have to look long among those fissures of slaty schist without finding peptites of considerable value." Five Weeks in a Balloon Under the resistless pressure of crustal movements almost any rocks, sandstones, shales, lavas of all kinds, granites, diorites, and gabbros may be metamorphosed into schists by crushing and shearing. The Elements of Geology Crystalline Limestone. — rocks defined. — schists, much alkali in the. — theory of cleavage. The Student's Elements of Geology Through the beds of schist, coloured with delicate shades of green, ran in winding course threads of copper and manganese, with traces of platinum and gold. A Journey to the Interior of the Earth Still more important are the conclusions at which Darwin arrived with respect to the origin of the schists and gneisses which cover so large an area in South America. Geological Observations on South America If in our days you are each confined to a standing family-dish, it is because your ancestress of the lacustrian schists never taught you variety. More Hunting Wasps The lowest member is a basal conglomerate composed of pebbles derived from the erosion of the dark crumpled schists beneath,—schists which are supposed to be Archean. The Elements of Geology They who still question this opinion may call the rocks under consideration the stratified hypogene formations or crystalline schists. The Student's Elements of Geology The temperature remained what it had been during our passage through the lava and schists. A Journey to the Interior of the Earth Let us now turn to the foliation of the metamorphic schists, a subject which has been much less attended to. Geological Observations on South America It is, therefore, tolerably certain that the underlying older formation of gneisses, crystalline schists and granites, etc., is of Archæan age, and belongs to the foundation rocks. The South Pole; an account of the Norwegian antarctic expedition in the "Fram," 1910-1912 — Volume 2 In the Black Hills the irruption of an immense mass of granite has caused or accompanied the upheaval of pre-Cambrian strata and metamorphosed them by heat and pressure into gneisses, schists, quartzites, and slates. The Elements of Geology Ribboned jasper is produced by the hardening of alternate layers of green and chocolate- coloured schist, each stripe faithfully representing the original lines of stratification. The Student's Elements of Geology Some of the shell anti schist beads were spread upon the surface of the skull, and perhaps formed a net or RESILLE, such as that already referred to as found at Baousse-Rousse. Manners and Monuments of Prehistoric Peoples In certain spots large quartz veins were numerous, and near them, the cleavage, as was the case with the foliation of the schists in the Chonos Archipelago, became extremely tortuous. Geological Observations on South America No one can travel there without becoming tiresomely familiar with fine-grained, shattered schists, coarse granites, and their curiously banded relatives, the gneisses. The Red Man's Continent: a chronicle of aboriginal America All gradations may be found between it and unfoliated quartzite on the one hand and mica schist on the other. The Elements of Geology Frequently, between the granite and the hornblende-slate above- mentioned, grains of mica and crystalline feldspar appear in the schist, so that rocks resembling gneiss and mica-schist are produced. The Student's Elements of Geology Several crucibles and moulds of mica, schist, or clay have been found with one of granite of rectangular shape bearing on each face the hollows in tended to receive the fused- metal. Manners and Monuments of Prehistoric Peoples Lower down the schist prevailed more and more, with only a few quite small points of granite projecting through. Geological Observations on South America Your expectation of the metamorphic schists sending veins into neighbouring rocks is quite new to me; but I much doubt whether you have any right to assume fluidity from almost any amount of molecular change. More Letters of Charles Darwin — Volume 2 At the two ends of the square stands two edifices, of greater height than breadth, built of a mixture of granite and schist. Colomba Fossils can rarely be detected in these schists, and they are more completely effaced in proportion to the more crystalline texture of the beds, and their vicinity to the granite. The Student's Elements of Geology On the shores of Lake Lagoda have been found some implements of argillaceous schist, in Carelia and in Finland tools made of slate and schist, often adorned with clumsy figures of men or of animals. Manners and Monuments of Prehistoric Peoples Westward of this main range, the metamorphic schists are foliated, though less plainly, in the same direction, which is likewise common to the zone of old erupted trappean rocks, forming the outermost islets. Geological Observations on South America I hope you will have a good illustration or map of the waving line of junction of the slate and schist with uniformly directed cleavage and foliation. More Letters of Charles Darwin — Volume 2 This seems to have been an upheaving agent, for the mica schists above it are much disturbed. A Popular Account of Dr. Livingstone's Expedition to the Zambesi and its tributaries And of the Discovery of Lakes Shirwa and Nyassa, 1858-1864 In some places the siliceous matter of the schist becomes a granular quartz; and when hornblende and mica are added, the altered rock loses its stratification, and passes into a kind of granite. The Student's Elements of Geology Rock of many kinds, including serpentine, schist, felsite, jadeite, diorite, and nephrite, were used; and saws of flint or chalcedony, some toothed on one side only, others on both, are of frequent occurrence. Manners and Monuments of Prehistoric Peoples About four miles from Moorahd, grey granite takes the place of the volcanic slag and schist that formed the rocks to that point. The Nile tributaries of Abyssinia, and the sword hunters of the Hamran arabs I believe even such might be converted into an ordinary varying mass of metamorphic schists. More Letters of Charles Darwin — Volume 2 Dark trappean rocks full of hornblende have in many places burst through these schists, and appear in nodules on the surface. A Popular Account of Dr. Livingstone's Expedition to the Zambesi and its tributaries And of the Discovery of Lakes Shirwa and Nyassa, 1858-1864 Foliation may be used for those alternating layers or plates of different mineralogical nature of which gneiss and other metamorphic schists are composed. The Student's Elements of Geology They ran through the wall of schist and sandstone, some shored up with great, roughly-hewn beams, others lined with a thick casing of wood. The Underground City, or, the Child of the Cavern Junction of granite and argillaceous schist in Glen Tilt. The Student's Elements of Geology The so-called beds in the metamorphic schists, so unlike common cleavage laminae, seems the best, or at least one argument against such a suspicion. More Letters of Charles Darwin — Volume 2 It sometimes gives place to quartz and reddish clay schists, much baked by heat. A Popular Account of Dr. Livingstone's Expedition to the Zambesi and its tributaries And of the Discovery of Lakes Shirwa and Nyassa, 1858-1864 In part it approaches in character to a green and blue roofing-slate, while part is extremely quartzose, the whole mass passing downward into micaceous schist. The Student's Elements of Geology "Welcome, Mr. Starr!" he exclaimed, his voice echoing under the roof of schist. The Underground City, or, the Child of the Cavern Mica and its varieties. —, how deposited. — schist or micaceous schist. The Student's Elements of Geology Hornblendic and micaceous schists are often interstratified, and beds of limestone, usually crystalline. The Student's Elements of Geology On the other side we pass over masses of porphyritic trap, in contact with the same mica schists, and these probably give to the soil the great fertility we observed. A Popular Account of Dr. Livingstone's Expedition to the Zambesi and its tributaries And of the Discovery of Lakes Shirwa and Nyassa, 1858-1864 Glen Tilt, junction of granite and schist at. The Student's Elements of Geology It had not been made in a simple embankment of stones, but in a mass of schist, which had penetrated to this depth in the coal stratum. The Underground City, or, the Child of the Cavern Sorby, Mr., on action of water in metamorphism. —, on glass cavities in quartz. —, on mechanical theory of cleavage. —, on ripple-marks in mica schist. The Student's Elements of Geology In the northern part of Scotland there occur a great series of bituminous schists and flagstones, to the fossil fish of which attention was first called by the late Hugh Miller. The Student's Elements of Geology Our course then lay down the bed of a rivulet, called Mapatizia, in which there was much calc spar, with calcareous schist, and then the Tette grey sandstone, which usually overlies coal. A Popular Account of Dr. Livingstone's Expedition to the Zambesi and its tributaries And of the Discovery of Lakes Shirwa and Nyassa, 1858-1864 Norway, Cambrian of. —, foliation of crystalline schists in. —, granite veins in gneiss of. —, granite altering fossiliferous strata in. The Student's Elements of Geology The schist was excessively hard, and it had not been necessary to bank up the end of the tunnel where the works had come to an end. The Underground City, or, the Child of the Cavern The heat, it is said, in its ascent from below, must have traversed the less altered schists before it reached a higher and more crystalline bed. The Student's Elements of Geology That the planes of foliation of the crystalline schists in Norway accord very generally with those of original stratification is a conclusion long since espoused by Keilhau. The Student's Elements of Geology In Figure 628 I have represented carefully the lamination of a coarse argillaceous schist which I examined in 1830 in the Pyrenees. The Student's Elements of Geology The arenaceous laminae are much hardened at the point of contact, and the clays are converted into siliceous schist. The Student's Elements of Geology There the vein had failed, between the schist and the tertiary sandstone. The Underground City, or, the Child of the Cavern The country where they occur is almost entirely composed of granite and different varieties of granitic schist, with here and there a few patches of Secondary strata, much dislocated, and which have suffered great denudation. The Student's Elements of Geology The occurrence here and there, in the white chalk of the south of England, of isolated pebbles of quartz and green schist has justly excited much wonder.
