"Igneous" Quotes from Famous Books
 ... concerning the primary causes of volcanoes, and many explanations relating to the igneous matter discharged from their craters. Like the doctors who disagree in the diagnosis of a human malady, the geologists and volcanists are equally unable to agree in all details concerning this form of the earth's ailment. After all theories ...

... most of these hills, as of many all over the plateau, is that they are flat-topped, and have often steep, even craggy escarpments. This seems due to the fact that the strata (chiefly sandstone) are horizontal; and very often a bed of hard igneous rock, some, kind of trap or greenstone, or porphyry, protects the summit of the hill from the disintegrating influences of the weather. It is a bare land, with very little wood, and that small and scrubby, but is well covered with herbage, affording excellent pasture during two-thirds ...

... themselves in America,—then, more briefly, as they appear in Europe. A full account of the life that manifested itself in each epoch, both vegetable and animal, is likewise given in the same order. The igneous and other disturbing agencies are then considered, and general remarks added upon the geography, the character of the surface, and various ...

... wider than above, and we could see the summits around that were six thousand feet above the river, but some miles back. In the morning I made a geological sketch, and in the afternoon I climbed a high peak and put in some of the topography. The next morning we crossed the river to examine a large igneous butte where we found a small vein of copper ore, and after dinner Prof. and I climbed a couple of peaks and did some triangulating. Monday the 26th found us still at Camp 94 to further investigate the surroundings, and the Major, Prof., Jones, and I climbed up on the north about 2600 feet in ...

... the centre of the great crater of Epomeo..., and therefore lies immediately over the ancient chimney, which in all probability is filled by an old plug of consolidated trachyte, which must descend to the igneous reservoir. Any mass of igneous matter, that might determine the further rupture of a collateral fissure, would result in the conduction of any changes of pressure or vibrations, along the column of highly elastic trachyte; whilst the same earth-waves ...

... larger numbers than in any other locality. Kashmir, in India, also supplies splendid specimens of large size. Ceylon, too, furnishes a good deal of sapphire, but mostly of a lighter color than the Kashmir sapphire. The Ceylon sapphires are found in the streams, but originate in rock of igneous origin. ...

... strata, was the infant condition of the earth. Points of unconformableness in the overlying aqueous rocks, connected with protrusions of granites, and other similar presentments of the internal igneous mass, such as trap and basalt, mark the conclusions of subsequent sections in this grand tale. Dates, such as chronologists never dreamed of—compared with which, those of Egypt's dynasties are as the latter to a child's reckoning of its birthdays—have thus been presented to the now living ...

... as well as their magnetic properties. The attributes of a practical mineralogist aided him greatly in the culture of a branch of geology to which Delesse has rendered eminent services, in the recognition of rocks of igneous origin and of others allied to them. He studied in the field, as well as by investigations in the laboratory, for fifteen years, with an intelligent and indefatigable perseverance, and, aided by the results ...

... little doubt that in this underlying floor of igneous and metamorphic rocks we have reached those surface materials of the earth which existed before the long epoch of sedimentation began, and before the seas came into being. They formed the floor of a vaporised ocean upon which the waters condensed here and there from ...

... a rule, the kopje of the veld is a lonely hill, a mass of igneous rock—flat-topped or sharp-pointed. From 200 to 800 feet in height, without spur or underfeature, accessible only by winding paths among gigantic boulders, sheer of face and narrow of crest, it is more useful as a post of observation than as a natural fortress; for it can almost always ...

... through Guienne into the Gironde. The high and bare mountain whence the Dor derives its principal source is the Pic de Sancy, the loftiest hill in the middle of France; it is the king of all the volcanoes of this vast igneous chain, and has its sides deeply furrowed and excavated into immense craters or volcanic vents. From it proceed numerous branches or arms, composed of basaltic currents congealed into columnar masses in the early days of the world. ...
