CONTENTS. xi CHAPTER XIV. D> EXTRAVASATION OF WATER WILL NOT ACCOUNT FOR COMPRESSION. Hypothesis that oceans consist of water that has been extravasated— Density of the water before extravasation—Volume of interior which would need to have contributed it—Hypothesis shown to be inadequate to produce the entire compresston—Disturbance of crust by change of ellipticity of spherotd— Inequalities do not appear connected with suchacause. . . . 180 CHAPTER XV. COMPRESSION AND VOLCANIC ACTION. Compression not being sufficiently accounted for by contraction of the globe, alternative hypothesis that the cause of it is situated within the crust— Attraction of thickened crust not operative—Intrusive dykes may afford a key to the problem—may be widened by fluid pressure—Excess of horizontal over vertical pressure so caused—Their connection with voleante vente— Hypothesis concerning the constitution of the magma—mode of its elevation in a fissure— Pressure on the sides of the fissure—Comparison of the work of compression with that done against gravity— Mineral veins—Prof. Judd and Baron Richthofen on the relation of voleanic energy to continental movemerts— Possible additional compression upon solidification of dykes—Analogies of earth’s crust and ice—Prof. Nordenskidld’s theory of compression—Analogy of ice disturbed by skaters and earth’s crust by sedimentation—Corrugation attributed to cracks opening from below, and a continental phenomenon— Views of American Geologists as set forth by Dr Sterry Hunt—Their observed facts agree with the present theory—Effect of increased thickness of crust on compressing force—Whence the energy invoked—Circulation of rock-—Sug- gestion to explain diminished density id continental areas—‘ Red clay” of profound ocean ig. ; ‘ : ; ; , ‘ ‘ . 185 CHAPTER XVI. ON FAULTING. Faulting due to contraction—" Hade to the downthrow’’—Faults may die out in the depths—The fissure which gives rise to the fault—Fissure will have the same hade as the fault—Course of fault in a straight line—Fissures which cause faults commence at the surface—Faults of Utah described by Captain Dutton—Faulting superimposed on corrugation—Extent of throw of great faults—Faults will not usually admit the fluid magma—If they do so may give rise to fissure eruptions of igneous rock — Application of datum-level equation to faulting -— Faulting must depress the tract affected—General theoretical conclusion respecting the connection of fault- ing and corrugation . . ~ ele eee 208 COMIC OOOKS.EO
