204 COMPRESSION AND VOLCANIC ACTION. [cu. xv. violent mountain-forming movements occurred, these fissures were in their most active condition, and at this time two great volcanic belts stretched east and west, on either side of, and parallel to, the great Alpine chain.” Of the same purport are the remarks of Baron Richthofen on the connection between the distribution of volcanic rocks and elevated regions of the surface. He asks, “ Was the par- ticular structure of certain portions of the crust of the globe, which is indicated by the situation of elevated regions on its surface, among the causes of the eruption of volcanic rocks? or were the inequalities of level on the surface, in the volcanic regions, due to the processes attending and the agencies causing the eruptions? The answer to both these questions must be in the affirmative’.” The same author writing of the mode of geological oc- currence of the rocks which have formed massive or fissure eruptions, says of andesite that “ preeminently the greater part of it has to all appearance been ejected through extensive fissures; that is, 1t has been produced by what are styled mas- sive eruptions...... Andesitic mountains are characterised by monotony in scenery. They form continuous ranges which are often of considerable elevation and extent’.” Again of this rock he tells us that in Hungary, ‘“‘andesite composes entirely the Hargitta-range, which extends over one hundred miles in length and twenty-five in width; the Vihorlat-Gutin-range, which is of still larger dimensions, and the Eperies-Kaschau- range; all of which are densely wooded, and of a gloomy monotonous aspect’.” Similarly he mentions belts and ranges of basalt*. If the eruption of these extensive ranges, through fissures which must have been of great width, was indeed synchronous with the compression that raised the mountains which they skirt, there appears to be no escape from the conclusion that the rending of the fissures was the cause of the compression, because no pressure from beyond, greater than their own, could have 28 OE ay, Mie 1 «¢ Natural System of Volcanic Rocks,” p. 82. 2 Ibid. p. 75. | § Ibid. p. 30. 4 Ibid. p. 27.
