596. If, in addition to granite, several formations are displayed which bear traces of the same mode of origin, of the same component parts and the same aggregation, it may be inferred that they are only metamorphoses of the same precipitate. Granite is the basis of geogeny.
597. Granite is a totality for the earth, it is a representation of the three terrestrial elements under the form of identical earth; it is the earth represented in silex, water in clay, and air in talc; it is an universe represented individually in the earth-elements.
598. The granite can undergo metamorphosis in only three ways; for its essence is indeed only trinity. Nothing can individualize itself from granite but quartz, feldspar, and mica. All the formations of this period are thus quartz, feldspar, or mica formations. The granite appears under a threefold form as quartz, feldspar, and mica-granite.
599. The first quartz formation is properly the granite itself, and its character will be also the determinant for all the metamorphoses of quartz—quartz-granite.
600. The first structure, in which the character of feldspar as regards its laminated form and its more argillaceous nature obtains the preponderance, is Gneiss—Feldspar-granite.
601. The first structure in which mica is the predominant character, is the Mica-schist—Mica-granite.
602. All rocks that do not belong to the calcareous formation come under these three forms. The progressive formation of the earth takes a threefold course, since it begins in a threefold and yet single manner in granite.
603. The gneiss and mica-schist precipitations followed subsequently to the completion of granite. For all precipitation is a true process, in which water has a certain tension peculiar to this process, by virtue of which this form of earth and no other has been produced.
604. By granite the silicious principally came out of water, but what was argillaceous and talcose remained behind.
605. Gneiss and mica-schist are indeed subdivided granite, but not in the sense of the already perfected granite having been again stirred up and dissolved, but as already separated in principles, in the primary water.
