Excerpt from Manual of Lithology: Treating of the Principles of the Science, With Special Reference to Megascopic Analysis
Bulk analyses of rocks are given in the books on the subject, and rock groups created from chemical differences. The researches of Lang conclusively Show that nothing can she thus based, as the same rock will Show a varying bulk analysis when fresh and weathered, and the same mineral group will vary widely in the components of a bulk analysis; while rocks of varying mineral composition will agree closely in bulk analyses. The rock groups of the future must, therefore, depend more on mineral than chemical composition. While the majority of authorities define an acid rock as one whose bulk analysis shows a certain percentage of silica, Lessing says that it is one that carries a surplus of silica after saturating the bases, no matter how great or small that may be. The terms acid and basic are indefinite terms, and bulk analyses are misleading.
