Chemical relations of rocks and their graphic representation
Authors:
Abstract
Anyone who has sought to gain a clear understanding of the chemical relations of rocks must have seen with striking clarity all the imperfection of our knowledge on this subject. It must be admitted that true, exact science has as yet scarcely touched this important issue, and that the most primitive empiricism prevails here. A great number of rock types are put forward, receiving numerous names, but there is not even a universally recognized criterion for distinguishing one rock type, or, more precisely, one rock variety from another..
