Excerpt from Chemical yses of Igneous Rocks Published From 1884 to 1900<br/><br/>It is noteworthy that this attitude of mind obtains, not only among beginners, but among the foremost workers in the science. There are, it is true, some instances of the application of expressed criteria in the selection of yses in well-known papers, but in all these cases the criteria applied are few, and quite inadequate to the purpose, being confined, for the most part, to the freshness of the rock. In few cases does there seem to be any recognition of the difficulties and uncertainties of ytical work or any practical acquaintance with its methods. It goes without saying that this way of regarding yses is totally at variance with the best interests of the science. yses constitute the basis of much of the investigations and discussions with which petrographers and petrologists must occupy themselves, and it is surely not the part of wisdom to erect elaborate structures on foundations of whose stability and careful workmanship we are not assured. It will be time saved in the end, and the superstructure, however well built in itself, will have a far better chance of withstanding the ravages of time and the attacks of critics if all the rotten and unsound blocks in the foundation are removed and only the best and strongest of material retained.

Paperback. Zustand: New. Print on Demand. This book examines the analytical methods of igneous rock chemistry and the criteria for judging the quality of rock analyses that emerged during the late 19th century. The author's purpose, in part, was to encourage a more rigorous and critical approach to rock analysis within the field of petrography. The book explores the complexities of rock analysis, common analytical errors, and ways to account for them. The author's emphasis on accurate and representative analysis signaled a turning point for the field of igneous petrology, as it facilitated more reliable and standardized practices.
