Ore Deposits A Discussion RePublished From The Engineering And Mining Journal New York May 1903
Author: Anon

The discussion on ore-deposits which appears in this pamphlet is a reproduction of the views expressed before the Geological Society of Washington, at two consecutive monthly meetings, early in 1903, as reported in the Engineeringd and dfining Journal, but it also includes some important corrections and amplifications of the material previously ... more »published. In a manner-timely and suggestive-it represents the latest opinions on a subject which is of perennial interest to all those who are engaged either in the academic or the practical pursuit of the ore-bodies valuable to man. The discussion gives particular prominence to the recent accentuation of magmatic differentiation as a factor in the distribution of ores in rocks this is the reason why the advocates of the agency of water as a determinative process are not so prominent. Mr. Emmons, Prof. Van Hise and other suthoritative writers have indeed taken part in the discussion and added largely to the value of it, but their purpose has been evidently more to warn against the exaggeration of a new motif in the geologic drama than to reiterate their own views fully until the new theories have been further substantiated. The present position of the study-it is not yet an exact science-of ore-deposits is worthy of a brief review. It is summaried herewith in words whose repetition1 seems warranted as an introduction to the discussion on which the present pamphlet is based. Mining owes much to geology. This debt will, let us hope, be increased, for it is an honorable obligation. S ience justifies herself to the commercial world by the practical aidwhich she gives to industry. Even those who delve underground for the metals upon - which mod-1 From an article in the Engineering and Mining Jowml of Jan. 18,1902, entitled Recent Progress in the Study of Ore-Deposits, by T. A. Rickard. . ern ei ilizati6n depends are not without the realization that light has come to them in dark places. Geology was not always a friend to mining. In its infancy it made wild statements which only perplexed an exceedingly venerable industry. Even to this day, in certain quarters, there is an unspoken idea that the young science stoops to commercialism when she concerns herself with matters which have to do with mining. A notable example can be instanced. The Geological Society of England was founded by the fathers of modern geology, by men whose names are household words, and among its records will be found the first presentment of the very foundations of the science to which the society is dedicated. ...
