Overview

Excerpt from Gold: Its Geological Occurrence and Geographical Distribution The writer who would add one more treatise to the litera ture of the study of ore-deposits must needs show justification. He must present either new facts or a new and more scientific arrangement of already-published data. It is hoped that, to some degree at least, both these ends have been attained in the present volume. In order that the value of the collected facts may be in no wise impaired by possibly erroneous correlation, speculative inferences have here been sharply differentiated from the data of Observation. This arrangement of the subject is presented with the more con fidence since it is believed that absolute progress in the science of ore-deposits will, in the future, be made largely, if not entirely, by inductive reasoning. A compilation Of the known facts concerning the deposition of a single metal, and of one possessing fairly well-defined characters, both native and in combination, has therefore seemed a not unnecessary contri bution towards the foundation on which a stable hypothesis of ore deposition must be erected. The correlation of the data Obtained has for the present been considered of minor importance, and every effort has, on the other hand, been directed towards the presentation in readily accessible form of the salient facts of auriferous deposition.
