..., and other base metals on the North American continent (Figures 1 – 3 ). Mineralization in the form of lead, zinc, copper, iron, and other metal sulfides, as well as barite and fluorite ranges from trace to ore-deposit scale in the Cambrian through the Lower Ordovician carbonates in most of the North...

... with which hot springs are impregnated agree with those discharged in a gaseous form from volcanoes. (Lyell 1855, p. 608). An alternate ore-forming theory, based on the concept of lateral secretion and concentration of ore and gangue elements from the enclosing host rocks via aqueous fluids, was also...

... ideas on ‘lateral secretion’ as an ore-forming process, and one of the causes of primary geochemical halos surrounding mineral deposits that could be used as guides to their presence. Bob, born June 3rd 1920, grew up near Wallaceburg in southwestern Ontario. It was there that he developed his...

...Isabel Barton ABSTRACT This paper analyzes how the Western concept of minerals evolved over time. Greco-Roman philosophers saw minerals as a form of plant that yielded useful metals or medicines. Most of their data came from mines and focused on ore minerals, but medicinal uses were more highly...

... can the lateral secretion process account satisfactorily for the enhanced metal contents of veinlet-rich rock volumes because only centimeter-scale redistribution of the sulfide mineral(s) is supposed to have taken place. Acceptance of these arguments would appear to rule out the widely promoted...

In the Keweenaw, these familiar and anticipated ores of sulfides and other copper compounds...

However, this can be explained by the also threatened cost of remodeling plants and processes to handle new types of ore, and the threat of having these revised operations wiped out by later discoveries of “conventional” deposits producible with older lower...

... monzonite porphyry. The two-layer IP interpretation predicted mineralization to occur at a depth of 1000 ft depth. Later drilling found the depth to be 1100 ft. This case history may be the earliest example of an IP base metal “discovery,” at least in North America. The small resistivity contrast between...
