...L. Kenneth Wilson Abstract Exploitation of tungsten orebodies in a silver-lead district has revealed new data, in conflict with published accounts of Darwin ore genesis. Knopf's assignment in 1913 of pyrometasomatic origin was contested by Kelley, who, in 1937, suggested mesothermal classification...

...-Chilean Mining Company. 16 Miers was a mining engineer who came to Chile to develop copper mines, at which he did not succeed. 17 In 1835 Darwin stayed with Caldcleugh in Santiago and wrote of his host: I staid also a week in St Iago, to rest after the Cordilleras, of which I stood in need...

In different mining districts, faults were also referred to as “dykes” or, perhaps more tellingly, “slip-dykes.” Thus W. D. Conybeare, quoted...

..., and properly, been significant. Thus, when Alfred Russell Wallace (1823-1913) declared his hand concerning natural selection, he inadvertently flushed out the reluctant Charles Darwin (1809–1882). Darwin was distressed when informed that Wallace had had parallel thoughts. 3 Happily, at short notice...
