Show UTAH A GREAT MINING STATE I 1 some idea of the magnitude and importance ot of the mineral resources and mining industry of 0 utah may be md had from a volume just published as professional paper by the united S tates states geological survey department ot of the interior entitled the ore deposits of 0 utah by B S butler G P F loughlin Lou ghUn V C halkes Hel kea and others the volu volume me contains nearly quarto pages and many maps and other illustrations including a geologic map ot of utah and brings together practically all available information on an the ore deposits of the tha state especially as regards regard ii their geologic relations the report consists 0 of two parts parti part I 1 deals with the geography and geology of 0 utah as a whole and describes the ore deposits by classes and the manner in which they were formed it contains also a history ot of mining development in the state and very full data on its metallic output it shows that in value the metal having the largest output Is copper which Is very closely followed by silver lead follows then gold and last lagging tar far behind ill the others comes zinc in productivity AS measured by value of output the vest 1 mountain fountain or bingham district easily leads its output being about ire ice that thai vr ot ahe he distri t tairi ru pat r rit the itak city is 13 vei neacy ir to that ot of the ta rn r ilc ife and Is eater e ater than the rna cour bained output S f all the ottle ie z tricks in the state except the and the BInghi tin measured fy by value nearly half the metal prod produced aced in the state has come from the bingham district the gintic tintic district t brict has produced more gold than tha n any other district in the state hut but its record Is nearly equaled by that of the bingham the park city district leads in output of silver but blit the Is a close second in output of copper the bingham district Is far ahead more than flye fire sixties of the copper produced in utah has come coine from that district practically all the minerals that occur in utah in connection with the ore deposits are listed and described and the relations of the various classes of ore deposits to geologic structure and igneous intrusions are fully discussed in part 11 II which constitutes about two thirds of the volume the geology and ore deposits of individual mountain ranges or districts are described bed some of them in considerable detail finally in an appendix george 11 girly one of the geological surveys specialists on fossils describes the characteristic fossils of the carboniferous and triassic beds in the state and shows their form and general features by halftone half tone toile plates by means of these plates and others elsewhere in the volume showing the forms of the cambrian silurian devonian and jurassic fossils mining nien men who have no special knowledge of fossils should be able to determine the geologic age of any beds in which these fossils occur and so gain clues to features of structure hat may have had a great deal to do with the deposition of the ore thus a branch of science that seems not to be directly practical n its alms aims may be put to very practical ise in prospecting for ore |
