Further Biogeochemical Data from the San Manuel Copper Deposit, Pinal County, Arizona
Although the copper and zinc contents of plants in the vicinity of the San Manuel Copper Deposit are not particularly high, they are much higher than those of similar species in similar climatic areas remote from copper mineralization. Some plants, notably California Poppy, Poppy, Paloverde, Creosote bush, and Scrub oak may be useful to the biogeochemist. Others, such as the Saguaro and Ocotillo, appear from this preliminary study to be less promising.
