Geochemical data for alkaline igneous rock units in the Cripple Creek district, Colorado USA: 1989-2016

New major and trace element geochemical analyses of alkaline igneous rocks in this area. of historic gold mining in order to characterize the tellurium and other trace element constituents of predominantly unaltered rocks genetically associated with mineralization, to help understand the mechanism of enrichment in these deposits. 75 samples were analyzed by a variety of modern techniques and instruments.
