Chert geochemistry discriminant analysis and K-meas cluster analysis: Rampart Project area, Tanana B-1 Quadrangle, east-central Alaska A pilot study using discriminant analysis on major oxide and minor element data from 67 chert samples in the Rampart area, southeastern Tanana and southwest Livengood Quadrangles, western Yukon-Tanana Upland, Alaska, generally indicates a unique geochemical signature for the cherts of a given unit.Chert samples from five known type locales were used as standards of comparison: 1)Livengood Dome Chert (Ordovician), 2)Amy Creek unit (Proterozoic to early Paleozoic), 3)Rampart Group (Mississippian to Triassic), 4)Troublesome Creek unit (Devonian), and 5)Permian-Triassic clastic unit (associated with the Triassic-dated gabbro). Samples from the above units were compared to chert from Tanana B-1 area-units of unknown... Tags: Barium, Bedrock Geologic Map, Chemistry, Chert, Geochemical Data, All tags...
