Geochemical analyses of rock, soil, and stream sediment samples from the Big Frog Wilderness Study Area, Polk County, Tennessee and Fannin County, Georgia
Semiquantitative spectrographic analyses for 31 elements and atomic absorption analyses for gold and zinc on 43 stream sediments, 5 panned concentrates, 65 soils, and 81 rock samples from the Big Frog Wilderness Study Area and vicinity, Polk County, Tennessee, and Fannin County, Georgia, are reported here in detail. Locations for all 194 samples are given in Universal Transverse Mercator (UTM) coordinates. Rocks analyzed include metasiltstone, metasandstone, metaconglomerate, slate, and vein quartz. The data contain no obviously anomalous values that might be related to economically recoverable mineralization.
Geochemical analyses of rock, soil, and stream sediment samples from the Citico Creek Wilderness Study Area, Monroe County, Tennessee
Semiquantitative spectrographic analyses for 31 elements and atomic absorption analyses for gold and zinc on 119 stream sediments, 14 panned concentrates, 128 soils, and 192 rock samples from the Citico Creek Wilderness Study Area and vicinity, Monroe County, Tennessee, are reported here in detail. Locations for all 453 samples are given in Universal Transverse Mercator (UTM) coordinates. Rocks analyzed include metasandstone, metaarkose, metagraywacke, metaconglomerate, slate, phyllite, and vein quartz. The data contain no obviously anomalous values that might be related to economically recoverable mineralization.
