“…A portion of traverse C, from a study site of Erdman et al (1988) near Hot Springs Ranch in the Gold Run District, Humbolt County, Nevada seemed to meet all of the above requirements. Figure 2 shows the location of traverse 1 where luminescence measurements were made.…”

“…Erdman et al (1988) have done chemical analysis of big sagebrush (Artemisia tridentata) in Nevada and found many plants to contain anomalous levels of gold. There has also been a significant effort by the Branch of Geophysics to collect data in the area using other geophysical techniques.…”

“…Erdman et al (1988). The FLD luminescence data were collected from sagebrush and adjacent ground areas along a path corresponding to traverse C (figure 4, Erdman et al, 1988). The reference map is Goldrun Creek Quadrangle, Nevada-Humbolt Co. 7.5 minute series.…”

Open-File Report 89-107This report is preliminary and has not been reviewed for conformity with U.S, Geological Survey editorial standards. (Any use of trade names is for descriptive purposes only and does not imply endorsement by the USGS.) ABSTRACTRecent advances in the understanding of the role of chlorophyll fluorescence in the detection of stress conditions in plants has led to the desire to apply this tool to mineral exploration. The Fraunhofer line discriminator (FLD) has been used to detect differences in chlorophyll fluorescence indicating plant stress in citrus. An experiment was conducted to determine the possibility of detecting chlorophyll fluorescence differences which might result from anomalous concentrations of gold in sagebrush. The plants were apparently dormant and the results are inconclusive.
