Abstract
Cores of late Quaternary sediments were collected from several sites in Clear Lake (fig. 1). Samples from two of these cores (fig. 2, 3) have been analyzed for their mercury content as part of a study on the time of emplacement of the mercury ore body at the nearby Sulphur Bank mine (fig. 1). The samples were analyzed in laboratories of the U.S. Geological Survey by the mercury vapor detector method (Vaughn and McCarthy, 1964; Vaughn, 1967). The analyses of core 6, except samples 332, 341, 343, 386, 406, and 462, were done by Mr. Kam Leong (Table 1); the remaining analyses were done by Mr. Allen Meier. Analyses of core 10 (table 2) were done by Mr. Meier. Meier reported interference by organic material in the samples he analyzed. Because the two sets of data are not in agreement, most of the samples submitted to Leong and Meier are being reanalyzed.
