These studies are being conducted to assist the Government of these Islands by providing necessary information for future planning and resource appraisal. The initial phase of the geochemical study was designed to examine the regional geochemical characteristics of the Islands and to identify possible mineralization. (Tucker and others, 1985; Alminas and Tucker, 1987). Geochemical sampling was conducted on the three main islands of St. Croix, St. John, St. Thomas, and numerous smaller islands in the region from 1983 to 1988. Fifteen hundred and ninety six samples were collected and analyzed for 31 elements by emission spectrography and for gold and tellurium by atomic absorption spectroscopy. This open-file reports the analytical results, tables 1-7, for gold, tellurium, and silver in rock and soil samples collected from the study area, and spectrographic results for rock and soil samples, tables 8 and 9, collected in 1986 and 1988. A previous publication (Hopkins and others, 1986) reported analytical results for samples collected in 1983 and 1984. The study was funded by the USGS Virgin Islands project. Study Area The U.S. Virgin Islands are located in the Greater Antilles Island arc some 40 miles east of Puerto Rico (fig. 1). The major islands include St. Croix, St. John, and St. Thomas. There are about 40 smaller islands in the study area concentrated near St. Thomas and St. John. The British Virgin Islands are within a few miles of St. John Island. St. Croix is the largest of the U.S. Virgin Islands, and is located 35 miles south of St. Thomas, it is 22 miles long and 6 miles wide containing 84 square miles. St. John Island is 7 miles long and 3 miles wide, and contains 19 square miles. St. Thomas Island is 12 miles long and 3 miles wide, and contains 30 square miles. The topography of the islands is mountainous. Broad flatlands occur in the central portion of St. Croix. The highest points in the study area are Crown Mountain on St. Thomas, (1,556 ft), Bordeaux Mountain on St. John (1,277 ft), and Mt. Eagle on St. Croix (1,165 ft). The coastline of St. Croix is regular. The coastlines of St. John and St. Thomas are irregular with numerous bays. Small fringing coral reefs are common in shallow water. The climate in the Virgin Islands is maritime tropical. The average annual rainfall at higher elevations is 50-60 inches per year and at lower elevations is 20-30 inches per year. There is no well-defined wet or dry season. The temperature is generally constant between 80 and 85° F. The vegetation is generally not native to the islands and consists of thorny brush and Hurricane grass in the formerly cleared areas. The uncleared portions of the more mountainous areas are covered by dense tropical forest with a few large trees and a dense undergrowth of brushes and vines. There are only a few free-flowing streams and these are frequently intermittent. St. Croix is underlain by strongly-folded upper Cretaceous and gently- folded Tertiary sedimentary rocks, and igneous intrusions with contact metamorphic aureoles of late Cretaceous or early Tertiary age. St. John and St. Thomas are island-arc related Cretaceous to Tertiary volcanic and volcaniclastic rocks, carbonates, and near-surface intrusives. 69° 66 63 60" J> 'X VIRGIN ISLANDS '\ °<P. / \\? fr^-^ ATLANTIC OCEAN «* VIRGIN ^ GO IT.

Alminas and R.E. Tucker. The samples were shipped to the U.S. Geological Survey laboratory in Denver, Colorado for preparation and analyses. Eight hundred and forty six rock and seven hundred and fifty soil samples were collected. Rock chips from outcrop in the vicinity of the soil or stream drainage site were collected when possible. Approximately 1 Ib of rock chips were collected. Rock samples were also collected from altered zones, veins, or dikes whenever encountered. The rocks were crushed and then pulverized using ceramic plates, and the resultant material was analyzed. Most soil samples were collected in the B-horizon. The B-horizon ranged in depth from 10 inches to over 15 inches. Approximately 1 Ib of soil was collected at each site. Soil samples were oven dried at 250 °F for 6 hours as per U.S. Department of Agriculture regulations. The soil samples were disaggregated, sieved through an 80-mesh stainless steel sieve, and analyzed. ANALYTICAL PROCEDURES Each sample was analyzed for 31 elements using a semiquantitative, direct-current arc emission spectrographic method (Grimes and Marranzino, 1968). The elements analyzed and their lower limits of determination are listed in table 10. Spectrographic results were obtained by visual comparison of spectra derived from the sample against spectra obtained from standards made from pure oxides and carbonates. Standard concentrations are geometrically spaced over any given order of magnitude of concentration as follows: 100, 50, 20, 10, and so forth. Samples whose concentrations are estimated to fall between those values are assigned values of 70, 30, 15, and so forth. The precision of the analytical method has been determined to be within one reporting interval 83 percent of the time and within two reporting intervals 96 percent of the time (Motooka and Grimes, 1976). Gold and tellurium were determined in each sample using the atomic- absorption spectroscopic method. A brief description of these procedures follows: Gold A 10-gram sample is roasted for 1 hour at 700 °C, gold is then extracted with hydrobromic acid-0.5 percent bromine solution and MIBK (methyl isobutyl ketone). Flame atomic-absorption spectroscopy is used to determine gold to 0.05 ppm (50 ppb) detection limit, samples below this limit are determined by electrothermal atomic-absorption spectroscopy using background correction to 0.001 ppm (1 ppb) detection limit (O'Leary and Meier, 1986). Tellurium Tellurium is extracted from a 5-gram sample with hydrobromic- acid-2.0 percent bromine solution and MIBK. Ascorbic acid is used to reduce iron interference. Flame atomic-absorption spectroscopy is used to determine tellurium to 0.10 ppm detection limit (O'Leary and Meier, 1986). Results Data results are given in tables 1-9. In each table, column 1 contains the USGS-assigned sample numbers. Most of the sample numbers contain 7 digits. The first digit or first two numerical digits indicate the year of collection. The next two alpha digits indicate the island (SC, St. Croix; SJ, St. John; ST, St. Thomas). The next three numerical digits are the site identifier. The last digit represents the sample type (R, rock; Rl, R2, etc.) additional rock sample in the immediate vicinity; on St. Thomas only, no alpha character indicates a minus-80-stream sediment; an S or B indicates a B-horizon soil sample. Concentration values for As, Au, Cd, Nb, Sb, W, and Th were omitted from tables 8 and 9 since they were determined to be below the limits of determination (table 10) for all samples. Columns 2 and 3 are the sample localities in latitude and longitude. The following columns contain the analytical results. Figure 2 shows sample sites on St. Croix Island for samples collected in 1984 and 1987, figure 3 for 1986 and 1988, and figure 4 is a detailed site map for 1987. St. John sample site map is shown on figure 5. St. Thomas sample site map is shown on figure 6.
