These studies are being conducted to assist the Government of the Islands by providing necessary information for future plan ning and resource appraisal. The initial phase of the geochemical study was designed to examine the regional geochemical characteristics of the Islands. The U.S. Virgin Islands are located in the Greater Antilles island arc some 40 miles east of Puerto Rico (figure 1). The major islands include St. Thomas, St. John, and St. Croix. There are about 50 smaller islands in the study area, concentrated near St. Thomas and St. John. St. Thomas is 12 miles long by approximately 3 miles wide and contains some 19,000 acres. St. John is 7 miles long, on the average is 3 miles wide, and contains some 12,000 acres. The topography of both islands is mountainous. The highest elevation on St. Thomas is 1556 feet (Crown Mountain) and 1277 feet on St. John (Bordeaux Mountain). The islands have very irregular coastlines with many bays and offshore islets. There are only a few free-flowing streams, and these are intermittent at certain elevations. The climate is tropical, but annual rainfall is generally less than 50 inches in the higher elevations. Many of the small outer islands receive much less rainfall and are considered arid. Second-growth forests now cover much of both islands which were formally cultivated fields or plantations. The geology of St. Thomas and St. John has been studied by many researchers including Cleve (1871, 1881), Earle (1924), Meyerhoff (1926), and more recently by Donnelly (1959, 1966). The general structural relationships have been taken from Donnelly (1966). The oldest rocks in the study area occur along the southern coasts of both islands. These rocks are a series of felsic tuffs, flows, and small intrusives. Mafic dikes and radiolarite beds are found locally within the felsic sequence and are collectively called the Water Island Formation. The Louisenhoj Formation unconformably overlies the Water Island Formation. This unit is a sequence of pyroclastic to epiclastic rocks composed of augite andesite. The central region of St. Thomas and the northern third of St. John are composed of these rocks. Overlying the Louisenhoj Formation is the Outer Brass Limestone. The Tutu Formation overlies the Outer Brass Limestone and consists of fine- to coarse-grained volcanic wackes and limestone. The Hans Lollik Formation overlies the Tutu Formation and crops out on Hans Lollik Island. This unit is similar in texture and composition to the Louisenhoj Formation. SAMPLE COLLECTION, PREPARATION AND ANALYSIS Rock, soil, minus-80-mesh stream sediment, and panned concentrate samples were collected during two field sessions (in 1983) from St. Thomas and St. John, U.S. Virgin Islands. Drainage basins with an areal extent generally less than 0.25 square miles were sampled. At each drainage site four different samples were collected. A 10- to 15-pound composite sample of the sediment was collected for panning. A 0.5-pound composite sample was 1 59. 66 ATLANT;C OCEAN s r„, v , R GIN GLANDS 'D 0 DOMINICAN 4 ( REPUBLIC VIRGIN coo "' RDA PUERTO CO \ ST. JONN 0 s-.

A 0.5- to 1-pound soil sample was collected near the sediment site and, when present, approximately 1 pound of rock chips were collected from a outcrop. At some drainage basin sites and areas where no drainage basin was developed, a 10- to 15-pound soil sample was collected and panned as well as a minus-80-mesh and outcrop sample. It should be noted that few drainage basins showed the rather classic sediment development observed in the western United States. The sample localities for St. Thomas and St. John are given in figures 2 and 3, respectively. All the samples were oven dried at 250°F for approximately six hours, except the panned concentrates, which were air dried. The soils were disaggregated, sieved, and the minus-80-mesh fraction was analyzed. The rocks were pulverized using ceramic plates. The panned concentrate samples were sieved to minus-20-mesh then placed in bromoform (density 2.86) to separate two mineral fractions relative to their densities. The light fraction contains minerals such as feldspars, quartz, and calcite. The heavy-mineral fraction may contain rock-forming minerals such as biotite, amphiboles, pyroxenes, accessory minerals such as magnetite, illmenite, sphene, zircon, and monazite and primary and(or) secondary minerals related to metallization processes such as metal sulfides, sulfates, carbonates, and oxides. The magnetite and other very magnetic minerals were removed using a hand magnet. Further mineral separation was completed using a Frantz Isodynamic Separator with a forward slope of 25° and side slope of 15°. A setting of 0.2 amperes was used to remove any very magnetic minerals left in the concentrate. The concentrate was run through the Frantz a second time at a setting of 1.0 amperes. A magnetic fraction, those minerals attracted by the magnet, and a nonmagnetic fraction were collected and analyzed. The minerals are separated by the Frantz on the basis of varying magnetic susceptibility (Flinter, 1959; Hess, 1956; Nickel, 1968 and 1969) which depends primarily on the degree of paramagnetism exhibited by the mineral. The paramagnetic properties ikf i. a mineral often reflect the amount of paramagnetic ions such as Fe' in the crystal lattice (Hurlbut, 1971; McAndrew, 1957; and Rosenblum, 1958). All samples were analyzed by the six-step D.C.-arc semiquantitative emission spectrographic method (Grimes and Marranzino, 1968) for 31 elements. All of the analytical values are reported as six steps per order of magnitude (1, 1.5, 2, 3, 5, 7 or multiples of 10). These values approximate the geometric midpoints of successive concentration ranges (Grimes and Marranzino, 1968). This analytical method utilizes a series of elemental standards against which the elemental concentrations in the samples are compared. If a sample contains elemental concentrations above the highest standard used (table 1), the elemental concentration is represented by a "greater than" symbols (>) before the upper standard. If a sample contains elemental concentrations below the lowest standard (table 1), two code designations can be assigned for the elemental concentration. If the sample concentration is slightly below the lowest standard, the elemental concentration is represented by a "less than" symbol (<) before the lower standard. If the sample concentration is not detected, the elemental concentration is given and "N" code. The six-step D.C.-arc emission spectrographic method provides reproducibility within one geometric interval of the reported value approximately 86 percent of the time 3 *ALES .5 0 I WO..

The analytical results for the soils, rocks, and minus-80-mesh fraction of the stream-sediment samples are given in tables 2, 3, and 4, respectively. A representative split of the magnetic and nonmagnetic fraction from the panned concentrate was pulverized in an agate crucible and analyzed by a modified version of the six-step D.C.-arc semiquantitative emission spectrographic method described by Grimes and Marranzino (1968). A modification of the method was necessary for the analysis of the nonmagnetic heavy-mineral-concentrate samples to eliminate spectral interferences produced by matrix effects characteristic of this sample type. The effect of this modification was a loss of sensitivity resulting in an increase of all lower limits of determination by two geometric intervals. The analytical results for the magnetic and nonmagnetic fractions of the panned concentrates are given in tables 5 and 6, respectively. An oxalic acid leach was performed on the mineral grains less dense than bromoform from the panned concentrate fraction. The size fraction was minus- 20-mesh to approximately plus-80-mesh. The oxalic acid dissolved the Fe-Mn coatings on the mineral grains (Alminas and Mosier, 1975). Twenty-five ml of a 5% oxalic acid solution (weight/volume) was added to 5 g of sample and boiled for 10 minutes. The hot leachate was filtered, evaporated to dryness, then heated for 4 hours at 450°C to roast off the oxalate. The oxide powder was analyzed by the six-step D.C.-arc emission spectrographic method. The data results are given in table 7. REFERENCES CITED Alminas, H. V., and Mosier, E.
