“…Boron content was determined by ICP-optical emission spectroscopy following fusion with Na 2 CO 3 and dissolution with diluted HC1O 4 , a procedure similar to that used by Owens et al (1982). The results of the chemical analyses are compiled in Appendix Tables 1 and 2.…”

Six GEOMETEP cores sampled along a transect about 100 km long centered on the East Pacific Rise are compared with six DSDP Leg 92 cores sampled along a transect 350 to 1250 km west of the crest of East Pacific Rise. The influence of hydrothermal precipitation on the chemical character of the samples from both transects is strong and decreases with distance from the East Pacific Rise. Both the amount and the chemical composition of the hydrothermal precipitates change with distance. Near the rise, the precipitates are enriched in manganese and silica; with increasing distance from the rise the precipitates contain higher proportions of iron. The boron enrichment in the hydrothermal precipitates may outweigh the boron enrichment in marine clay minerals.Hydrothermal production of barite and apatite at the East Pacific Rise is somewhat masked by contributions from the dissolution of calcareous tests. Hydrothermal and residual apatite can be distinguished by their yttrium contents. INTRODUCTIONDuring cruise SO 26 of the GEOMETEP program (geothermal metallogenesis east Pacific) on board the German research vessel Sonne, massive sulfides were dredged in a spreading center of the East Pacific Rise (EPR) at about 20°S Gundlach et al., 1983; Backer et al., in press). Also on that cruise, a 100-km-long transect of six sediment cores was sampled on either side of the EPR at the same latitude. In this chapter, this short GEOMETEP transect is compared with the longer transect (350 to 1250 km west of the EPR) of six DSDP holes from Leg 92 (Fig. 1).In addition to massive sulfides, the EPR in this area produces large amounts of hydrothermal oxide precipitates, which are mainly transported westward by deep water currents (Marchig et al., 1984). This combined transect gave us the opportunity to observe the changes in hydrothermal deposition with time and distance from the EPR. DESCRIPTION OF CORESOf the six GEOMETEP cores, the four farthest from the EPR were sampled with a 4-m-long box corer, and the two cores closer to the EPR were sampled with short piston corers. The box cores consisted of a maximum of 280 cm of sediment, and the piston cores consisted of from 10 to 26 cm of sediment. We do not know whether the collected cores represent the complete profiles down to the basaltic basement, because the box corers may have been stopped by a tephra layer.Six sites drilled with a hydraulic piston corer during DSDP Leg 92 were investigated: Sites 600, 601, and 602Leinen, M., Rea, D.

“…If the sample has high iron concentrations (as encountered in the digests of soil, metals, geological and some biological materials) then the B 249.773 and B 249.678 lines cannot be used because of the overlap of Fe at 249.782 on at B 249.773 nm and Fe at 249.653 on B at 249.678 nm (64). Boron determination by ICP-OES is also affected by other interfering species; for example, Si interferences may render low levels of B determination unreliable (135,136). The presence of Fe, Ni, Cr, Al, and V depressed, while Mn, Ti, Mo, and high concentrations of Na enhanced B signals (33,34,137).…”

“…Reported detection limits for B are 10 to 15 mg B L -1 in soil solutions and plant digests (Spiers et al, 1990). Boron determination by ICP-OES is also affected by other interfering species, for example, Si (Owens et al, 1982;Din, 1984), Ni, Cr, Al, V, Mn, Ti, Mo and high concentrations of Na (Pougnet & Orren, 1986b;Kavipurapu et al, 1993). Nevertheless, recently, Mehlich-3 has been promoted as a "universal" extractant in a wide variety of soils.…”
