“…The results are shown in Table 9. Our results compare favorably with the Abbey's (1983) usable values despite the difference in weight basis (as received versus dry-weight basis). The precision for these replicate measurements was about Q% RSD which is typical of our results for a wide variety of silicate rocks.…”

“…They were measured after every ten samples to check for instrument drift. USGS standards QLO-1, RGM-1, SCo-1, BHVO-1, and SDC-1 [Abbey, 1983;Gladney and Roelandts, 1988;Govindaraju, 1994;Flanagan, 1976] were also analyzed and used to routinely correct measurements.…”

Constraints on mineralization, fluid‐rock interaction, and mass transfer during faulting at 2–3 km depth from the SAFOD drill hole

et al. 2009

[1] Mineralogical and geochemical changes in mudrock cuttings from two segments of the San Andreas Fault Observatory at Depth (SAFOD) drill hole (3066-3169 and 3292-3368 m measured depth) are analyzed in this study. Bulk rock samples and hand-picked fault-related grains characterized by polished surfaces and slickensides were investigated by X-ray diffraction, electron microscopy, and geochemical analysis. The elemental changes in fault-related grains along the sampled San Andreas Fault are attributed to dissolution of detrital grains (particularly feldspar and quartz) and local precipitation of illite-smectite and/or chlorite-smectite mixed layers in fractures and veins. Assuming ZrO 2 and TiO 2 to be immobile elements, systematic differences in element concentrations show that most of the elements are depleted in the fault-related grains compared to the wall rock lithology. Calculated mass loss between the bulk rock and picked fault rock ranges from 17 to 58% with a greater mass transport in the shallow trace of the sampled fault that marks the upper limit the fault core. The relatively large amount of element transport at temperatures of $110-114°C recorded throughout the core requires extensive fluid circulation during faulting. Whereas dissolution/precipitation may be partly induced by the disequilibrium between fluids and rocks during diagenetic processes, stress-induced dissolution at grain contacts is proposed as the main mechanism for extensive mineral transformation in the fault rocks and localization of neomineralization along grain interface slip surfaces.

Boron systematics of Hisatsu and Kirishima basaltic rocks from southern Kyushu, Japan

et al. 2010

To evaluate the effect of slab-derived fluids from subducted Philippine Sea plate on mantle composition beneath southern Kyushu, we determined the boron (B) contents in basaltic rocks from Hisatsu volcanic province and Kirishima volcano, which erupted since 7.6 Ma. Since B is distinctively concentrated into slab-derived fluids, we have attempted to estimate the influence of subduction-related inputs on the composition of the sub-arc mantle based on the B systematics of the basaltic rocks.Old ( These observations indicate that B-rich fluids from Philippine Sea plate were added to the mantle beneath Kirishima volcano between 0.4 and 0.3 Ma. Therefore the modern fluid input from the subducted slab to the subarc mantle may be limited beneath the volcanic front in this area.Keywords: boron, Philippine Sea plate, southern Kyushu, subduction zone, basalt Chaussidon and Marty, 1995;Sun and McDonough, 1989) as they have had no interaction with subducted slabderived fluid and/or melt.In order to identify the involvement of the subducted slab-derived hydrous fluid in the mantle wedge, we employ fluid-mobile/immobile element ratios (B/Sm, B/Zr, B/Nb and Ba/Zr). Previous works (Leeman and Sisson, 1996;Ishikawa and Nakamura, 1994;Ishikawa and Tera, 1997;Ishikawa et al., 2001;Tonarini et al., 2004;Sano et al., 2001) indicate that B/Sm, B/Zr and B/Nb ratios are sensitive indicators of the involvement of the subducted slab-derived fluid because of the following: (1) Since B and Nb have similar solid/melt distribution coefficients under upper mantle and crustal conditions, B/Nb ratios are not significantly controlled by partial melting and fractional crystallization processes; (2) B and the preceding three elements have entirely different chemical behaviors in fluid-related processes. The mobility of B in fluid is distinctly higher than those of Sm, Zr and Nb; (3) The enrichment of B/Nb does not reflect the crustal assimilation process because the B/Nb ratio in the crustal rocks is negligibly low (continental crust: 0.4-0.7;Wedepohl, 1995).
