(Appendix) Fluid chemistry and strontium isotope data for ODP Hole 168-1026B, supplementary data to: Butterfield, David A; Nelson, Bruce K; Wheat, C Geoffrey; Mottl, Michael J; Roe, Kevin K (2001): Evidence for basaltic Sr in midocean ridge-flank hydrothermal systems and implications for the global oceanic Sr isotope balance. Geochimica et Cosmochimica Acta, 65(22), 4141-4153 by David A Butterfield( )

Previous models and calculations of the global mass balance of Sr in the oceans have shown that the input of unradiogenic basaltic Sr from on-axis midocean ridge hydrothermal systems is much less than needed to balance the input of radiogenic Sr delivered to the oceans by rivers. The implication is that either the oceans are far from steady state with respect to Sr isotope balance (and that the 87Sr/86Sr ratio of seawater is increasing at unprecedented rates) or that there is a significant missing source of basaltic Sr. It has long been recognized that off-axis hydrothermal fluxes might significantly affect the mass and isotopic balance of Sr and other elements in the oceans, but nearly all previous work has concluded that the 87Sr/86Sr ratio of pore fluids in ridge-flank hydrothermal areas is virtually indistinguishable from the seawater ratio or is dominated by authigenic carbonates. In contrast, we report here the 87Sr/86Sr ratios of warm springs, sediment pore fluids, and basement reservoir fluid with a clear basaltic signature from the eastern flank of the Juan de Fuca ridge (JFR). Fluids venting from Ocean Drilling Program Hole 1026B on the Juan de Fuca east flank have relatively stable Sr isotope and major element composition for the 3 yr following drilling. These results and similar results recently reported by Elderfield et al. (1999) indicate that low-temperature ridge-flank hydrothermal circulation has an important effect on the Sr isotope balance in the oceans. If published values for the other major sources of Sr input to the oceans (rivers and axial hydrothermal flux) are accurate, then the rate of increase of the 87Sr/86Sr ratio in seawater (~0.000054 per million years) can be accommodated if ridge flanks on a global scale deliver fluids to the ocean with delta (87Sr/86Sr)/heat ratios one third to one half of the ratio found in warm JFR basement fluids. Based on published Sr and O isotope signatures of calcite veins in the uppermost basaltic ocean crust, the average delta (87Sr/86Sr)/heat ratio of low-temperature fluids is in the range required to balance the oceanic Sr isotope budget. Although the 87Sr/86Sr ratios of the JFR flank fluids in this study overlap with fluid properties inferred from some calcite veins in the upper oceanic crust, the magnitudes of the delta (87Sr/86Sr)/heat ratios of nearly all of the JFR flank fluids are too large to be representative of the average global flank fluid flux; the same has been argued on the basis of the extremely high implied Mg flux
George S. May papers by George May( )

in English and held by 1 WorldCat member library worldwide

The George S. May papers date from 1955-1988 and include materials related to his committee work, notices and publications. Materials are arranged into three series of the same names. The Committees series includes alphabetically arranged files for his service on University committees, service to a variety of Historical agencies in Michigan, and service related to organizing grants and workshops on a variety of topics. The most extensive records in this series are related to the work he did for the University with a variety of committees from the Faculty Council Greivance committee, an advisory committee to the Historic Preservation curriculum, establishment of the University Archives, and the Student Publications committee. Notices are a collection of memorandums and correspondence collected by May. There are three files for Campus notices from a variety of administrators, Faculty notices primarily from Faculty Council (now known as Faculty Senate), and a file for Union notices when the AAUP was organizing on campus. The bulk of this series are the Department notices that are arranged chronologically and were donated annually to the University Archives by May with one gap in this subseries of materials for the year that May was on sabbatical. Publications and Writing series primarily includes articles written by May both prior to and during his tenure at Eastern Michigan University. Most are in relation to Michigan History with a few from his time in Iowa. Included in this series is his sabbatical report submitted to the Unversity as well as a draft of his Automotive History a text he continued to work on in his retirement.The collection does not contain any materials related to the teaching May did while at EMU
