Stable isotope geochemistry by John W Valley( Book )

18 editions published between 2001 and 2019 in English and held by 496 WorldCat member libraries worldwide

This book illustrates how isotope ratios in minerals, rocks and fluids provide evidence for understanding a wide range of natural phenomena including: paleoclimate, marine sedimentation, geomicrobiology, biogeochemical cycles, thermal history, hydrothermal/ metamorphic fluid flow, and igneous petrogenesis. Emphasis on O, C, H, and S isotopes - and the principles of equilibrium and kinetic isotope exchange

Stable Isotopes in High Temperature Geological Processes( )

2 editions published in 2018 in English and held by 14 WorldCat member libraries worldwide

Volume 16 of Reviews in Mineralogy inroduces to high-temperature stable isotope geochemistry and should provide an entry into the pertinent literature, as well as some understanding of the basic concepts and potential applications.The first three chapters focus on the theory and experimental data base for equilibrium, disequilibrium, and kinetics of stable isotope exchange reactions among geologically important minerals and fluids. The fourth chapter discusses the primordial oxygen isotope variations in the solar system prior to formation of the Earth, along with a discussion of isotopic anomalies in meteorites. The fifth chapter discusses isotopic variations in the Earth's mantle and the sixth chapter reviews the variations in the isotopic compositions of natural waters on our planet. In Chapters 7, 8, 9 and 10, these isotopic constraints and concepts are applied to various facets of the origin and evolution of igneous rocks, bringing in much material on radiogenic isotopes as well, because these problems require a multi-dimensional attack for their solution. In Chapters 11 and 12, the problems of hydrothermal alteration by meteoric waters and ocean water are considered, together with discussions of the physics and chemistry of hydrothermal systems and the 18O/16O history of ocean water. Finally, in Chapters 13 and 14, these concepts are applied to problems of metamorphic petrology and ore deposits, particularly with respect to the origins of the fluids involved in those processes
The role of fluids during metamorphism of marbles and associated rocks in the adirondack mountains, new york by John W Valley( )

4 editions published between 1980 and 1985 in English and held by 4 WorldCat member libraries worldwide

Calcites from granulite facies marbles are similar in (delta)('18)O to those from lower grades and from unmetamorphosed limestones of the same age. Isotopic exchange is seen across marble-anorthosite contacts at the scale of only a few meters. Sedimentary isotopic compositions have been preserved in the core of the Cascade Slide xenolith and in interlayered non-calcareous metasediments. Mass balance calculations of the isotopic effects of pervasive fluid migration and volatilization suggest that if

Stable oxygen isotope ratios in zircons from oceanic crust, supplementary data to: Grimes, Craig B; Ushikubo, Takayuki; John, Barbara E; Valley, John W (2011): Uniformly mantle-like d18O in zircons from oceanic plagiogranites and gabbros. Contributions to Mineralogy and Petrology, 161(1) by Craig B Grimes( )

in English and held by 1 WorldCat member library worldwide

Lower ocean crust is primarily gabbroic, although 1-2% felsic igneous rocks that are referred to collectively as plagiogranites occur locally. Recent experimental evidence suggests that plagiogranite magmas can form by hydrous partial melting of gabbro triggered by seawater-derived fluids, and thus they may indicate early, high-temperature hydrothermal fluid circulation. To explore seawater-rock interaction prior to and during the genesis of plagiogranite and other late-stage magmas, oxygen-isotope ratios preserved in igneous zircon have been measured by ion microprobe. A total of 197 zircons from 43 plagiogranite, evolved gabbro, and hydrothermally altered fault rock samples have been analyzed. Samples originate primarily from drill core acquired during Ocean Drilling Program and Integrated Ocean Drilling Program operations near the Mid-Atlantic and Southwest Indian Ridges. With the exception of rare, distinctively luminescent rims, all zircons from ocean crust record remarkably uniform d18O with an average value of 5.2? 0.5 per mil (2SD). The average d18O(Zrc) would be in magmatic equilibrium with unaltered MORB [d18O(WR) 5.6-5.7 per mil], and is consistent with the previously determined value for equilibrium with the mantle. The narrow range of measured d18O values is predicted for zircon crystallization from variable parent melt compositions and temperatures in a closed system, and provides no indication of any interactions between altered rocks or seawater and the evolved parent melts. If plagiogranite forms by hydrous partial melting, the uniform mantle-like d18O(Zrc) requires melting and zircon crystallization prior to significant amounts of water-rock interactions that alter the protolith d18O. Zircons from ocean crust have been proposed as a tectonic analog for>3.9 Ga detrital zircons from the earliest (Hadean) Earth by multiple workers. However, zircons from ocean crust are readily distinguished geochemically from zircons formed in continental crustal environments. Many of the>3.9 Ga zircons have mildly elevated d18O (6.0-7.5 per mil), but such values have not been identified in any zircons from the large sample suite examined here. The difference in d18O, in combination with newly acquired lithium concentrations and published trace element data, clearly shows that the>3.9 Ga detrital zircons did not originate by processes analogous to those in modern mid-ocean ridge settings
