TLDR
ODP Hole 1256D in the eastern equatorial Pacific is the first penetration of a complete section of fast spread ocean crust down to the dike-gabbro transition, and only the second borehole to sample in situ sheeted dikes after DSDP Hole 504B as discussed by the authors.About:

Copper and zinc isotope systematics of altered oceanic crust at IODP Site 1256 in the eastern equatorial Pacific
TL;DR: In this paper, the authors presented the first combined Cu and Zn isotopic study of altered oceanic crust (AOC) at IODP Hole 1256D that penetrates a volcanic section, a lava-dyke transition zone, a sheeted dyke complex, and a plutonic complex.

Mobility of Au and related elements during the hydrothermal alteration of the oceanic crust: implications for the sources of metals in VMS deposits
TL;DR: In this article, a sample suite of samples was analyzed for Au, As, Sb, Se and Te using low detection limit methods, and a mass balance of metal mobility has been carried out through comparison with a fresh Mid-Oceanic Ridge Basalt (MORB) glass database.
Journal ArticleDOI
Sulphide mineral evolution and metal mobility during alteration of the oceanic crust: Insights from ODP Hole 1256D
TL;DR: Fluxes of metals during the hydrothermal alteration of the oceanic crust have far reaching effects including buffering of the compositions of ocean and lithosphere, supporting microbial life as mentioned in this paper.

Hydrothermal fault zones in the lower oceanic crust: An example from Wadi Gideah, Samail ophiolite, Oman
Barbara Zihlmann,Samuel Müller,Rosalind M. Coggon,Jürgen Koepke,Dieter Garbe-Schönberg,Damon A. H. Teagle +5 more
TL;DR: In this paper, the authors describe a hydrothermally-altered fault zone that crops out in the Wadi Gideah in the layered gabbro section of the Samail ophiolite of Oman.

Geochemistry of gabbro sills in the crust-mantle transition zone of the Oman ophiolite: implications for the origin of the oceanic lower crust
TL;DR: Gabbroic sills intruding dunite in the crust-mantle transition zone (MTZ) of the Oman ophiolite have textures and compositions very similar to those in modally layered gabbros that form the lower part of the gabbro section in the oophiolite as mentioned in this paper.

Reconstructing past seawater Mg/Ca and Sr/Ca from mid-ocean ridge flank calcium carbonate veins
TL;DR: Past oceanic Mg/Ca and Sr/Ca ratios are estimated from suites of 1.6- to 170-million-year-old calcium carbonate veins that had precipitated from seawater-derived fluids in ocean ridge flank basalts to indicate that before the Neogene, oceanic Cation ratios were lower than in the modern ocean.

TL;DR: The depth at which gabbro was reached confirms predictions extrapolated from seismic experiments at modern mid-ocean ridges: Melt lenses occur at shallower depths at faster spreading rates.

Variable Quaternary chemical weathering fluxes and imbalances in marine geochemical budgets
TL;DR: It is suggested that the pulse of rapid chemical weathering initiated at the last deglaciation has not yet decayed away and that weathering rates remain about two to three times the average for an entire late Quaternary glacial cycle.
