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.
Journal ArticleDOI

TL;DR: The depth of oxygen penetration and microbial activity in marine sediments varies by region as mentioned in this paper, and the depth of microbial communities varies with the region of interest, and the microbial communities can be found up to 75 meters below the sea floor.
Journal ArticleDOI
Subsurface structure of a submarine hydrothermal system in ocean crust formed at the East Pacific Rise, ODP/IODP Site 1256
Jeffrey C. Alt,Christine Laverne,Rosalind M. Coggon,Rosalind M. Coggon,Damon A. H. Teagle,Neil R. Banerjee,Sally Morgan,C.E. Smith-Duque,Michelle Harris,L. Galli +9 more
TL;DR: In this article, ODP/IODP hole 1256D penetrates an in situ section of ocean crust formed at the East Pacific Rise, through lavas and sheeted dikes and ∼100 m into plutonic rocks.
Journal ArticleDOI
Channelling of hydrothermal fluids during the accretion and evolution of the upper oceanic crust: Sr isotope evidence from ODP Hole 1256D
Michelle Harris,Rosalind M. Coggon,C.E. Smith-Duque,Mark E. Cooper,James A. Milton,Damon A. H. Teagle +5 more
TL;DR: 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.
Journal ArticleDOI
Seafloor basalt alteration and chemical change in the ultra thinly sedimented South Pacific
Guoliang Zhang,C.E. Smith-Duque +1 more
TL;DR: In this article, the authors report detailed petrographic and geochemical analysis of basalt cores from these sites in order to investigate what impact sediment insulation has on seafloor alteration beyond 10-15 Myr of ocean crust formation.
