Special Publication 148
This volume considers the geological processes at and biological colonization of, deep ocean spreading centres from both a modern, for example Mid-Atlantic Ridge, the East Pacific and the South West Indian Ridge, and an ancient perspective, such as in the UK, Cyprus, Turkey, Greece and the Urals.
The book is one of the first attempts to bring together researchers from disciplines as diverse as geophysics and biology studying modern active hydrothermal systems and the fossilized remains of long-extinct hydrothermal systems that are now locked in the geological record.
By using new knowledge of how hydrothermal systems function we can aid the understanding and prediction of mineral deposits now found on land.
Contents Preface • Volcano-tectonic variability along segments of the Mid-Atlantic Ridge between Azores platform and Hayes fracture zone: evidence from submersible and high-resolution sidescan sonar data • A seismic inversion study of the axial magma chamber reflector beneath the East Pacific Rise near 10oN • Fault-controlled magma transport through the mantle lithosphere at slow-spreading ridges • Structure, petrology and seafloor spreading tectonics of the Kizildag Ophiolite, Turkey • Is the oceanic Moho a serpentinization front? • Tracing the evolution of hydrothermal fluids in the upper oceanic crust: Sr-isotopic constraints from DSDP/ODP Holes 504B and 896A • Petrological investigations of low temperature hydrothermal alteration of the upper crust, Juan de Fuca Ridge, ODP Leg 168 • The structure and controls on fluid-rock interactions in ocean ridge hydrothermal systems: constraints from the Troodos ophiolite • Rare earth element mobility in a mineralized alteration pipe within the Troodos ophiolite, Cyprus • Drilling of sediment-hosted massive sulphide deposits at the Middle Valley and Escanaba Trough spreading centres: ODP Leg 169 • Precipitation of hydrothermal sediments on the active TAG mound: implications for ochre formation • Significance of modern and ancient oceanic Mn-rich hydrothermal sediments,exemplified by Jurassic Mn-cherts from Southern Greece • Ancient vent chimney structures in the Silurian massive sulphides of the Urals • The fossil record of hydrothermal vent communities • Relics and antiquity revisited in the modern vent fauna • Index
