The TAG hydrothermal field is a site of major active and inactive volcanic-hosted mineralization in the rift valley slow-spreading Mid-Atlantic Ridge at 26[degree]N. axial high principal locus present magmatic intrusions. contains three main areas past activity: (1) an actively venting high-temperature sulfide mound; (2) two former vent areas; (3) zone low-temperature precipitation Fe Mn oxide deposits. volcanic centers occur intersections between ridge axis-parallel normal faults projected...

There is increasing interest in mining minerals on the seabed, including seafloor massive sulfide deposits that form at hydrothermal vents. The International Seabed Authority currently drafting a Mining Code, environmental regulations, for polymetallic sulfides and other mineral exploitation seabed area beyond national jurisdictions. This paper summarizes 1) ecological vulnerability of active vent ecosystems aspects this remain subject to conjecture, 2) evidence limited resource opportunity...
Abstract Microbathymetry data, in situ observations, and sampling along the 13°20′N oceanic core complexes (OCCs) reveal mechanisms of detachment fault denudation at seafloor, links between tectonic extension mass wasting, expose nature corrugations, ubiquitous OCCs. In initial stages faulting high‐angle fault, scarps show extensive wasting that reduces their slope. Flexural rotation further lowers scarp slope, hinders resulting morphologically complex chaotic terrain breakaway denuded...
The distribution of trace ore elements in different paragenetic stages pyrite has been documented for the first time sub-seafloor actively-forming TAG massive sulfide deposit. Trace element distributions have determined by in-situ laser ablation inductively-coupled plasma mass spectrometry (LA-ICP-MS) formed at mineralization, and temperatures constrained previously published fluid inclusion analyses. data reveal a strong dependence on stage, with distinct low- high-temperature enrichments....

Abstract Es wird dargelegt, daß man mit dem Diisocyanat‐polyadditionsverfahren neuartige hochelastische Stoffe von bemerkenswerten Eigenschaften erhält, wenn lineare Polyester aus aliphatischen Dicarbonsäuren und Glykolen einem Überschuß spezieller „sperriger”︁ Diisocyanate in Gegenwart wenig Wasser umsetzt. Die endständig bifunktionellen reagieren zunächst Diisocyanat unter Kettenverlängerung. Vernetzung kommt über die Isocyanat‐Gruppen entstehenden Harnstoff‐Gruppierungen zustande,...
The effect of volcanic activity on submarine hydrothermal systems has been well documented along fast‐ and intermediate‐spreading centers but not from slow‐spreading ridges. Indeed, eruptions are expected to be rare axes. Here we report the presence venting associated with extremely fresh lava flows at an elevated, apparently magmatically robust segment center southern Mid‐Atlantic Ridge near 5°S. Three high‐temperature vent fields have recognized so far over a strike length less than 2 km...
Abstract During opening of a new ocean, magma intrudes into the surrounding sedimentary basins. Heat provided by intrusions matures host rock, creating metamorphic aureoles potentially releasing large amounts hydrocarbons. These hydrocarbons may migrate to seafloor in hydrothermal vent complexes sufficient volumes trigger global warming, e.g., during Paleocene-Eocene Thermal Maximum (PETM). Mound structures at top buried observed seismic data off Norway were previously interpreted as...
Deep-sea mineral deposits potentially represent vast metal resources that could make a major contribution to future global raw material supply. Increasing demand for these metals, many of which are required enable low-carbon and high-technology society relieve pressure on land-based resources, may result in deep sea mining within the next decade. Seafloor massive sulphide (SMS) deposits, containing abundant copper, zinc, gold silver, have been subject recent ongoing commercial interest....
