Rapid growth of mineral deposits at artificial seafloor hydrothermal vents
Seafloor massive sulphide deposits are potential resources for base and precious metals (Cu-Pb-Zn ± Ag ± Au), but difficulties in estimating precise reserves and assessing environmental impacts hinder exploration and commercial mining. Here, we report petrological and geochemical properties of sulphide chimneys less than 2 years old that formed where scientific boreholes vented hydrothermal flu...

متن کاملAncient hydrothermal seafloor deposits in Eridania basin on Mars
The Eridania region in the southern highlands of Mars once contained a vast inland sea with a volume of water greater than that of all other Martian lakes combined. Here we show that the most ancient materials within Eridania are thick (>400 m), massive (not bedded), mottled deposits containing saponite, talc-saponite, Fe-rich mica (for example, glauconite-nontronite), Fe- and Mg-serpentine, Mg...
متن کاملCommunity structure of mussel beds at deep-sea hydrothermal vents
Definition of biogeographic provinces, patterns of species distributions on local and regional scales, species richness, and relative abundances are all basic ecological measures, yet they are largely unknown for deep-sea hydrothermal vent ecosystems. Without an appreciation of biogeographic and biodiversity patterns, it is difficult to understand the evolutionary and ecological processes that ...
متن کاملMineralization of Alvinella polychaete tubes at hydrothermal vents
Alvinellid polychaete worms form multilayered organic tubes in the hottest and most rapidly growing areas of deep-sea hydrothermal vent chimneys. Over short periods of time, these tubes can become entirely mineralized within this environment. Documenting the nature of this process in terms of the stages of mineralization, as well as the mineral textures and end products that result, is essentia...
