“…Enzymes identified in the crab are stable at high temperature, variable pH and presence of elements known as inorganic inhibitors such as Cu 2+ , Fe 2+ , and Co 2+ (Hu et al, 2012). A study by Zeng et al (2018) showed the accumulation of Mn, Hg, and K within the shells of this crab. Bacteria residing in X. testudinatus were investigated using 16S ribosomal RNA gene amplicon pyrosequencing and revealed a dominance of γand ε-Proteobacteria (Yang et al, 2016).…”

Submarine fluids emissions in the form of geothermal vents are widespread in a variety of geological settings ranging from volcanic to tectonically active areas. This overview aims to describe representative examples of submarine vents in shallow-water areas around the globe. The areas described include: Iceland, Azores, Mediterranean Sea (Italy and Greece), Caribbean, Baja California, Japan, Papua, New Zealand, Taiwan. Common and divergent characteristics in terms of origin and geochemistry of the emitted fluids and their impact on the indigenous organisms and the surrounding environment have been identified. In the hottest vents seawater concentration is common as well as some water vapor phase separation. Carbon dioxide is the most common gas often associated with compounds of sulfur and methane. In several vents precipitation of minerals can be identified in the surrounding sediments. The analyses of the microbial communities often revealed putative chemoautotrophs, with Campylobacteria abundantly present at many vents where reduced sulfur compounds are available. The techniques that can be used for the detection and quantification of underwater vents are also described, including geophysical and geochemical tools. Finally, the main geobiological effects due to the presence of the hydrothermal activity and the induced changes in water chemistry are assessed.

“…Previous systematic studies on mineralogy, geochemistry, and isotopes have been carried out in the Okinawa Trough [6][7][8][9][10][11][12][13][14]. According to the existing geological and geophysical investigations, the Okinawa Trough is a back-arc basin, which is characterized by the development of brittle normal faults and frequent intrusion of magma, providing a favorable tectonic and magmatic environment for the development of hydrothermal systems [15].…”

In this study, mineralogical and elemental geochemical characteristics of massive sulfide samples collected from the Jade hydrothermal field, located in the Izena depression in the central graben of the Okinawa Trough, were analyzed by means of optical microscopy, scanning electron microscopy, and electron probe microanalysis (EPMA). The results show that the mineralization in the Jade hydrothermal field can be divided into Zn-Cu-Pb-rich massive sulfides and Zn-Fe-rich massive sulfides. The former is composed of sphalerite, galena, chalcopyrite, pyrite, and anglesite, which is the product of the low-temperature alteration of galena. The latter is mainly composed of sphalerite, pyrite, marcasite, and traces of galena. Cu and Zn in pyrite may exist in the form of microinclusions, while Ag and Pb may exist in pyrite in the form of fine galena inclusions containing Ag. Fe and Cu may enter sphalerite in the form of ion replacement. Zn may enter chalcopyrite in the form of ion replacement. Consistent with the previous understanding, the metal elements in the hydrothermal liquid system in the Jade hydrothermal field mostly migrated as sulfur complexes, and when the hydrothermal fluid mixes with seawater, the physical and chemical conditions of the fluid change, resulting in sulfide mineral precipitation. However, the chemical structure of chalcopyrite is still controversial, which restricts the understanding of the substitution mechanism of trace elements during chalcopyrite precipitation.

“…The andesite samples are collected from the KHF at the southernmost part of the Okinawa Trough (SPOT), west Pacific (Figure 1). The KHF is a shallow-water hydrothermal field with >30 fluid vents at a water depth of 10-30 m in the southeast of the Kueishantao islet off the Ilan Plain [17][18][19][20][21][22]. The Kueishantao islet is located at a volcanic belt and is characterized by an andesite seafloor with lava and pyroclastics [21,23], located approximately just 100 km above the Wadati-Benioff zone; the continental crust (CC) remains intact (approximately 30 km thick) in the SPOT [24].…”

The studies of iron (Fe), copper (Cu), and zinc (Zn) isotopic compositions in seafloor andesites are helpful in understanding the metal stable isotope fractionation during magma evolution. Here, the Fe, Cu, and Zn isotopic compositions of andesites from the Kueishantao hydrothermal field (KHF) off northeastern Taiwan, west Pacific, have been studied. The majority of δ56Fe values (+0.02‰ to +0.11‰) in the KHF andesites are consistent with those of MORBs (mid-ocean ridge basalts). This suggests that the Fe in the KHF andesites is mainly from a MORB-type mantle. The Fe-Cu-Zn isotopic compositions (δ56Fe +0.22‰, δ65Cu +0.16‰ to +0.64‰, and δ66Zn +0.29‰ to +0.71‰) of the KHF andesites, which are significantly different from those of the MORBs and the continental crust (CC), have a relatively wide range of Cu and Zn isotopic compositions. This is most likely to be a result of the entrainment of the sedimentary carbonate-derived components into an andesitic magma. The recycled altered rocks (higher δ56Fe, lower δ66Zn) could preferentially incorporate isotopically light Fe and heavy Zn into the magma, resulting in relative enrichment of the lighter Fe and heavier Zn isotopes in the andesites. The majority of the δ56Fe values in the KHF andesites are higher than those of the sediments and the local CC and lower than those of the subducted altered rocks, while the reverse is true for δ66Zn, suggesting that the subseafloor sediments and CC materials (lower δ56Fe, higher δ66Zn) contaminating the rising andesitic magma could preferentially incorporate isotopically heavy Fe and light Zn into the magma, resulting in relative enrichment of the heavier Fe and lighter Zn isotopes in the andesites. Thus, the characteristics of the Fe and Zn isotopes in back-arc and island-arc volcanic rocks may also be influenced by the CC and plate subduction components.
