Abstract Aim The pattern of biodiversity and biogeography is crucial to informing management conservation strategy. But a lack study across multiple ridge systems, especially for the Carlsberg Ridge, has hampered conception overall picture Indian Ocean vents, top target deep‐sea exploration massive sulphides. Here, we aim characterize fauna from three new vent fields on Ridge first time, answer 1) what biogeographic within 2) how does this guide future environmental ridges. Location Vents...
The ultramafic-hosted Kairei vent field is located at 25°19′ S, 70°02′ E, towards the Northern end of segment 1 Central Indian Ridge (CIR-S1) a water depth ~2450 m. This study aims to investigate distribution trace elements among sulfide minerals differing textures and examine possible factors controlling element in those using LA-ICP-MS spot line scan analyses. Our results show that there are distinct systematic differences distributions throughout different minerals, as follows: (1) pyrite...
This study explores the spatiotemporal evolution characteristics of mineralogy, geochemistry, and microbial diversity sediment cores near Tianxiu hydrothermal area on Carlsberg Ridge in northwestern Indian Ocean. Our research aims to elucidate variability activity across temporal scales ranging from tens millennia millennia, how spatial variation iron fluxes were deposited. Additionally, we aim investigate authigenic minerals responded these variations.Analysis a distal-vent core retrieved...
The Wocan-1 hydrothermal field is distinct on the occurrence of an active sulfide mound, discovered axial volcanic ridge slow-spreading Carlsberg Ridge. size mound comparable to TAG located in off-axis Mid-Atlantic In order understand its formation and controlling factors, we did geological mapping, mineralogical geochemical analysis precipitates. Our results show ∼ 260 m diameter 50 height. southern area enriched high-temperature Cu-rich sulfides, while northern characterized by...
In this paper, we conduct a comparative study on the mineralogy and geochemistry of metalliferous sediment collected near active hydrothermal site (Wocan-1) inactive (Wocan-2) from Wocan Hydrothermal Field, Carlsberg Ridge (CR), northwest Indian Ocean. We aim to understand spatial variations in primary post-depositional conditions intensity circulations systems. Sediment samples were six stations which includes TVG-07, TVG-08 (Wocan-1), TVG-05, TVG-10 (Wocan-2), TVG-12 TVG-13 (ridge flanks)....
Abstract The Kairei hydrothermal field is located on the Central Indian Ridge at 70°02′E, 25°19'S, which was discovered in 2000. Eight representative product samples including massive sulfide, sulfide chimney and mineralized rock breccia collected from this were age‐dated using 230 Th/ 234 U 210 Pb/Pb methods. Four episodes of activity determined: 94.5 to 96.3 ka (event I), 56.6 61.2 II), 8.4 10.6 III), <180 a present IV). Among them, event I oldest characterized by low‐temperature...
We have studied morphology, mineralogy and geochemical characteristics of Fe-oxyhydroxide deposits from metal-enriched sediments the active (Wocan-1) inactive (Wocan-2) hydrothermal sites (Carlsberg Ridge, Northwest Indian Ocean). on Wocan-1 site are reddish-brownish, amorphous subangular. They occur in association with sulfides (e.g., pyrite, chalcopyrite sphalerite) sulfate minerals gypsum barite). The composition shows enrichment transition metals (Ʃ (Cu + Co Zn Ni) = ~1.19 wt. %) low...
Abstract Hydrothermal activity on mid‐ocean ridges plays an important role in shaping marine chemistry, yet the variability of hydrothermal venting and its forcing mechanism remain elusive. Here, we analyzed a sediment core obtained near tectonic‐controlled Tianxiu vent field, Carlsberg Ridge, to reconstruct history. The documented two significant events (H1 H2) past 30 ka. H1 occurred at 24.1–24.5 ka during Last Glacial Maximum (LGM), while H2 10.5–11.6 deglacial period. Compared H2, was...
