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...
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)....
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...
Understanding the dynamics of deep-sea hydrothermal plumes and depositional pattern particles is essential for tracking submarine venting site, prospecting polymetallic sulfide resources, as well deciphering biogeochemistry cycling marine elements. In this paper, a numerical model plume established based on topography long-term current monitoring data Wocan-1 field (WHF-1), Carlsberg Ridge, Northwest Indian Ocean. The allows reconstruction in terms its structure, velocity field, temperature...

摘要: 热液管状蠕虫生物矿化现象在海底热液喷口区发育广泛,但蠕虫管道矿化和风化氧化过程及其控制因素知之甚少.对采自东太平洋海隆热液蠕虫矿化管道样品开展了高分辨率矿物学和元素分布研究.结果表明,样品具有以胶状黄铁矿为主的多圈层矿化结构,分为快速(F型)和慢速矿化(S型)两种类型.相比"S型"样品,"F型"的管壁更厚,同心层的数量少、间隙小、厚度均一.这主要受矿物沉淀速率的影响,即矿物的快速沉淀加快了蠕虫管道生长和矿化.此外,"F型"样品外壁分布的草莓状黄铁矿,表明纳‒微米晶硫化物矿物的定向生长是形成胶状黄铁矿带的重要中间途径.而"S型"管壁从内到外具有氧化程度逐渐增加、胶状黄铁矿逐渐减薄的显著特征,指示样品同时受到了后期低温、富Fe-Si热液流体和低温海水风化氧化作用的影响.本项研究为理解现代海底热液系统的管状蠕虫矿化机制提供了新见解. 关键词: 海底热液 / 管状蠕虫 矿物学 管道圈层结构 硫化物矿化 风化氧化
