中文摘要:

作为海洋的热水的系统的重要部分,热水在热水的无机的环境现场发泄动物志并且仔细与热水的无机的环境交往。有时,他们能参予现代热水的地点的矿化作用过程。热水发泄动物志,特别地, vestimentiferan 和 polychaete 试管蠕动,偶尔在地质的记录被保存。早矿化作用过程上的学习热水发泄动物志为理解在矿物质和有机体之间的相互作用是重要的,并且另外在热水的环境的地质的石块的形成和保藏机制。在这篇论文,从朱安·德·富卡·理兹收集的 Vestimentiferan Ridgeia piscesae 试管的矿化作用的早阶段被学习。结果证明很多细丝状的微生物在内部墙并且在试管蠕虫的墙的间隙星际的表面上是不均匀的分布式的。在一些情况中,微生物聚集了同样薄的层在或在试管蠕虫的墙上。微生物引起的房间的表面和微生物引起的降级的产品可以在试管蠕虫的早矿化作用起一个重要作用。包含硫和硫小粒的有机物的半透明的薄层通常与矿化作用的更低的度在试管蠕虫的墙上被发现。这些半透明的薄层的降级生产可以在早阶段期间加速试管墙的矿化作用。版本结果证明在试管墙上,象 Fe, P, Ca 和 Si 那样的某元素有选择地从周围的热水的环境被充实。有趣地,有 Fe 的 P, Ca 和 Si covary 满足。因为元素 S 在试管蠕虫的织物由共生微生物从 H2S 的简历氧化发源,当学习试管墙的矿化作用过程时,它能被看作一个简历标记。与矿化作用的不同的度基于试管蠕虫的特征,我们建议试管墙的早矿化作用阶段被微生物引起导致矿化作用和试管墙的降级过程主要控制。

英文摘要:

As an important part of marine hydrothermal system, hydrothermal vent faunas live in hydrothermal inorganic environment and closely interact with hydrothermal inorganic environment. Sometimes, they can participate in the mineralization process of modern hydrothermal site. Hydrothermal vent faunas, particularly vesUmentiferan and polychaete tubeworms, are occasionally preserved in the geological record. Study on the early mineralization process of hydrothermal vent fauna is significant for understanding the interaction between mineral and organism, and also the formation and preservation mechanism of geological fossil in hydrothermal environment. In this paper, the early stage of mineralization of Vestimentiferan Ridgeia piscesae tubes collected from Juan de Fuca Ridge is studied. The results showed that a lot of filamentous microorganisms were unevenly distributed on the surface of internal wall and in the interspace of the wall of tubeworm. In some cases, microorganisms aggregated as thin layers in or on the wall of tubeworm. The surfaces of microbial cells and the products of microbial degradation may play an important role in the early mineralization of tubeworm. Semitransparent thin layers of organic matter containing sulfur and sulfur granules were commonly found on the wall of tubeworm with lower degree of mineralization. The degradation production of these semitransparent thin layers may accelerate the mineralization of tube wall during the early stage. EDS results showed that on the tube walls some chemical elements such as Fe, P, Ca and Si are selectively enriched from ambient hydrothermal environment. Interestingly, P, Ca and Si covary with Fe content. Because element S originated from the bio-oxidation of H2S by symbiotic microorganism in the tissue of tubeworm, it can be considered as a biomarker when studying the mineralization process of tube wall. Based on the characteristics of tubeworms with different degrees of mineralization, we suggested that the early mineralization stage of tube wall was mai
