| 摘 要： | 采用光学显微镜以及扫描电镜对冲绳海槽海底黑烟囱样品进行研究,发现了大量的微生物化石,它们保留了完好的形态,主要有四种不同类型的丝状体,可能是硫或者铁氧化化能自养细菌和真菌。这些化石微生物的鉴别基于大小、形状、细胞分裂、群落聚集等物理标志。初步研究表明这些微生物不仅依存于海底热液活动,同时在热液成矿过程中起着重要的作用。

| Abstract: | By light microscopy and scanning electron micrography, abundant microfossils have been found in the seafloor black smoke from Okinawa Trough. They preserve good shapes, mainly including four filamentous types. Based on size, shape, cell division, distribution in colonies of microfossils, we infer that the fossils may be sulfur or iron oxidation chemolithotrophic prokaryotes and fungi. The study shows that such microorganisms not only depend on marine hydrothermal activity, but also plays an important role in mineralization. |
