摘要

摘要: 报道了冲绳海槽伊平屋海洼海底黑烟囱样品中保留完好的矿化微生物群,它们的形态完好。主要有四种不同类型的丝状体,这些丝状体可能是硫或者铁氧化化能自养细菌和真菌矿化而成。对这些微生物矿化过程的研究表明,它们主要经过了两个阶段的矿化:(1)生物控制矿化阶段;(2)生物诱导矿化阶段。早期以生物控制矿化为主,晚期以生物诱导矿化为主。形成的矿物与热液成分以及微生物种类有关。

Abstract: Large amounts of microfossil records have been discovered in the seafloor black smoker chimney from the Okinawa Trough. They preserve good shapes,many of which can be divided into four kinds of filamentous microfossils. It suggested that the fossils may be derived from sulfur or iron oxidation chemolithotrophic prokar yotes and fungi. Two steps of biomineralization were hypot hesized based on the comparison studies of the microbial mineralization processes:(1)biology-controlled mineralization;(2)biology-induced mineralization. At the earlier stage the biology-controlled mineralization is as a main process,at the later stage biomineralizalion is dominated by the biology-induced mineralization.The composition of the fluids and the species of the microbes will decide the types of the minerals formed.
