摘要
随着现代海底热液生物群研究工作的深入,开展地质历史时期的古热液生物群研究的必要性也日益凸现。近年来古热液生物群研究已取得一定的进展,结合前人的工作,总结了所发现的古热液生物群的时空分布、产出地质背景、化石壳体保存特征、化石组合特征等内容。简述了开展古热液生物群研究工作的一般方法有:描述法、比较法与地球化学方法。最后,从现代热液生物群研究意义的角度出发,讨论了古热液生物群研究在生物起源、热液活动和板块构造、环境治理以及生物成矿等方面的重要意义,并提出当前古热液生物群研究存在的问题及今后的工作重点。
With the development of the research of modern hydrothermal vent community, some have already diverted their views into the research on fossil hydrothermal vent community. The geological era and settings of hydrothermal vents, characters of the fossil hydrothermal vent community and its categories etc. are analyzed based on the materials reported. Some common methods or ways about research of fossil hydrothermal vent community are enumerated, including describing, contrasting and chemical means. The research the fossil hydrothermal vent community possess some significances, especially in studying the origin of life, enriching Bionomics, explaining the plate tectonics, reflecting the hydrothermal activity, improving the environment and researching bio-mineralization. By far, many problems about the fossil hydrothermal vent community have not been solved, including enriching and deepening the contents about hydrothermal vent community, perfecting the ways and means about researching fossil hydrothermal vent community.
