摘要
本文作者首次较详细报导贵州织金洞滴石类堆积物中含有大量的藻类微体生物化石。并对其形态、结构进行了手标本、显微镜、扫描电镜的观察和研究,对其种属也进行了初步鉴决,结果表明,藻类具有明显的生长线和迭层构造,其生长受洞穴内外各种环境。尤其是气候环境的控制和制约,同时也是环境的直接反映。这一发现进一步揭示和丰富了洞穴堆积物成因理论,预计在第四纪环境预报方面将会起一定的作用。笔者较系统的研究洞穴滴石类堆积物中藻类生物的建造作用在国内外也属首次。
The writers first discover and report that the dripstone in Zhijing Cave contins a lot of microbiological and algal fossils. The shapes and structures of them have been observed and studied by naked eyes, microscopes and sweeping electronic microscopes. Their biologic species are preliminary identified. The results show that those algal have obvious growing lines and stromatolithic structures. Their goowing is strictly controled by various environments both inside and outside the cave, especially by the climatic environment, and in turn they directly reflect the environmental changes. The discovery would greatly enrich the theory of cave dripstone formation. It would play an important role in foretelling the climatic changes of the Quaternary period. Microbiogical and algal formation in dripstones of caves are systemetically studied, which may be first at home and abroad.
