众所用知,在文献中大量地描述了被称之为硅化的微型有机物,发现于古代沉积中。主要见于美国、澳大利亚、非洲、苏联各地以及其它地区的前寒武纪沉积中。对于显生宙沉积物的硅质微化石则报道较少。通过对硅化藻及其它有机结构的人工硅化试验,获得了和古代微化石极相似的形成物。 It has been widely used in the literature to describe a great deal of what has been called silicified microrganics found in ancient sediments. Mainly seen in the Precambrian sediments in the United States, Australia, Africa, throughout the Soviet Union and elsewhere. Silical microfossils for the Phanerozoic sediments are reported less. By artificial silicidation of silicified algae and other organic structures, a very similar formation to the ancient microfossils was obtained.
