Abstract

Bacterial paleontology studies the roles played by organisms in the genesis of sediments and ores. It is, therefore, important to clearly distinguish in-situ biological objects present in the rock material from various contaminants of later origin and from mineral structures that merely resemble organisms. The same is crucial for correct interpretation of alleged biogenic structures found in meteorites. The use of a scanning electron microscope equipped with an EDX microanalysis system and designation of model objects from previously studied rock samples allows us to address this problem. This approach also needs to be applied to previously discovered structures.

岩石和天文学中的生物污染和矿物伪生物结构。

摘要

细菌古生物学研究生物在沉积物和矿石的成因中所起的作用。因此，重要的是要清楚地区分岩石材料中存在的原位生物物体与后来起源的各种污染物以及仅类似于生物体的矿物结构。对于正确解释在陨石中发现的所谓生物结构，同样至关重要。使用配备有EDX微量分析系统的扫描电子显微镜和指定先前研究过的岩石样品中的模型对象可以使我们解决这个问题。此方法也需要应用于以前发现的结构。
