Abstract

The Orgueil meteorite was studied using a TESCAN VEGA 3 scanning electron microscope. As a result, new microfossils were found, including a fragment of a pennate diatom shell, tubular structures with double porous cell walls (prasinophytes?), hollow spheres with a process (acritarchs?), and spore-like structures. The problem of the cometary origin of the Orgueil meteorite is discussed.

Orgueil陨石中微化石的新发现

摘要

使用TESCAN VEGA 3扫描电子显微镜研究了Orgueil陨石。结果，发现了新的微化石，包括一个半球形硅藻壳的碎片，具有双多孔细胞壁的管状结构（prasinophytes？），带有突起的空心球（acritarchs？）以及类似孢子的结构。讨论了Orgueil陨石的彗星起源问题。
