根据拉曼激光分子微探针的分析，在格陵兰岛西南部Isua系列的石英岩的燧石层中检测到的细胞状包裹体由生物物质组成。现有的放射性测量数据将该序列的年龄确定在3，800百万年左右。我们的标本的薄切片是在岩石基质中的主要位置拍摄的。所用的材料是致密的，未风化的。没有采用可能产生人工制品的浸渍、蚀刻、浸渍或其他方法。
CELL-like inclusions detected in the cherty layers of a quartzite, which is part of the Isua series in South-west Greenland, consist of biological materials, according to analyses by Raman laser molecular microprobe. The available radiometric data place the age of the sequence at around 3,800 Myr1. Thin sections of our specimens were taken in their primary positions within the rock matrix. The material used was compact and unweathered. No maceration, etching, impregnation or other methods were applied which might have produced artefacts.
