前寒武纪沉积铁矿的成因,是地质界长期争论的一个问题.《化石》杂志一九七六年第一期刊登了一篇题为“铁细菌与富铁矿”的文章,通过介绍铁细菌与沉积铁矿的关系,说明铁矿的一种生物成因论,现摘其要点转介如下.科学工作者通过对某些新生铁矿的研究,发现它们多半不是由水体中简单的化学作用形成的,而是生活在沼泽湖泊中的铁细菌生物化学作用的产物.这种铁细菌是单细胞生物,没有形成细胞核,直径只有几到几十微米.它的外面包裹着一层薄薄的“铁甲”
The genesis of Precambrian sedimentary iron mines is a long-standing controversy in the geology field.Fossil magazine published an article entitled “Iron bacteria and iron-rich ore” in the first issue in 1976, By describing the relationship between iron bacteria and sedimentary iron ores, a biogenic theory of iron ore is presented, the main points of which are summarized as follows: Scientists, through the study of some new-born iron ores, find that most of them are not caused by the simple , But rather the product of the biochemical effect of iron bacteria living in marsh lakes, which are single-celled organisms that do not form nuclei and are only a few to tens of microns in diameter and are surrounded by a layer of Thin “armor ”
