Abstract

Phosphorites from the Pechenga Basin, with an age of 2.04 Ga, were produced by microorganisms. Phosphorites of the Pechenga Greenstone Belt were found in the form of numerous rounded, slightly deformed fragments (Fig. 1). The earliest Early Proterozoic (Pechenga) phosphorites show all the characteristics of a cyanobacterial mat—a prokaryotic benthic community united in a physical structure by the glycocalyx.

第 6 章科拉半岛早新生代磷酸盐岩科拉半岛早新生代磷酸盐岩

摘要年龄为 2.04 Ga 的佩钦嘎盆地磷酸盐岩是由微生物产生的。佩成雅绿岩带的磷酸盐岩以大量圆形、轻微变形的碎片形式被发现（图 1）。最早的早新生代（佩成阿）磷酸盐岩显示了蓝藻垫的所有特征--蓝藻垫是一种由糖萼结合成物理结构的原核底栖生物群落。
