对芬兰前寒武纪岩石黑云母中的铵含量进行了测量,以确定黑云母中的铵作为一种化学化石的可能性。在前寒武纪沉积环境中,如果有生物活动的话,那么沉积岩中黑云母的 NH_4~+就应当比火成岩中的黑云母所含 NH_4~+多得多。由约2400—1900Ma 前的沉积作用产物形成的斯
The ammonium content of Precambrian rock biotite in Finland was measured to determine the possibility of ammonium as a chemical fossil in biotite. In the pre-Cambrian sedimentary environment, if there is biological activity, then the biotite in the sedimentary rocks NH 4 + should be much more than the igneous rock in the igneous rock contains NH 4 +. The formation of sediments from about 2400-1900Ma before the sediment
