利用地球化学指标研究沉积古地理环境的方法,得到了沉积岩工作者和地球化学工作者的重视。近年来,国外文献中有较多的报导。我们在泥炭调查工作中,也进行了这方面的探索。感到有几种指标,如锶(Sr)钡(Ba)比、硼(B)锂(Li)比、黄铁矿中二价铁和有机炭的比等,对于研究相环境有一定的意义。下面仅对用锶、钡(以下写作Sr、Ba)比研究现代泥炭沉积环境的方法谈一些看法。同时,将近年来测定的各个时代地层的Sr、Ba比指标归纳于后,以供同志们在今后工作中参考。
Using geochemical indicators to study the methods of sedimentary paleo-geography has attracted the attention of sedimentary rock workers and geochemical workers. In recent years, there are more reports in foreign literature. We have also carried out exploration in this area in the peat investigation work. Feel that there are several indicators such as the ratio of barium (Ba) to barium (Ba), the ratio of lithium (Li) to boron (B), the ratio of ferrous and organic carbons in pyrite, which is of some significance for the study of the phase environment. The following is only a few comments on the methods used to study modern peat depositional environments with strontium and barium (hereinafter Sr, Ba). At the same time, the Sr and Ba ratios of various age strata measured in recent years are summarized in the future for the reference of comrades in future work.
