泥炭沉积盆地具有不同于其它沉积盆地的地球化学特性。认识这种沉积盆地内一系列元素的分布规律,对于恢复古地理环境和沉积条件,丰富煤田地质理论均有重要意义。本文以西南地区晚二迭世含煤沉积为例,就泥炭沉积盆地中硫、铁分布特征与沉积环境的关系提出几点初步看法,以期引起讨论。
Peat sedimentary basins have different geochemical characteristics than other sedimentary basins. Understanding the distribution of a series of elements in these sedimentary basins is of great significance for the restoration of palaeogeographic environment and sedimentary conditions and for enriching the coalfield geological theories. In this paper, taking the Late Permian coal-bearing sediments in Southwest China as an example, some preliminary opinions on the relationship between the distribution characteristics of sulfur and iron in the peat sedimentary basin and sedimentary environment are put forward in order to arouse discussion.
