Palynostratigraphic studies of the Carboniferous strata of the Szczawno and Wałbrzych formations, outcropping in the vicinity of Wałbrzych in the northern part of the Intra-Sudetic Basin, are reported. Rocks of the Szczawno Formation in a section near Konradów had earlier been assigned to the Upper Visean, while rocks of the Wałbrzych Formation in the Biały Kamień section were included to the Lower Namurian [the Stenozonotriletes triangulus–Rotaspora knoxi (TK) Miospore Zone]. This study describes abundant palynological material with many taxonomically diverse miospore assemblages from these rocks, allowing precise palynostratigraphic conclusions. These showed that the rocks of the Szczawno Formation studied should be referred to the lower part of the Serpukhovian [Verrucosisporites morulatus (Vm) Subzone], correlated with the lowest Namurian, while rocks of the Wałbrzych Formation from Biały Kamień belong to the Lower Bashkirian [Lycospora subtriquetra–Cirratriradites rarus (SR) Subzone], correlated with the Upper Namurian A. These results indicate that the rocks from both sections studied are younger than they were earlier believed. This revises the age of the Szczawno and Wałbrzych formations in the northern part of the Intra-Sudetic Basin which belong to four miospore zones, from Vm to SR, corresponding to the Serpukhovian and lowermost Bashkirian (Namurian A corresponding to the Pendleian to Alportian of British chronostratigraphy).

据报道，南水内盆地北部的Szczawno和Wałbrzych地层的石炭纪地层的古地层研究。早在Konradów附近的一段Szczawno组的岩石就被分配给上Visean，而在BiałyKamień段的Wałbrzych组的岩石则被归入Namurian下层[即Stenozonotriletes triangulus – Rotaspora knoxi（TK）Miospore区]。这项研究描述了丰富的古生物学材料，这些岩石具有许多分类学上不同的微孢子组合，从而可以得出精确的古地层学结论。这些表明，所研究的Szczawno组的岩石应指向Serpukhovian的下部[与最低那慕尔人有关的Verrucosisporites morulatus（Vm）分区]，而来自比亚韦·卡米恩的Wałbrzych组岩属于下巴什基尔人[ Lycospora subtriquetra–Cirratriradites rarus（SR）子地区]，与上那慕利人A有关。这些结果表明，研究的两个断面的岩石都比以前认为的年轻。这修改了南体内盆地北部的Szczawno和Wałbrzych地层的年龄，这些地层从Vm到SR属于四个微孢子带，分别对应于Serpukhovian和最低的Bashkirian（Namurian A，对应于Pendleian到Alportian英国）。年代地层学）。
