贵卅南部泥盆系中下部发育着一套石英砂岩——蟒山石英砂岩(乐森(王寻),1929)。以往用传统地层学理论强行将其与时间地层单位统一,造成划分对比上的混乱。本文用多重地层划分的概念,对蟒山石英砂岩的穿时性作了讨论,并用古地质图等分析了穿时机制。重新确定了岩石地层单位—蟒山石英砂岩的定义。
A set of quartz sandstone - python quartz sandstone is developed in the middle and lower part of the southern Devonian in Guijue (Lesen (Wang Xun), 1929). In the past with the traditional theory of stratigraphy forcibly unites with the time stratigraphy, resulting in confusion on the division of contrast. In this paper, the concept of multiple stratigraphic division is used to discuss the timeliness of the python quartz sandstone. The paleogeological map is used to analyze the wear mechanism. Redefinition of the rock formation unit - Mangshan quartz sandstone definition.
