在大青山地区进行综合水文地质调查中,曾见到大青山地層有与前人调查资料不同之处,即第三紀的干诺霸玄武岩与红土層之间的问题。前人资料中,认为第三紀的最底部是干诺霸玄武岩,在干诺霸玄武岩之上有红土層沉積,但这次在大青山东南部朱海西窪于北20°东一公里处大冲溝所见到的天然剖面如下图。恰与前人资料相反。冲溝的底部为红土層沉積并已膠結,
During the comprehensive hydrogeological survey in the Daqingshan area, there were some discrepancies between the Daqingshan strata and the survey data of the predecessors, namely, the problem between the Norbar basalt and the lateritic strata in the Tertiary. According to the previous data, the bottom of the Tertiary is that of the Noroban basalt, which has a red soil sediment on the top of the Noroban basalt, but this time it is large in the east of the Zhuhai Sag at the southeast of Daqingshan, 20 km east of the kilometer The natural profile seen by the gully is shown below. Just the opposite of the previous data. The bottom of the gully is a layer of red clay that has been cemented and cemented.
