In land areas with highvelocity rock outcrops,the seismic data recorded by vertical geophone deviate from the data of reflected compression wave with the increment of dip angle of strata and incident angle of reflection wave,which results in the difficulties of conventional seismic exploration in the near-surface high-velocity rock outcropped areas.

结果表明，当近地表速度为低速时，可以将垂直检波器记录的地震记录近似等同于反射纵波记录，这就是常规地震勘探在低速带区勘探取得成功的原因之一；当近地表速度为高速时，随着界面倾角和入射角的增加，垂直检波器记录的地震记录等效为反射纵波记录的误差增大，这就是存在高速近地表区地震勘探的难点之一。

Based on the early geologic studies, more integrated strata units and frame was established in Yunnan and Guizhou. The characteristic of macroscopical lithofacies and paleogeography was also raveled basically in this area. It was ascertained that some perfect developed PTB sections from marine via paralic to terrestrial facies lie in western Guizhou and eastern Yunnan. What's more, the stratigraphic sequence of Marine PTB or Terrestrial PTB across the PTB in this area is similar to that of the Meishan Section.

通过早期地质研究，在我国云南、贵州地区基本建立了比较完整的地层单位与格架，也基本弄清了该区的宏观岩相古地理特征，明确了黔西滇东地区存在发育完整的从海相—海、陆交互相—陆相的二叠系—三叠系界线剖面，而且该区海、陆相界线地层序列与浙江长兴煤山全球界线层型剖面具有一定的相似特征，使得在该区开展陆相二叠系—三叠系界线剖面的高精度划分和海、陆界线地层的高精度对比均成为可能。

According to this scheme, the Longmaxi Formation is only referred to as the black siliceous and carbonaceous shales at the base of the Silurian strata. All the carbonate rocks above it have been redelineated and redivided into new lithostratigraphic units.
