| Abstract: | The extreme-high peak of sharp-knife form, in Jr curve is named, by the writer, the "transgfression sword", which indicates the transgression and the existing of marine deposits usually. Being found frequently in coal-bering formation, the "stage regression" andthe "vibration regression" are both typical style-regression benificial to the coal-accumulated. |
