| Abstract: | After the deposition of Triassic Leikoupo Formation in Y area,northeast of Sichuan,the area was uplifted because of the Triassic impact of Indo-I movement,and missed upper and middle parts of the Triassic,and formed a regional parallel unconformity with the overlying Triassic Xujiahe Formation.The weathering of this area provided good condition for the formation of paleokarst.This paper studies comprehensively the weathering crust karst based on the analysis of 8 wells drilling data and log data,the cores a... |
| Keywords: | Northeast of Sichuan Leikoupo Formation paleokarst identification mark |
