displays a primary thick-banded structure with δ34SV-CDT values in the range of 14.5‰-14.8‰. Combined with the 87Sr/86Sr values (0.707737-0.707783) of limestone, it can be suggested that the Sanhedong... (0.707695-0.708629) and δ34SV-CDT values (9.6‰-17‰), thus indicating a marine source but with the input of continental materials. The initial layered salt formations were formed by chemical deposition in a basin......

. The microstructure analysis of joint reveals that the microstructures of the various regions are very different, and the microstructure distribution is layered and wide on the mechanical heat-affected zone. When the process parameters are not appropriate, the oxide and impurity congregate between the layered microstructures. The existence of the impure stratum structure and stress concentration......
