In the meantime , it indicates , based on available resolution seismic data , that faults with throw of 2 ~ 5 m can be interpreted by applying new technologies of interpretation , processing and display .

这种沿走向变化的地层叠置和横穿MCT的变质等级表明，逆冲断层的断距向西减小，可能是由于地壳短缩总量沿着喜马拉雅造山带向西减小所致。

This along-strike change in stratigraphic juxtaposition and metamorphic grade across the MCT indicates a westward decrease in its slip magnitude , possibly a result of a westward decrease in total crustal shortening along the Himalayan orogen .

中更新世（0.73Ma以来）断裂带又变成略带右行走滑的逆断层，走滑断距不足100m。

Since the Middle Pleistocene ( 0.73 Ma - ), the zone turned to reverse faulting with a slight dextral strike-slip ( less than 100 m ) . Therefore , the Tancheng Lujiang fault zone is an important inversion tectonics situating in eastern Asia .
