| Abstract: | On the basis of field investigation, large scale(1:50000) geologically mapping, Quaternary age determination, and by use of structural analytic method, we have analysised and compreheserded the basic structural type of the Liangyun fault, structural deformation sequence and dispersed strike slip(pull apart)pattern basin, concentrated pressure shear pattern bend and its relative structures. Quaternary slip rate of the middle western segment of the Liangyun fault is quantitavely estimated. |
| Keywords: | Liangyun fault geologically mapping structural analysis Quaternary slip rate structural deformation |
