| Abstract: |
| Understanding deeply the interrelationship between different kinds of gravity current deposits is an extremely important subject in the study of lake sedimentology.Recently the transporting process models for turbidity currents with diverse origin have been established through the analysis and anatomies of resedimentation by disaster events. A tremendous debris flow emptying directly into Lucerne Lake occurred at Wegiss Town in 1795. The research of sedimentation caused by this event reveals the characteristics of transportation and sedimentation for different facies of subaqueous mud flow, providing a good case for the transforming process from mud flow into turbidity currents. |
