Lacustrine Slope-Related Soft-Sediment Deformation Structures in the Cretaceous Gyeokpori Formation, Buan Area, SW Korea, and Volcanism-Induced Seismic Shocks as Their Possible Trigger

The Gyeokpori Formation in the Buan volcanic area primarily contains siliciclastic rocks interbedded with volcanoclastics. These sediments are characterized by a variety of soft-sediment deformation structures (SSDS). SSDS embedded poorly sorted conglomerates; slump folds also present formation. mechanisms and triggers causing not yet clear. In study, trigger was investigated using facies analysis. This included evaluation reworking process both cohesive non-cohesive sediments. analysis indicates that directly or indirectly associated alternation conglomerates mud layers clasts. underwent deformation, respectively, which promoted were controlled extent experienced sediment slope environment. style morphology differ, particularly case activity. study contributes to understanding lacustrine slope-related structures.
