Soft-sediment deformation structures from an ice-marginal storm–tide interactive system, Permo-Carboniferous Talchir Formation, Talchir Coalbasin, India
چکیده انگلیسی

Permo-Carboniferous Talchir Formation, Talchir Coalbasin, India, records sedimentation during a phase of climatic amelioration in an ice-marginal storm-affected shelf. Evidences of subtidal processes are preserved only under thick mud drapes deposited during waning storm phases. Various soft-sediment deformation structures in some sandstone/siltstone–mudstone interbeds, like syn-sedimentary faults, deformed laminations, sand–silt flows, convolute laminations and various flame structures, suggest liquefaction and fluidization of the beds due to passage of syn-depositional seismic shocks. In the Late Paleozoic ice-marginal shelf, such earthquake tremors could be generated by crustal movements in response to glacioisostatic adjustments of the basin floor.
