Abstract: Seismites are referred to as sedimentary sequences which were deposited due to the working of the unconsolidated submarine sediments by seismic activity in the tectonic active area. When investigating the geologic profiles of the East Yellow River coalfield, the authors discovered for the first time seismites in the Carboniferous coal-bearing strata. which may be subdivided from the bottom to the top into fault zone, microfolded zone and homogeneous bed. The study of the rocks will contribute to:(1)the understanding of the distribution and periodicity of ancient seismic activity and characteristics of palaeotectonic movements;(2)the supplement of the new content to seismic geology, stratigraphy and event sedimentology, and(3)the providing of information about plate movement.
