A successful symposium of "Multi-origin of soft-sediment deformation structures and seismites"

The symposium was successfully held in September 24,2016 at Henan Polytechnic University,Jiaozuo,Henan Province,China. Many geologists in China attended this symposium,and they enthusiatically discussed the problem of soft-sediment deformation structures(SSDS),seismites etc. the products of this symposium are as follows:(1) The terms "SSDS" and "Multi-origin of SSDS" were accepted by numerous geologists.(2) The definition of seismites by Seilacher(1969),i.e.,"fault-graded beds interpreted as seismites",should be obsoleted,however,the definition by many geologists today,i.e.,"the seismites are the beds with SSDS really induced by earthquakes",should not be obsoleted and should be retained.(3) The term "seismites" should be strictly restricted to the beds with SSDS that are really induced by earthquakes.(4)"Zhenjiyan" is a mistranslated term of "seismites" andshould not be uesd any more. If some geologists would like to use the term of "Zhenjiyan" in the future,they should define it again and point out that it
