摘要
"多成因的软沉积物变形构造及地震岩"专题研讨会,2016年9月24日在河南焦作河南理工大学承办的第14届全国古地理学及沉积学学术会议期间召开。国内多位专家出席这次研讨会,对软沉积物变形构造、地震岩、震积岩等问题进行讨论和争鸣。这是一次十分成功的研讨会,其主要成果是:(1)"多成因的软沉积物变形构造"已为广大地质学家接受。(2)赛拉赫(Seilacher,1969)提出的"地震岩"(seismites)的定义,即"具断层—粒序的岩层可定为地震岩",应该废弃;但现在为广大地质学家所接受的地震岩的定义,即"地震岩是真正由地震引起的具软沉积物变形构造的岩层",则不应废弃,可以保留下来。(3)"地震岩"这个术语应严格地限制在真正由地震引起的具软沉积物变形构造的岩层。(4)"震积岩"是一个误译的术语,不宜继续使用。如果有的地质学家想继续使用这个术语,应对这个术语重新定义,并指明它不是"seismites"(地震岩)的中文译名。(5)碎屑注入体也是多成因的,它不一定是地震岩,更不一定是"原地地震"的标志。(6)本次研讨会的最重要的成果是中国软沉积物变形构造及地震岩研究中的"几乎是一个观点"的局面开始被扭转过来了,呈现出了"百花齐放和百家争鸣"的学术气氛。
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＂（震积岩）is a mistranslated term of＂seismites＂and should 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 is not the Chinese translation of the term of ＂seismites＂. （5）The clastic injections are also with multi-origin,and they cannot definitely be the seismites and may not be the exact criteria of in-situ earthquakes. （6）The most important product of this symposium is that the phenomenon of almost one viewpoint of the researches of SSDS and seismites in China has been changed eventually.
