【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。
[Abstract]:The Symposium on "Multi-Genetic soft sediment deformation structures and Seismic Rocks" was held on September 24, 2016, during the 14th National Conference on Palaeogeography and sedimentology, hosted by Henan University of Technology in Jiaozuo, Henan Province. A number of domestic experts attended the seminar to discuss and contend on the deformation structure, seismic rock and seismosedimentary rock of soft sediments. This was a very successful seminar, the main outcome of which was the "multigenetic soft sediment deformation structure", which has been accepted by many geologists as the definition of "seismic rock" proposed by Seilachern Sailachern (1969). That is, "rock with fault-grain sequence can be classified as seismic rock" and should be abandoned. However, the definition of seismic rock, which is now accepted by many geologists, that is, "seismic rock is a rock with soft sediment deformation structure really caused by earthquakes" should not be abandoned. The term "seismic rock" should be strictly limited to the strata with deformation structure of soft sediment caused by earthquake.) "seismoclase" is a misinterpreted term and should not be used any more. If some geologists want to continue to use the term, they should redefine the term and indicate that it is not the Chinese translation of "seismites".) the clastic injector is also polygenetic, and it is not necessarily seismic rock. The most important result of this symposium is that the situation of "almost one viewpoint" in the study of deformation structures and seismic rocks of soft sediments in China is beginning to be reversed. Showing the academic atmosphere of "a hundred flowers blossom and a hundred schools of thought contend".
