seismism n.【地質學;地理學】地震(現象)。

seismo-

Taowan conglomerate was formed with underwater seismism at early cambrian period and consists of shattering sedimentary rock , tsunami rock , seismic turbidite and seismic volcanic rock . the shattering sedimentary rock consists of folded rock , cracked rock and autobreccia . the seismic turbidite is located in the south of luonan ductile shear zone and is called the narrow taowan conglomerate . contrarily the broad taowan conglomerate consists of shattering sedimentary rock , tsunami rock located in the north of the zone . the seismic sequence of shattering sedimentary rock - tsunami rock - seismic turbidite - seismic volcanic rock - normal sedimentary rock was first found in luonan shanxi and is rare among the reported examples about it , so it is a good example and offers power evidences to study how the southern marginal basin of huabei plate transferred to qinling orogenic belt 震濁積巖分布于洛河韌性剪切構造帶之南,屬傳統“陶灣礫巖“范圍和涵義,即為狹義陶灣礫巖而廣義陶灣礫巖包括分布于洛河韌性剪切構造帶之北的震積巖海嘯巖及狹義陶灣礫巖。陜西洛南地區首次發現的震積巖海嘯巖震濁積巖震火山巖正常背景沉積地震沉積序列之完整在所報導古地震作用沉積序列當中實屬罕見,為華北地塊南緣造山過程及深入了解古地震作用提供了良好地段和有力證據。
