Taowan conglomerate ; seismism ; early cambrian period ; luonan shaanxi 陶湾砾岩地震作用早寒武纪陕西洛南

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 震浊积岩分布于洛河韧性剪切构造带之南，属传统"陶湾砾岩"范围和涵义，即为狭义陶湾砾岩而广义陶湾砾岩包括分布于洛河韧性剪切构造带之北的震积岩海啸岩及狭义陶湾砾岩。陕西洛南地区首次发现的震积岩海啸岩震浊积岩震火山岩正常背景沉积地震沉积序列之完整在所报导古地震作用沉积序列当中实属罕见，为华北地块南缘造山过程及深入了解古地震作用提供了良好地段和有力证据。
