Seismite is a petrological record of seism event in geologic history. From the bottom to top, the seismite sequence is composed of microfault bed, rubble bed and homogeneous bed. As a peleo-seisometer. The seismite can be used to understand seismicity and migrating laws of seism in geologic history.As a living example of seismite the authors discovered in Emei Mountain, authors have described various characteristics and summarized the marks of seismites.

震积岩(物)是地史时期地震事件的岩石学记录,其震积层序自下而上由微型递变断裂层、微褶皱层、碎块层和液化均一层组成。震积岩可作为古地震计,以了解地史时期地震的时空分布、地震强度和迁移规律。以作者发现的峨眉震积岩为例,描述了震积层序中的各种特征,总结了认识和辨别震积岩的标志。

Seismit is the petrological record of seismic event in geological history. It is characterized by the seismitic structure. To identify the seismits are very important for the research on the development history of seism, regional tectonic, basin analyse and stratigraphic correlation.This paper, based on the Emei Mountain seismit which was found by the writers, discribed the characteristics of the seismit and seismitic structure, and summerized the differences of the seismitic structure with the other confusable...

震积岩是地质历史中地震事件的岩石学记录,具有特征的震积构造.识别震积岩,对于研究地震历史、区域构造发展史和进行盆地分析、地层对比等,都具有重要意义.本文以作者等所发现的峨眉震积岩为基础,描述了震积岩和震积构造的特征,总结了震积构造与滑塌构造、冰缘构造、沙丘塌落和流沙构造、巷曲层理等易混淆构造的区别。

This paper briefly demonstrates that the muscovite(two-mica) granite is a petrological record of intracontinental subduction.The indosininn-Yanshanian (245-122Ma) two-mica granites are widely distributed in the Sonth China Continent and the Tianshui-Yajiang region,and the foreland fold-belts are developed on both sides of the Yangtze Continent.Such a symmetric feature and their structural setting indicate the intracontinental subduction of Yangtze Continent beneath both the South China Continent and the Songpan-Ganzi...

This paper briefly demonstrates that the muscovite(two-mica) granite is a petrological record of intracontinental subduction.The indosininn-Yanshanian (245-122Ma) two-mica granites are widely distributed in the Sonth China Continent and the Tianshui-Yajiang region,and the foreland fold-belts are developed on both sides of the Yangtze Continent.Such a symmetric feature and their structural setting indicate the intracontinental subduction of Yangtze Continent beneath both the South China Continent and the Songpan-Ganzi fold belt.Based on both the total width of two-mica granite zones on both sides of the Yangtze Continent (about 650km ), the minimum subducted width of Yangtze continent is estimated to be 650km. The present width of Yangtze continent is about 680km, therefore the Yangtze Continent is reduced at least to about one half of its original width by the Mesozoic intracontinental subduction. Alternatively, the subducted area may be a micro-continent situated between the Yangtze Continent and Jiangnan orogenic belt. This paper gives a criterion to recognize and distinguish the intracontinental subduction zone and the thrust tectonic zone. The tectonic boundary between the Yangtze Continent and Qinling orogenic belt is a thrust-strike slip tectonic zone rather than a intracontinental subduction zone.The "Jiangnan orogonic belt" and Longmenshan "orogenic belt"are believed to be the overriding continents, rather than to belong to the Yangtze Continent. The inner side of the Mesozoic Southeast orogenic zone is considered to belong to the Hisgher Himalays-type intracontinental subduction zone rather than to the Yarlu Zangbo-(Tsangpo-) type or the Hsu's(1987) collision orogenic zone-type. The intracontinental subduction is believed to be the main mechanism for the formation of the South China Continent,which underwent both of the Neoproterozoic and the Caledonian intracontinental subduction events resembling the Yarlu Zangbo-type or the Hsu's (1987) collision orogenic zone type. Both the multiple intracontinental subduction and formation of muscovite granites with consequent concentration of the metallic elements of continental crust affinity may be a favouruble dynamic background for the formation of the large and superlarge W-Sn-Sb-Nb-Ta-REE-U ore deposits in the South China Continent.

本文简要地论述了白云母（二云母）花岗岩是陆内俯冲的岩石学记录。华南大陆与天水－雅江地带广泛分布中生代王云母花岗岩侵作入体，已有的同位素年龄范围为２４５～１２２Ｍａ，与此同时，它们两侧的扬子大陆发育前陆褶皱带，这种成对性及其构造配置表明，扬子大陆曾向华南大陆与松潘—甘孜褶皱带发生过陆内俯冲作用。基于二云母花岗岩带的总宽度（约６５０ｋｍ），估算扬子大陆最小的总俯冲量（指宽度）至少为６５０ｋｍ，扬子大陆现今宽度约６８０ｋｍ，这样，扬子大陆在中生代时期由于陆内俯冲作用缩小了约一半；另一可能方案是，消失的主要是夹持于扬子大陆与江南造山带之间的一个微大陆。扬子大陆与秦岭造山带之间的壳内构造边界不具陆内俯冲性质，而是逆冲推复一走滑构造带。在大地构造单元上，江南造山带与龙门山造山带应分属两个上叠大陆，而不属于扬子大陆。华南中生代造山带内侧属于高喜马拉雅型陆内俯冲带（缝合带内无蛇绿岩伴生），而不是雅鲁藏布江型（缝合带内有蛇绿岩伴生）。陆内俯冲作用是华南大陆形成的主要机制之一。此外，它经受过晚元古代和加里东期陆内俯冲事件，可能属于雅鲁藏布江型。多次陆内俯冲和白云母（二云母）花岗岩的形成导致亲陆壳金属元素富集，可能是华...
