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.

震積巖(物)是地史時期地震事件的巖石學記錄,其震積層序自下而上由微型遞變斷裂層、微褶皺層、碎塊層和液化均一層組成。震積巖可作為古地震計,以了解地史時期地震的時空分布、地震強度和遷移規(guī)律。以作者發(fā)現(xiàn)的峨眉震積巖為例,描述了震積層序中的各種特征,總結了認識和辨別震積巖的標志。

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.

本文簡要地論述了白云母（二云母）花崗巖是陸內(nèi)俯沖的巖石學記錄。華南大陸與天水－雅江地帶廣泛分布中生代王云母花崗巖侵作入體，已有的同位素年齡范圍為２４５～１２２Ｍａ，與此同時，它們兩側的揚子大陸發(fā)育前陸褶皺帶，這種成對性及其構造配置表明，揚子大陸曾向華南大陸與松潘—甘孜褶皺帶發(fā)生過陸內(nèi)俯沖作用。基于二云母花崗巖帶的總寬度（約６５０ｋｍ），估算揚子大陸最小的總俯沖量（指寬度）至少為６５０ｋｍ，揚子大陸現(xiàn)今寬度約６８０ｋｍ，這樣，揚子大陸在中生代時期由于陸內(nèi)俯沖作用縮小了約一半；另一可能方案是，消失的主要是夾持于揚子大陸與江南造山帶之間的一個微大陸。揚子大陸與秦嶺造山帶之間的殼內(nèi)構造邊界不具陸內(nèi)俯沖性質(zhì)，而是逆沖推復一走滑構造帶。在大地構造單元上，江南造山帶與龍門山造山帶應分屬兩個上疊大陸，而不屬于揚子大陸。華南中生代造山帶內(nèi)側屬于高喜馬拉雅型陸內(nèi)俯沖帶（縫合帶內(nèi)無蛇綠巖伴生），而不是雅魯藏布江型（縫合帶內(nèi)有蛇綠巖伴生）。陸內(nèi)俯沖作用是華南大陸形成的主要機制之一。此外，它經(jīng)受過晚元古代和加里東期陸內(nèi)俯沖事件，可能屬于雅魯藏布江型。多次陸內(nèi)俯沖和白云母（二云母）花崗巖的形成導致親陸殼金屬元素富集，可能是華...
