通过野外调查在甘肃陇南的文县阳山金矿东北磨坝—观音坝一带首次发现一大套震碎砾岩,这套砾岩由于覆盖在白垩纪红色砾岩之下,故而一直把其当作白垩纪砾岩处理。通过作者参加该项目的研究后认为,是一套震碎角砾岩,这种震碎角砾岩,在国内外尚未见公开报道。它是地质历史上一次浅源强烈地震的岩石记录,反映了该地区一次重要的地震构造运动,同时本文对该地区的震积岩进行了沉积序列及岩石类型划分,这种观点对促进陕甘川地震历史的认知有重要的补充作用。
Through field investigation, for the first time, a large quarry conglomerate was found in the northwestern margin of the Mudba-Guanyinba, Yangshan Gold Mine, Wen County, Longnan, Gansu. This conglomerate, which covered the Cretaceous red conglomerate for the first time, Cretaceous conglomerate processing. After the author participated in the study of the project, he thought that it was a set of shattering breccias that have not been reported openly at home and abroad. It is a rock record of a shallow intense earthquake in the geological history, reflecting an important earthquake tectonic movement in this area. At the same time, the sedimentary sequence and rock types of seismites in this area are divided. The cognition of the earthquake history has an important complementary role.
