摘要
本文描述了蠕虫状灰岩中不同类型的同生变形构造，分析了其成因机制，认为蠕虫状灰岩中同生变形构造的形成与其本身重力作用下产生的超孔隙液压有关，表明该灰岩是高能条件下快速堆积的产物。其它证据也说明其形成与风暴作用有关，实际上是一种风暴岩。
In the vertnicular limestone of the Lower triassic in Lower Yangtze area , various contemporaneous deformation structures are well-devoloped. Their occrrence was related to the excess pore pressure in the vermicular limestone at the synsedimentary stage. Yhe above genetic mechanism suggests the vermicular limestone deposited at a high rate under the condition of high energy, and the bottom mold structures, hummocky cross-beddings and other sedi-mentary structures indieate that the sedimentation of this rock was concerned with storm. It is actually tempestite.
