| 摘 要： | 本文在峨眉地裂运动理论的启示下,于川中内江—合川一带的二叠系中发现地震反射异常点9处,成排分布在北东向4排构造带上。它们可能是生物礁群、台块边缘岩性变化或小断层的反映,是川中寻找天然气的一个新领域,值得进一步勘探。

| Abstract: | Nine abnormal spots of reflecting seismic information have been revealed in Lower Permian strata from Neijang to Hechuan in Central Sichuan in the light of the concept of Emei Taphrogenesis. They are distributed in rows in four NE-trending anticlinal zones and could be the reflection of grouped reefs, or lithologic change on the rim of platform block, or even some small faults. They probably suggest some new field for gas exploration and worth further prospecting. |
