对工业地震测线的解释表明，加州湾北方的东部边缘包含不活跃的Adair-Tepoca和Upper Tiburon盆地。西部边缘是活跃的，包括瓦格纳，康萨格，上德尔芬和下德尔芬盆地。这些盆地系统被一个宽的基底隆起所分隔，不活动盆地的上部地层与活动盆地的中下部地层相对应，记录了上新世晚期应变和沉降向西迁移的过程。我们的研究结果说明形成一个废弃的裂谷边缘沿着东部的加州湾。
Interpretation of industry seismic lines indicates that the eastern margin of the northern Gulf of California contains the inactive Adair-Tepoca and Upper Tiburon basins. The western margin is active and includes the Wagner, Consag, Upper Delfin, and Lower Delfin basins. These basin systems are separated by a wide basement high across which the upper strata in the inactive basins correspond to the middle and lower strata in the active basins, recording the westward migration of strain and subsidence during late Pliocene time. Our results illustrate the formation of an abandoned rift margin along the eastern Gulf of California.
