New crustal images beneath Long Beach, California show the region of the Inner Borderland to continent transition. The cross-sections are obtained from stacked autocorrelations of virtual sources generated from oil-industry data recorded in the city of Long Beach, CA. They show that the Moho is dipping at 65° and obliquely truncates an ∼10 km thick flat-lying lower crustal fabric. The Moho appears to be fault controlled and an integral part of the extrusion of the Catalina Schist that underlays the Inner Borderland. The basement interface has significant offsets of up to 2 km, none of which correspond to the mapped trace of the Newport–Inglewood Fault.

加利福尼亚长滩下方大陆-边界过渡的详细图像

加利福尼亚长滩下方的新地壳图像显示了内陆边界到大陆的过渡区域。横截面是从加利福尼亚长滩市记录的石油工业数据生成的虚拟源的堆叠自相关中获得的。他们表明，莫霍面倾斜 65°，并斜截断了约 10 公里厚的平躺下地壳结构。莫霍面似乎是断层控制的，是位于内边疆之下的卡塔利娜片岩挤压的一个组成部分。基底界面有高达 2 公里的显着偏移，其中没有一个对应于 Newport-Inglewood 断层的映射轨迹。
