同沉积变形造成了加利福尼亚San Joaquin谷西侧复杂的构造和地层关系。对Lost Hills背斜这一实例的研究说明一个简单的构造作用,即断弯褶皱作用为何引起了复杂的生长地层。Lost Hills背斜是一个在Lost Hills逆冲断层上一个断阶引起的断-弯褶皱。该逆冲断层从第三纪底面的下滑脱面沿北东27°方向爬升到Reef Ridge组中上滑脱面。下和上沿脱面分别位于6km和4km处。下滑脱面的位移约6.5km,断弯褶皱作用缩减了2km,余下的4.5km向北东方向延伸到San Joaquin谷之下。褶皱前翼和后翼的倾角分别为42°和2°,与断-弯褶皱理论相符。
The same sedimentary deformation resulted in the complex structural and stratigraphic relations on the western side of San Joaquin Valley, California. A study of the Lost Hills anticline shows a simple tectonic effect of why the action of broken folds caused complex growth formations. The Lost Hills anticline is a fault-fold fold caused by a discontinuity in the Lost Hills thrust. The thrust fault climbed from 27 ° C to the Reef Ridge slip-surface in the Teef Ridge Formation from the falling surface of the Tertiary bottom. The next and the upper edge of the surface were located at 6km and 4km. The displacement of the descending surface is about 6.5km, the effect of breaking and folding is reduced by 2km, and the remaining 4.5km extends to the northeast under the San Joaquin Valley. The inclination of the front wing and the rear wing of the fold is 42 ° and 2 °, respectively, which is consistent with the theory of break-bend fold.
