对Paradox盆地的地表断裂进行了制图，以识别构造活动及其对地下地层学的影响。对阿巴霍地堑和洛哈特盆地地区的断层进行了详细的地面制图，并与盐背斜带和针叶断裂带的断层进行了表面特征对比。阿巴霍地堑地区和洛克哈特盆地的断层位移小于盐背斜带的断层，并且表现为1 ~ 30英尺宽的剪切带，而不是单断层束缚底辟盐背斜。这一对比表明，悖论盆地西南部的构造复杂性低于其他地区。在阿巴洛地堑和洛克哈特盆地地区，断裂通常为方解石胶结或矿化，而针叶带的断裂则为开放或冲积裂缝，这表明这两个构造区在地下水运动或形成年龄上存在差异。
Surface faults of the Paradox Basin were mapped to identify tectonic activity and its effect on subsurface stratigraphy. Faults mapped in the Abajo Grabens and Lockhart Basin areas Were mapped on the groundin detail, and their surface characteristics were compared with faults in the salt anticline belt and the Needles fault zone. Faults in the Abajo Grabens area and Lockhart Basin have smaller displacements than the faults in the salt anticline belt, and are expressed as shear zones 1 to 30 feet wide rather than as single faults bounding the diapiric salt anticlines. This comparison suggests that there is less structural complexity in the southwestern part of the Paradox Basin than elsewhere. Faults in the Abalo Grabens and Lockhart Basin area are commonly cemented or mineralized with calcite, but those in the Needles zone are open or alluvial-filled fractures, suggesting a difference in ground-water movement or age of formation between these two structural areas.
