亚利桑那的地貌特点:南西为盆地和山脉,东北为科罗拉多高原。这些比较年青的特征是由局部垂向和水平构造和隐伏的冲积、火山和沉积矿床来代表的。虽然该州土壤和植物被覆盖很少,但基岩露头还不到10%。在这种情况下本文提出的区域地球物理编图,对确定基底地质构造、露头与深部的岩性分布都是非常有用的。一般来说,磁异常图上的短波长比重力图上相应波长,能更清楚地反映基底特征,但是,磁性资料的解释比较复杂。
Arizona’s topography features: the basin and mountains to the south and the northeast to the Colorado Plateau. These younger features are represented by locally vertically and horizontally constructed and buried alluvial, volcanic and sedimentary deposits. Although there are very few soils and plants in the state, bedrock outcrops are less than 10%. In this case, the regional geophysical mapping proposed in this paper is very useful for determining the geological structure of the basement, the outcrop and the deep lithology distribution. In general, the short wavelengths on the magnetic anomaly map reflect the base features more clearly than the corresponding wavelengths on the gravitational map, but the interpretation of the magnetic data is more complicated.
