− | Tectonic maps of a basin and surrounding areas, in combination with regional structure [[cross section]]s, give an overall impression of the geologic architecture of the basin and form the base from which other interpretations are made. A large-scale map shows the depth to the [[basement]] in the basin and the distribution of crustal types. Always be sure important tectonic elements are shown, such as specific fold belts and major faults. | + | Tectonic maps of a basin and surrounding areas, in combination with regional structure [[cross section]]s, give an overall impression of the geologic architecture of the basin and form the base from which other interpretations are made.
