Modern Geodata Management: Application of Interdisciplinary Interpretation and Visualization in Central America

Figure 10

Looking from southeast, we draped the geological map of Figure 8 (bottom) onto the Bouguer gravity map (Free-Air anomaly offshore and Bouguer anomaly onshore, Figure 9). This combination provides interesting insight into the “geological” masses that cause the anomalies of the gravity field. For example, the ophiolite of the Nicoya complex, forming the Nicoya Peninsula (NP), is located in the area of the uplifted gravity field map. The active volcanic belt, for example, Irazú (IR) and Arenal (AR), in this figure is clearly located in a minimum of the Bouguer gravity field, which points to low densities in the upper crust.
