| dc.description.abstract | In this work we analyze crustal characteristics of Claromeco intermontane basin using gravity and magnetic anomalies, and local geoid undulations. They are: i) isostatic compensation (based on Airy hypothesis), related to stretching; ii) old sediments filling the basin, covering more than 12 km, with a density contrast value of -100 kg m (super -3) , resulting to be well balanced by an antiroot filled with upper mantle materials. A crustal model is proposed justifying both observed Bouguer anomalies and local geoid undulations. A chart of isobath contours is built using a quadratic equation involving sediments' thickness and local geoid undulation. Magnetic basement depth Z T and Curie point depth Z B are obtained using spectral analysis on a total field magnetic anomaly chart. Results show that Z T reaches a maximum value of 12 km, whereas Z B attains a minimum value below the Claromeco basin. The basin puts aside two different depth domains of the Curie isothermal surface: at the southwestern zone of the Ventania ranges Z B is about 25 km, while northeast of these mountains Z B is about 30 km. | es |
