dc.description.abstract Tyrrhena Patera is located to the southeast/northeast of the Isidis/Hellas impact basin. It was geologically active into the Late Amazonian, although the main edifice was formed in the Noachian (~3.7-4.0 Ga) [1]. Tyrrhena Patera and the surrounding area contain gravity and magnetic anomalies that appear to be correlated (see Fig. 1). The results presented here are for the anomalies 1a and 1b (closest to Tyrrhena Patera), however other anomalies in this region have been modeled and will be presented at the conference. The Mars Global Surveyor (MGS) free-air gravity signature of Tyrrhena Patera has been studied by [2], who inferred the existence of an extinct magma chamber below it. The magnetic signature has been mapped by [3], who compared electron reflectometer data, analogous to the total magnetic field, for Syrtis Major and Tyrrhena Patera and argued for demagnetization of both volcanoes. en_US
