dc.description.abstract"In the eastern portion of the Trans-Mexican Neovolcanic Belt a group maars, rhyolitic domes, and cinder cones are scattered within the Oriental-Serdán basin. They are flanked by large polygenetic volcanoes. We use aeromagnetic and gravimetric fields to infer and model the main anomalies in the region, with the objective of identifying and characterizing the sub-surface sources of the volcanic activity. A large, positive magnetic anomaly overlaps the principal area of volcanic activity; it coincides with the main, positive gravimetric anomaly in the area. Both 2-D and 3-D gravity, as well as magnetic models confirm the existence of a large, dense, and magnetized intrusion body nearly reaching the surface, inferred to be the source of the observed anomalies. The intrusion is flanked to the south by rhyolitic domes. Three independently modeled cross-sections coincide in correlating the presence of maars with upward projections of the main intrusion; these projections we interpret as diatreme-type structures, although the modeling scale does not allow for individual identifications. The conduit that supplied magma for the emplacement of the rhyolitic domes of Las Derrumbadas is also identified to depths of four kilometers. A gravity inversion shows in 3-D space the density distribution at various density ranges."
