U-Pb and 40Ar/39Ar geochronology of the coastal Sonora batholith: New insights on Laramide continental arc magmatism
Ramos-Velázquez,Ernesto - Calmus,Thierry - Valencia,Victor - Iriondo,Alexander - Valencia-Moreno,Martín - Bellon,Hervé

Formato:	journal article
Enlaces:	The coastal Sonora batholith comprises a series of Cretaceous granitoids that intruded a metasedimentary basement of possible Mesozoic age. They are partially covered by Tertiary volcanic flows and pyroclastic rocks. In order to elucidate the crystallization and cooling history of…

U-Pb geochronology of granitoids in the north-western boundary of the Xolapa Terrane
Valencia,Victor A. - Ducea,Mihai - Talavera-Mendoza,Oscar - Gehrels,George - Ruiz,Joaquin - Shoemaker,Sarah

Formato:	journal article
Enlaces:	The Sierra Madre del Sur, a Mesozoic-Cenozoic magmatic arc in southern Mexico, was studied using U-Pb zircon geochronology. Undeformed to slightly deformed plutons from two transects were sampled at the limit between the Guerrero and Xolapa terranes, in order to…
