Radiogenic heat production in granitoids from the Sierras de Córdoba, Argentina

Abstract One of the most important processes heat generation from Earth's interior is radioactive decay isotopes. The main hosts major radiogenic elements U, Th and K in crust are granitoids. Sierras de Córdoba formed dissimilar granitic intrusions emplaced by a series magmatic events that occurred during Paleozoic. different granitoids classified as A-type, I-type, S-type, there also expression corresponding to Famatinian period which exhibits TTG-type characteristics. In this work, geochemical concentrations making up were compiled single database. production was evaluated, first study area. showed variability for events, with highest values found Achalian magmatism early Carboniferous magmatism, represented A-type Capilla del Monte pluton has rate, value 4.54 ± 1.38 µW/m 3 . lowest S-type granitoids, all belong event. range event goes 0.26 0.05 San Agustin 1.19 0.50 La Playa pluton. An empirical ternary model presented involves K, production, distinction petrogenetic types according S-I-A-M classification. thermal manifestations located on could be related intrusion, involving both neotectonic activity area production. results provide new opportunities studying temperature variation within some these evaluate geothermal potential Córdoba.
