  1. Heat production per element and total radiogenic heat production rate (A) of the Sierras de Córdoba granitoids and their standard deviation. Contributions of U, Th and K to the heat production
  2. *Number of samples analyzed for the determination of mean values. Anomalous heat production values are excluded in the determination of the means. From all the samples in the database (N = 183), anomalous values of Bt-Ap-rich bodies from the Achala batholith, anomalous values of two samples from Sierra Norte, and samples of the Paso del Carmen tonalite and the Agua de Ramón pluton (because there was only one sample of each) were excluded
