Thermobarometry and Thermochronology: Applications to the Study of the La Caridad and Suaqui Verde Porphyry Copper Deposits

Classically, porphyry-type copper deposits are considered to form between 2 and 4 km depth. However, in the Basin and Range province, some of them, as the La Caridad and Suaqui Verde deposits, have been preserved in the footwall of normal faults. This study addresses this paradox by taking the afore...

However, in the Basin and Range province, some of them, as the La Caridad and Suaqui Verde deposits, have been preserved in the footwall of normal faults. This study addresses this paradox by taking the aforementioned deposits as an example by combining thermobarometry and thermochronology analyses to quantify the emplacement depth and cooling history of the plutons, respectively. The results suggest that the emplacement depth of the porphyry copper could be greater than 4 km. In addition, they show that eastern Sonora did not experience a clear increase in exhumation rate during the Basin and Range extension, which may explain the good preservation of Cretaceous-Eocene deposits in this region. Clásicamente, se considera que los depósitos de tipo pórfidos de cobre se forman entre 2 y 4 km de profundidad. Sin embargo, en la provincia Basin and Range, algunos pórfidos de cobre como los de La Caridad y Suaqui Verde permanecieron preservados en el bloque de piso de fallas normales. Este trabajo propone un estudio comparativo de estos dos depósitos, combinando análisis de termobarometría y de termocronología para cuantificar la profundidad de emplazamiento y la historia de enfriamiento de los plutones, respectivamente. Los resultados sugieren que la profundidad de emplazamiento de los pórfidos de cobre podría ser superior a 4 km. Además, muestran que el este de Sonora no registró un aumento significativo de la tasa de exhumación durante la extensión Basin and Range, lo que puede explicar la buena preservación de los depósitos del Cretácico-Eoceno en esta región.
