A record of uranium-series transport at Nopal I, Sierra Peña Blanca, Mexico: Implications for natural uranium deposits and radioactive waste repositories

Abstract: Studies of uranium-series (U-series) disequilibria within and around ore deposits provide valuable information on the extent and timing of actinide mobility, via mineral-fluid interaction, over a range of spatial and temporal scales. Such information is useful in studies of analogs of high-level nuclear-waste repositories, as well as for mining and mineral extraction sites, locations of previous nuclear weapons testing, and legacy nuclear waste contamination. In this study we present isotope dilution mass spec… Show more

“…Samples of iron oxide-oxyhydroxide fracture fillings were collected from the PB1 drill core to extend the uranium-series investigations into three dimensions. Long-lived Useries results for the surface fracture-filling materials have been summarized and compared to new U-series analyses of the drill-core fracture-filling materials by Denton et al (2016). High uranium concentrations in the fracture-fill materials of about 12 to 7700 ppm (Denton et al, 2016, Table 2) indicate uranium mobility and transport from the ore deposit in the past.…”

“…Long-lived Useries results for the surface fracture-filling materials have been summarized and compared to new U-series analyses of the drill-core fracture-filling materials by Denton et al (2016). High uranium concentrations in the fracture-fill materials of about 12 to 7700 ppm (Denton et al, 2016, Table 2) indicate uranium mobility and transport from the ore deposit in the past. Uranium concentrations generally decrease with horizontal distance away from the ore deposit.…”

“…Descripción de las principales características de las muestras la Tabla 9 se presenta la información geoquímica del área de estudio donde cabe destacar que no se incluyó al U debido a que este se encontró por debajo de los límites de detección (< 1 ppm). Una posible explicación a esto puede deberse a que, según Denton et al (2016)[218], en el área de estudio las concentraciones más altas de U se encuentran…”
