Uranium hydrogeochemical and stream sediment reconnaissance of the Aztec NTMS quadrangle, New Mexico

Technical Report ·
OSTI ID:6407425
A total of 338 water and 1744 sediment samples were collected from 1876 locations over a 20 200-km/sup 2/ area at a nominal density of one location per 10 km/sup 2/. Water samples were collected from wells, springs, streams, and artificial ponds. Sediment samples were collected from springs, streams, and artificial ponds. The uranium concentrations in waters range from below the detection limit of 0.2 ppB to 67.3 ppB. The mean uranium concentration for all water types is 2.68 ppB. Only one small cluster of three water samples containing anomalous uranium concentrations is noted. These samples, collected about 50 km north of Cuba, were taken from drainages that cut the San Jose formation. Several individual water samples with anomalous uranium concentrations are associated with fault zones. Sediments have uranium concentrations that range between 0.3 ppM and 30 ppM, with a mean concentration of 4.23 ppM. The majority of anomalous sediment samples were collected from area underlain by either the Nacimiento or San Jose formation in the San Juan basin. Just northwest of Cuba a small cluster of sediment samples with anomalous uranium concentrations occurs surrounded by several known uranium deposits. 10 figures, 4 tables.
