Notes on the Geochemical Survey in Zamboanga Del Norte - Misamis Occidental, Mindanao, Philippines

摘要

Stream sediment and panned heavy mineral surveys were conducted in Zamboanga del Norte and Misamis Occidental provinces in northwestern Mindanao. A total of 70 stream sediments and 64 panned heavy mineral concentrates were obtained along active streams draining into the Mindanao sea. The minus 80 mesh sediment fractions were analyzed for total uranium using delayed neutron activation analysis techniques. Results indicated that uranium values ranged from 0.3 ppm to 2.4 ppm and 0.1 ppm to 1.1 ppm, for the stream sediments and heavy minerals respectively. These values were considered to be the range of the average concentrations present in the volcanic and marine sediments found in other parts of the country. (Atomindex citation 16:045336)
