Uranium Distribution in Northwestern Mindoro Island, Philippines

摘要

Uranium geochemical mapping based on stream sediment (-80 mesh size) employing delayed neutron activation analysis (DNAA) was tried in northwestern Mindoro Island. An automated analysis system was utilized to analyze for uranium by the neutron activation/delayed neutron counting technique. A total of 411 samples were analyzed. These samples were collected at a density of one sample per 2 sq. km. The background and threshold values were 2.4 ppm and 5 ppm uranium, respectively. Isolated anomaly points were delineated over Paleozoic (Carboniferous) Mindoro Metamorphics and Eocene Caaguray Formation. (Atomindex citation 16:045340)
