Thorite is found in the river beds west of the island coexisting with zircon and other minerals as magnetite, hematite, basaltic hornblend, epidote, garnet, hypersthene, staurolite, tourmaline, rutile, etc. The geological origin is not clear. The heavy sand is magnetically concentrated for thorite, hematite, magnetite, and zircon. Chemical analyses of the concentrates are done by four local institutes and the Associated Metals and Minerals Corporation, U.S.A. Total rare earths (including ThO/sub 2/) come to 63.26%, the ThO/sub 2/ from all samples average 4.21 to 6.79%. The zircon contains 65.45% of ZrO/sub 2/, HfO/sub 2/ and the ratio HfO/sub 2//ZrO/sub 2/ = 0.016. Th e estimated total thorite deposit in Formosa is 7,500,000 metric tons of heavy sand containing 4.4% of ThO/ sub 2/. (TTT)
