台湾的锆石和独居石在1903年发现于基隆河.曾在新竹县马武督发现大晶的锆石,后在全省各河道及海滨的砂中也都发现了锆石和独居石,基隆的锆石和独居石混杂在重砂中.近年来,在台湾大陆架发现的锆石含量占重矿物的16.7~26%,含钍矿物和独居石的含量占重矿物的10%左右.最近还在嘉义至台南海滨发现储量达五万多吨的独居石矿床. Taiwan’s zircons and monazite were found on the Keelung River in 1903. Zircons and monazite were found in Maqu Duo, Hsinchu County, and zircons and monazites were found in various river courses and beach sand in the province. Keelung’s Zircons and monazite are mixed in heavy sand.In recent years, the zircons found in the Taiwan continental shelf account for 16.7-26% of the heavy minerals, and thorium-bearing minerals and monazite accounts for about 10% of the heavy minerals.Recently, To Tainan beach found reserves of more than 50,000 tons of monazite deposit.
