U-Th ages were calculated using the initial detrital 230Th/232Th value of 111 ± 41 ppm, which was previously calculated for SC02 based on two isochrons measured in separate...
铀钍测年年龄(U-Th ages)通过初始碎屑态钍-230(230Th)与钍-232(232Th)比值为111 ± 41 ppm(parts per million)计算得到,该比值此前针对SC02样品,基于在不同……中测得的两条等时线(isochron)计算得出……
