Depth, age, strontium isotopic ratios and trace elemental ratios of samples f...

Please note, that on 2017-06-09 it was discovered that the age values were given as "ka" alhough the values were "Ma". The data are now recalculated (x1000) to fit the unit.

请注意：2017年6月9日经核查发现，原数据的年代数值标注单位为“ka（千年，kilo-annum）”，但实际数值对应的真实单位应为“Ma（百万年，mega-annum）”。目前已将所有数据重新计算（乘以1000）以匹配正确的单位制式。
