Abstract:
The table presents the 143Nd/144Nd ratios measured from fossil fish teeth at ODP Site 198-1208, together with corresponding sample identifiers, depths, and ages. These ratios were converted to εNd values using a chondritic reference of 143Nd/144Nd = 0.512638. All analyses were conducted using MC-ICP-MS at the State Key Laboratory of Marine Geology, Tongji University.
