text: The least-altered apatites show similar (or slightly enriched) initial 87Sr/86Sr ratios (0.7080–0.7108) and εNd(t) values (-4.0 to -1.8), whereas the hydrothermally altered apatites are characterized by significantly higher initial 87Sr/86Sr ratios (0.7091–0.7119) and more negative εNd(t) values (-4.9 to -4.4), probably due to the interaction between the hydrothermal fluids and wall rocks.
