AbstractSingle crystal in situ Sr and Nd isotopic analysis of apatite permits more accurate interrogation of a variety of geoscience questions, including provenance, petrogenesis, and ore system evolution. However, the degree to which the apatite Sr and Nd isotopic systems remain closed under extended low-temperature hydrous conditions is not well constrained. Granitoids at the Baogutu deposit in NW China contain veins of low-temperature H2O-rich epistilbite and thus provide an excellent opportunity to evaluate isotopic system integrity under low-temperature hydrous conditions. Apatite from the Late Carboniferous diorite and granodiorite porphyry show variable (Sr-87/Sr-86)(i) ratios (0.7042 to 0.7062) but restricted epsilon Nd(t) values (+7.0 +/- 0.4 and +6.5 +/- 0.4, 1 sigma). The apatite Sr isotope signatures are transitional between whole rock (0.7035) and vein epistilbite (similar to 0.7062), indicating apparent incorporation of radiogenic Sr from the epistilbite-related hydrothermal fluid into the igneous apatite, whereas epsilon Nd values closely match those of the whole rock (+6.9 +/- 0.2 and +6.5 +/- 0.2, 1 sigma) and epistilbite (+6.2 +/- 0.2, 1 sigma). Obvious metasomatic textures of apatite were revealed by cathodoluminescence images. The 260 to 300 degrees C formation temperatures for earlier quartz-sulfide veins and chlorite alteration and homogenization temperature (similar to 190 degrees C) of fluid inclusions in epistilbite-calcite vein calcite constrain the temperature of the later epistilbite-related hydrothermal fluid to 190 to 260 degrees C. These results indicate that Sr and likely Nd isotopes in apatite are mobile under low-temperature (<300 degrees C) hydrous conditions and implies that Rb-Sr signatures in apatite from hydrothermally altered rocks reveal the presence and characteristics of modifying fluids.
