| 英文摘要 | Water is essential to the formation of intracontinental granites, but its origin remains elusive. Here we address this scientific problem by analyzing D/H isotopes of apatites, hydrous minerals in Jurassic and Early Cretaceous granites and basalts from eastern North China Craton, where water was previously interpreted as derived from subducting slab. Results reveal extremely low delta D values in pristine Early Cretaceous granitic (-203 parts per thousand to -127 parts per thousand) and basaltic (-197 parts per thousand to -107 parts per thousand) apatites, contrasting with relatively high delta D values (-137 parts per thousand to -47 parts per thousand) in Jurassic granites. Given the depth-dependent D/H isotopic fractionation during slab dehydration and high-water contents in coeval primitive mafic magmas, the Early Cretaceous magma water is attributed to the stagnant slab within the mantle transition zone. Secular change in the depth of water aligns with steepening of subducting Paleo-Pacific plate from Jurassic to Early Cretaceous, demonstrating the potential of apatite H isotopes in tracing water origin in granites and basalts. Extremely light apatite delta D values indicate deep-originated water in intracontinental granites and basalts from the North China Craton, probably from a stagnant slab within the mantle transition zone. |
