Located in western Australia, Darling Range is rich in lateritetype bauxite resources. In order to understand metallogenesis of the lateritetype bauxite in Darling Range and constrain the source of oreforming materials, this study carried out element geochemistry analysis and LA ICPMC dating of detrital zircons from bauxite and underlying granite. The results show that the bauxite in the Darling Range are composed mainly of Al2O3, Fe2O3, SiO2, and TiO2. A12O3 has a negative relationship with SiO2, but a positive relationship with TiO2. It suggests that bauxite experienced the loss of Si and enrichment of Al and Ti during the oreforming process. Geochemical analysis shows that the bauxite is enriched in Th, U, Nb, Ta, Zr, Hf and Ti, and depleted in Ba, K, Sr, P and Sm. The bauxite is characterized by low REE contents from 136 ×10-6 to 6558×10-6, and the chondritenormalized REE pattern slightly tilts to the right and shows enrichment in LREE. LAICPMC detrital zircon UPb ages of the bauxite can be assigned to two groups: 1167~1267 Ma (2 zircons) and 2539~2696 Ma (16 zircons). The former younger detrital zircons possibly came from AlbanyFraser orogeny, while the later older detrital zircons have the weighted average ages of 2579±15 Ma (MSWD=116), consistent with 2585±12 Ma (MSWD=0.83) of Archean granite, with the difference within the error. This indicates that besides the zircons from Archean granite, minor zircons in the lateritetype bauxite may derive from AlbanyFraser orogeny belt. Using Al2O3/TiO2 ratio, lgCrlgNi plot，trace element ratios，and REE pattern to trace the source of lateritetype bauxite deposit, it can be concluded that Archean granite is the major source of oreforming materials for the lateritetype bauxite deposit in the Darling Range of western Australia.
