摘要：

<正> The granite weathering in Longnan, Jiangxi, is represented by mineralogical changes of feldspars · montmorillonite, illite · kaolinite, halloysite · bauxite, with Na, Ca, Si, P, V, U and Sr being in a mobile state while Ti, Al, Fe, Sc, Th, Zr and Hf remaining relatively conservative. With the exception of Zr/Hf, Nb/Ta, Th/Sc, Zr/Nd and Sm/Nb, changes are notable in ratios between most of the trace elements. Re-distribution of REE and Y has taken
