N2 - Metamict and well crystalline fergusonite-(Y) were treated by U,Th,Pb-rich fluids at temperature 200oC for 60 days. The well crystalline fergusonite did not show any apparent features of alteration. The metamict fergusonite was intensivelly replaced by newly-formed U and Th-rich phases. The TEM study of the FIB prepared foils revealed, that Th-rich phase is amorphous, whereas the U-rich phase corresponds to UNb3O10. On the border of unchanged metamict fergusonite and newly-formed phases the numerous of nanopores were found. The alteration corresponds to dissolution-reaction-precipitation process.
