We report the abundance determination in the atmosphere of the bright halo star HD221170 .
The spectra were taken with the Terskol Observatory ’ s 2.0-m telescope with a resolution R=45000 and signal-to-noise ratio up to 250 in the wavelength region 3638-10275 Å .
The adopted atmospheric parameters correspond to an effective temperature T _ { \mathrm { eff } } =4475 K , a surface gravity \mathrm { \log } ~ { } g =1.0 , a microturbulent velocity v _ { \mathrm { micro } } =1.7 { \mathrm { km~ { } s ^ { -1 } } } , and a macroturbulent velocity v _ { \mathrm { macro } } =4 { \mathrm { km~ { } s ^ { -1 } } } .
The abundances of 43 chemical elements were determined with the method of spectrum synthesis .
The large overabundances ( by 1 dex relative to iron ) of elements with Z > 38 are shown to follow the same pattern as the solar r-abundances .
The present HD221170 analysis confirms the non-universality of the r-process , or more exactly the observation that the astrophysical sites hosting the r-process do not always lead to a unique relative abundance distribution for the bulk Ba to Hg elements , the Pb-peak elements , and the actinides .
