We present stellar parameters of 19 K-type giants and their abundances of 13 chemical elements ( Al , Ba , Ca , Fe , K , Mg , Mn , Na , Ni , Sc , Si , Ti and V ) , selected from two moving groups , covering the metallicity range of -0.6 < [ Fe/H ] < 0.2 , based on high resolution spectra .
Most elemental abundances show similar trends with previous studies except for Al , Na and Ba , which are affected by evolution seriously .
The abundance ratios of [ Na/Mg ] increase smoothly with higher [ Mg/H ] and [ Al/Mg ] decrease slightly with increasing [ Mg/H ] .
[ Mg/Ba ] show distinction between these two moving groups which is mainly induced by chemical evolution and partly by kinematic effects .
The inhomogeneous metallicity of each star from the moving groups demonstrate that these stars have different chemical origins before they were kinematically aggregated and favor the dynamical resonant theory .
