Abstract

We present determinations of fundamental parameters and lithium abundances of 10 G dwarfs. The analysis of our data shows that the maximum lithium abundance decreasess with decreasingT eff , but with a large scatter. One of the sample stars shows a high lithium abundance as much as 2.34 dex. The correlation between the lithium abundance and absolute visual magnitude or stellar age, does not seem very good. The scatter cannot be uniquely attributed to different initial compositions or to pure age effect.
