The felsic rock mass always enrich Cu，Mo，W，Sn，Nb，Ta ，then become an rare and non-ferrous metals deposit.Most of these rock masses are small（area＜10 km2）. High SiO2， K2O， K2O/Na2O are benefit of enriching Mo in the magma which rock mass enriches Cu， Mo；high Al2O3， Fe2O3T， MgO， CaO are benefit of enriching Cu in the magma which rock mass enriches Cu，Mo.High SiO2， K2O are benefit of enriching W in the magma which rock mass enriches W， Sn；high Al2O3， Fe2O3T， MgO， CaO are benefit of enriching Sn in the magma which rock mass enriches W，Sn.High Fe2O3T， alkali，TiO2 and low P2O5 are benefit of enriching in the magma which rock mass enrich Nb， Ta. The enriching Cu of rock mass is S type granite，but the enriching Mo of rock mass is transiting from I type to S type granite；the enriching W， Sn of rock mass is S type granite； the enriching Nb， Ta of rock mass has A type， I type and S type granites.
