英文摘要	The major rock-forming minerals are same in both barren and mineralized alkaline granites at the baerzhe deposit, mainly composed of microcline, quartz, riebeckite and albite. however, their relative contents and grain sizes are obviously different, as well as the compositions of fluid inclusions and the crystal habits of zircon also show significant differences in these two types of granites. the data on petrology, petrochemistry and element geochemistry suggest that the mineralized alkaline granite is not formed by means of the silicification and albitization of barren alkaline granite. the data also confirmed that these two types of granites are products of crystallization from a same magmatic system at different positions belonging different evolutional stages. and the characteristics on petrology, inclusions and geochemistry show that the highly evolved a-type granitic melt has stepped into magmatic-hydrothermal transition stage. the extraordinary enrichment and mineralization of rare and rare earth elements are closely related to the highly evolved a-type granite in the baerzhe deposit.
