英文摘要	There are abundant late Mesozoic volcanic rocks in Tahe, north Da Hinggan Mountain. The main rock types of these volcanic rocks are basalt,basaltic andesite basaltic trachyandesite and traehyandesite and the alkalic ones are dominant. They have a SiO(2) range of 47. 34% - 58.03% and their K(2)O contents change between 1.25% and 3.44%. These rocks are all enriched in LILE such as Rb and Ba with delta Eu changes from 0.71 to 1.14. HFSE such as Nb and Ta have a conspicuous trough in the primitive mantle normalized spider diagram. From the isotopes point, ((87) Sr/(86) Sr) (i) has a range of 0.705472 to 0.707821 and epsilon(Nd) ( 0 changes from - 6.81 to 0.58, which are near the EMI area and have a trend to EMII area. As for lead isotopes, (206) Pb/(204) Ph is 18.1497 to 18.5394, (207) Pb/(204) Ph is 15. 4886 to 15. 5390, (208) Pb/'(204) Pb is 37.7608 to 38.3441, which are between EMI and EMII areas and also have a trend to EMII area. Judging from the above characteristics of the Tahe Mesozoic volcanic rocks and other people's studies, we conclude that this suit of late Mesozoic volcanic rocks in Tahe originated from the remelting and fractionation of metasomatized enriched subcontinental lithospheric mantle.
