英文摘要	The Nyainqentanglha granite, a batholith with an area of 1500 km(2) in the central Lhasa block, comprises mainly medium-fine-grained biotite monzonitic granite and medium-coarse-gramed biotite monzonitic granite. Their contact relationship suggests that the medium-fine-grained biotite monzonitic granite was crystallized earlier than the medium-coarse-grained monzonitic granite. A SHRIMP U-Pb dating on zircons from representative samples of the batholith shows that the crystallization age of the medium-fine-grained biotite monzonitic granite is 18.3 Ma and that of the medium-coarse-grained monzonitic granite is 11.01 Ma. The emplacement and crystallization of the Nyainqentanglha granite, the youngest granite batholith ever known inside the Lhasa block, have a close relationship with the collisional orogeny, crustal thickening, plateau uplifting, E-W crustal extension and have a dynamic genetic relationship with the crustal partial melting.
