英文摘要The multi-stage diagenesis and mineralization of granitic pegmatite type rare metal deposits is a focused issue in the genetic research of pegmatite type deposits. The North Tugeman lithium-beryllium deposit is a newly discovered rare metal deposit in the middle Altyn area. Some pegmatite dikes preserved complex zonation and developed multi.stage diagenesis and mineralization phenomenon. A combined study towards the introduction of multi.stage diagenesis and mineralization in the North Tugeman lithium beryllium pegmatite basing on the LA-ICP-MS dating of zircon and coltan from the cassiterite-spodumene-bearing breccia muscovite albite granite (20AE43-3)in rho 31 pegmatite dike,the finely crystalline granite (ZK8702-79-3)in rho 87 pegmatite dike,the coltan. bearing finely crystalline granite (20TC8701-1-1)and the coltan-bearing muscovite pegmatite (20TC8701-1-2)in TC87 exploratory trench was carried out. The results indicate that:1)the rho 31 cassiterite-spodumene-bearing breccia muscovite albite granite has a concordant U.Pb age of 436. 0 +/- 1. 1Ma of zircon;2)the rho 87 finely crystalline granite has a concordant U-Pb age of 415. 4 +/- 1. 5Ma of zircon;3)the rho 87 coltan-bearing finely crystalline granite has a U.Pb age of 434. 6 +/- 2. 8Ma of coltan and coltan-bearing muscovite pegmatite has a U-Pb age of 414. 7 +/- 3. 0Ma of coltan. Integrated with the published test and analysis results,we propose that there are three stages of diagenesis and mineralization in the North Tugeman lithium.beryllium deposit:468 similar to 454Ma,436 similar to 434. 6Ma,and 415. 4 similar to 414. 7Ma. It is suggested that the three stages of lithium.beryllium granite-pegmatite diagenesis and mineralization are correspondent to the post-collision extension stage of the Central Altyn and the South Altyn blocks,the collision stage of the North Altyn and the Central Altyn blocks,and the post-collision extension stage of the Altyn and the East Kunlun blocks,respectively
