英文摘要The Paleozoic granites in the Ergun block, exposed in the northeastern Da Hinggan Mts., northeastern China, are of Itype. Zircon U-Pb dating by LA-lCPMS technique indicates that the Shibazhan, Neihe and Baiyinna plutons were emplaced with ages of 499 +/- 1, 500 +/- 1 and 460 +/- 1 Ma; whereas the Chalabanhe pluton was formed by several pulses with age between 465 similar to 481 Ma. Considering other previously reported age data, it is proposed that the granitic magmatism in the northeastern Da Hinggan Mts. during the Early Paleozoic took place at 460 similar to 500Ma. Zircon Hf analyses conducted by LA-MC-ICPMS show that these granites have epsilon(Hf) ( 0 values of + 1. 5 similar to + 3. 8 with Hf modal ages of 1.1 similar to 1.4Ga, indicating that the crust in the Ergun block was extracted from mantle during Meso-Ncoproterozoic, which is much different from the Xinglan block to the south, in that it shows a characterized Phanerozoic crustal age.
