AbstractThe Xing'an Block is one of several fault-bounded crustal units in northern China located along the southeastern margin of the Central Asian Orogenic Belt (CAOB) and includes the Great Xing'an Range. The basement rocks constitute a khondalitic sequence of sillimanite- and garnet-bearing gneisses, hornblende-plagioclase gneiss and felsic paragneiss named the Xinghuadukou Complex. LA-ICP-MS zircon U-Pb dating of a sillimanite gneiss from Hanjiayuan indicates high-grade metamorphism occurred at 496 ± 3. Ma, with several older detrital zircon grains with ages extending from 678 ± 8 to 1373 ± 17. Ma. A sample of hornblende-plagioclase gneiss from the northern part of the Xinghuadukou Complex yields a metamorphic age of 496 ± 7. Ma, whereas igneous zircon core ages range from 601 ± 15 to 1637 ± 23. Ma. Another sample of hornblende-plagioclase gneiss from farther south in the Xinghuadukou Complex yields a metamorphic age of 495 ± 5. Ma, and magmatic core ages of 546 ± 4. Ma. These data indicate that high-grade metamorphism occurred at ~. 500. Ma and that several earlier magmatic events are recorded in the area, including some in the Neoproterozoic. These new age data, together with other recent data obtained from the Erguna, Songliao, Jiamusi and Khanka blocks, establish a > 1300. km Pan-African khondalite belt along the southern margin of the CAOB. © 2011 Elsevier B.V.
