英文摘要 | Early Palaeozoic tonalite to granodiorite intrusions in northern Kazakhstan are associated with lode gold mineralization and have SHRIMP zircon ages of 457.3 +/- 6.6 Ma (Aksu), 452.9 +/- 5.6 Ma and 447.4 +/- 5A Ma (both Zholymbet). The Stepnyak intrusion contains large xenoliths with an age of 480.6 +/- 5.0 Ma. One early Palaeozoic zircon from. a porphyritic diorite at Stepnyak has a core with a near-concordant Pb-207/Pb-206 age of 3888 +/- 1.5 Ma, whereas other xenocrystic grains are between 983 and 2698 Ma old. The early Archaean age is probably inherited from unexposed basement of the Kokchetav Massif and represents the oldest crustal material so far known from the Asian continent. It appears that the Aksu, Zholimbet and Stepnyak granitoids were emplaced in the late Ordovician in an Andean- or Japan-type continental arc environment on the margin of the Kokchetav Massif. |
