| 英文摘要 | Based on the U-Pb zircon dating analysis within Tarim basin, it is indicated that there were 9 stages of tectonothermal events of the Precambrian basement with the peak age of 2950 similar to 3100Ma, 2100 similar to 2400Ma, 1900 similar to 2000Ma, 1300 similar to 1600Ma, 900 similar to 950Ma, 700 similar to 800Ma, 540 similar to 560Ma, 400 similar to 500Ma and 270 similar to 290Ma. The SHRIMP U-Pb zircon dating of the central aeromagnetic anomaly zone yields the age of 1908.2 +/- 8.6Ma, which revealed that there was granitoid basement by Palaeoproterozoic tectonothermal event. By the dating data with new geology and geophysics data, there are different age and type of Precambrian crystalline basements in Tarim basin, which divided into the northern basement with Meso-Neoproterozoic low-to medium-grade metamorphic rocks, the middle basement of Palaeoproterozoic granite, the southern basement with Early-Middle Neoproterozoic magmatite and metamorphite, the southeastern metamorphite basement undergone reformation in Early Silurian epimetamorphism. It is found that there is a wide range unconformity between Cambrian and Precambrian by well and seismic date,which developed the northern and southern basement palaeo-uplifts as the result of the potential influence of Pan-African orogenic occurred about 550Ma. The basement palaeo-uplifts undergone 5 stages evolution: the cratonization miniature basement in Archean-Middle Palaeoproterozoic, the united metamorphic crystalline basement in Early Neoproterozoic, the two basement palaeo-uplifts formative stage before Precambrian, the five basement palaeo-uplifts complete period in the late of Caledonian and local regulation since Hercynian. |
