Evolution of Basin-Range Pattern in Southwest Margin of Yangtze Block during Late Triassic to Early Jurassic: Evidence of Detrital Zircon U-Pb Geochronology from Chuxiong Basin
-
摘要: 印支期扬子西南缘沉积盆地大地构造性质及盆山格局演化过程长期存在较大分歧. 对楚雄盆地西侧祥云剖面上三叠统-下侏罗统砂岩样品进行碎屑锆石U-Pb定年和碎屑物源分析. 结果显示，上三叠统云南驿组和罗家大山组碎屑物源主要来自上扬子地区的中-下三叠统和二叠系，而上三叠统白土田组和下侏罗统冯家河组碎屑物源主要来自松潘-甘孜地体和康滇古陆. 结合沉积环境演变和区域地质背景，认为在晚三叠世早期，区域内造山作用相对较弱，楚雄盆地碎屑物源供给不足，为欠补偿盆地；晚三叠世晚期-早侏罗世，虽然楚雄盆地的构造演化受哀牢山造山带逆冲推覆作用的控制，但是楚雄盆地的沉积充填过程主要受控于快速崛起的松潘-甘孜造山带.Abstract: There exist divergent views about the Indosinian tectonic nature of basin and the evolution of basin-range pattern in the southwest margin of the Yangtze block. Detrital zircon U-Pb dating and detrital provenance analysis of sandstone samples from the Upper Triassic-Lower Jurassic of Xiangyun Section in the western Chuxiong basin were carried out. The results show that the detrital sources of the Upper Triassic Yunnanyi Formation and Luojiadashan Formation are mainly from the Middle-Lower Triassic and Permian in the Upper Yangtze region. The detrital sources of the Upper Triassic Baitutian Formation and the Lower Jurassic Fengjiahe Formation are mainly from the Songpan-Ganzi terrane and Kangdian ancient land.Combined with the sedimentary environment evolution and regional geological setting, it is considered that the orogeny is relatively weak during the earlier Late Triassic, and Chuxiong basin is an underfilled basin, whose clastic source supply is insufficient. From the later Late Triassic to Early Jurassic, the tectonic evolution of Chuxiong basin was controlled by the thrust nappe of Ailaoshan orogenic belt, but the sedimentary filling process of Chuxiong basin was mainly controlled by the rapid rise of Songpan-Ganzi orogenic belt.
