Late Devonian Turbidite System and Tectonics of Zhen'an Basin at Northern Margin of South Qinling

  • 摘要: 南秦岭北部山阳断裂和板岩镇断裂之间的镇安盆地在晚泥盆世发育—套浊流沉积。通过对这套浊积岩系内部岩相、相组合、古流向等详细研究,结果证明其内部由斜坡沉积、水道—天然堤沉积、舌状体沉积以及盆地平原等单元组成,然而它们的空间组合及内部特征并不代表一个典型的水下扇沉积体系,而是反映一个由线状物源供给的缓坡型浊积岩体系。晚泥盆世浊积岩体系是随中记盆世碳酸盐台地发生沉陷而随之发生的,反映镇安盆地当时为一个相对狭窄的断陷式盆地。区域构造分析证明,盆地的形成和发展与南、北秦岭发生初始碰撞而引起的俯冲板块前缘挠曲隆升和上部地壳伸展作用有关。
