THE CLASTIC COMPOSITION CHARACTERISTICS OF UPPER PALAEOZOIC GLUTENITE IN NORTHEAST QAIDAM EDGE AND THE STRUCTURAL ATTRIBUTES OF SOURCE AREA

  • 摘要: 基于柴东北缘德令哈地区上古生界126件碎屑岩样品的镜下鉴定, 结合对牦牛山组、城墙沟组、怀头他拉组、克鲁克组及扎布萨尕秀组砂砾岩岩石学特征、沉积特征的野外调查, 研究柴达木东北部地区晚古生代碎屑岩物源区, 并在此基础上进一步讨论该地区晚古生代盆山格局。研究结果表明, 柴东北缘德令哈地区晚古生代主要发育扇三角洲-障壁海岸沉积体系, 砂砾岩碎屑颗粒结构成熟度较低, 重力流证据普遍存在; 各层段砂砾岩碎屑颗粒中Q/(R+F)值在1.89~3.74之间, 呈现低成分成熟度特点。碎屑颗粒组成及近物源沉积证据一致表明, 研究区晚古生代以鱼卡-沙柳河加里东期造山带为主要物源区。该造山带至少存在了195 Ma, 包括距今465~430 Ma的山体隆升与距今430~270 Ma的山体剥蚀阶段。柴达木海盆与德令哈海盆是两个独立的海盆, 发育展布方向完全相反的沉积体系。同时, 德令哈地区上古生界含油气系统勘探应将鱼卡河-沙柳河高压-超高压变质带视为勘探边界。
