藏南江孜地区白垩系海相红层中红色页岩的颜色成因 薛纪越1,蔡元峰1,李响1 (1.南京大学,地球科学与工程学院,江苏,南京,210093;2.南京大学,金属成矿作用机制国家重点实验室,江苏,南京,210093) 摘要:白垩系大洋红层(Cretaceous Oceanic Red Beds,CORBs)在我国西藏江孜地区广泛发育,以床得组最为典型.本文以床得组红色页岩为研究对象,通过电子探针背散射电子像观察和成分定量分析,主量元素分析,X射线衍射分析,结合CBD(Citrate Bicarbonate Dithionite)提取铁氧化物前后漫反射光谱分析,认为床得组红色页岩中的铁氧化物只有赤铁矿,没有其它铁氧化物,赤铁矿是唯一的致色铁氧化物.电子探针背散射电子图像显示,赤铁矿分为结晶好和结晶差的两种形态.CBD提取前后反射光谱红度的变化,指示结晶差的赤铁矿的致色作用要远大于结晶好的赤......
