新疆北天山地区的岩石漆中发育有横向上连续的黑色和橙色显微层理 .电子探针显微化学分析表明 ,岩石漆中黑色层理富含锰 ,而橙色层理相对只含少量的锰 .岩石漆超薄切片的光学显微镜分析揭示 ,岩石漆的显微层理结构在区域尺度上具有一致性和可对比性 .根据采样面的地貌年代控制 ,初步建立了北天山地区全新世以来岩石漆的显微层理层序 .并基于研究区现有的区域古气候资料对该层理层序的古气候意义做了探讨
Lateral and continuous black and orange microscopic stratification is developed in the rock paint in the north Tianshan region of Xinjiang.The microscopic chemical analysis of the electron microprobe shows that the black stratification of rock paint is rich in manganese while the orange stratification is relatively small Light microscopic analysis of manganese and rock thin sections revealed that the microlayered structure of rock lacquer was consistent and comparable at the regional scale.According to the control of the geomorphology of the sampling surface, the initial establishment of the North Tianshan area since the Holocene Rock lacquer microlayered sequence.And based on the existing regional paleoclimatic data in the study area, the palaeoclimatic significance of this layering sequence was discussed
