Description: Glacial varves from Lake Xinluhai (Tibetan Plateau). A: Flatbed scan of thin section. B: Micro-photograph under a stereoscopic microscope with polarized light. Varves appear as couplets of light silt and dark clay layers. Silt grades upward into fine clay, then the clay layer sharply contacts with the silt layer of the next year. Some rhythmites can be found within the silt layer.
