| Lithology description: At its type section about 80 km northeast of the Xiaerhete locality, the Irtysh River Formation is characterized by pale gray, greyish yellow, and light brown mudstone, siltstone, and sandstone beds that are interbedded with reddish and purplish variegated crack layers and dark brown ferruginous layers. At the Xiaerhete locality, the sediments have similar crack layers and ferruginous layers, but the color is slightly less variegated | |
