Fig. 2. Formation environments and characteristics of supported gravels. (a) Supported gravels formed by sieve deposits in Jiangjungou at the southern margin of the Junggar Basin, with the maximum diameter of over 1 m; (b) Foothill colluvial fan near the Baiyanghe fan, formed by rock fragments generated by weathering of the nearby mountain rock (c) Supported gravels distributed linearly along the grooves on the foothill colluvial fan, with the small picture showing the location of the sand yard; (d) Supported gravels on the bed of Baiyanghe river, 5-30 cm in diameter, tending upstream. |
