interval_notes:	Quartzose, coal-bearing siliciclastics 690 m thick form the Huobachong Formation. Thick-bedded, cross-stratified sandstone and conglomerates are amalgamated into thinning- and fining-upward intervals separated by blocky mudstones. This fining-upward motif continues into the overlying Erqiao Formation, but coals are lacking." (Enos et al., 1998, 2006). Interpreted as braided streams from the west (molasse). Base placed at base of Norian; but poor age control.
