From abstract: This report describes the depositional environments of the Chinle Formation that was deposited in a complex fluvial-deltaic-lacustrine system in the area of the present-day eastern San Juan basin and Chama basin. Lithofacies include conglomerate and planar- and trough-crossbedded sandstone; bentonitic mudstone and sandstone; black, organic carbon-rich mudstone; large-scale, trough crossstratified siltstone, sandstone, and mudstone; and thickbedded, bioturbated, fine-grained sandstone and siltstone.
