“…Westward downcutting on the J-0 unconformity requires tilting toward the east and associated erosion of progressively older strata to the west [Marzolf, 1991]. Marzolf [1991] suggested that this regional- 3 and 4). We suggest that this change may have occurred as early as J-1 time (-175 Ma), because the J-2 probably is a composite unconformity east of the sequence 3 pinch-out.…”

“…The direction of downcutting on major unconformities is important because it provides information about the geometry and possible origin of regional tilting episodes that produced the unconformities. Westward downcutting on the J-0 unconformity requires tilting toward the east and associated erosion of progressively older strata to the west [Marzolf, 1991]. Marzolf [1991] suggested that this regional- 3 and 4).…”

“…The lower Dinosaur Canyon Member thus correlates with the Church Rock Member of the Chinle Formation and the Wingate Sandstone [28] to the east. To the west, in southern Nevada and southeastern California, thinning and unfossiliferous sediments equated with undifferentiated Moenave and Kayenta formations underlie the eolian Aztec Sandstone [29] .…”

“…The feature marks a two-million-year-long depositional hiatus in parts of the plateau (Marzolf, 1994;Blakey, 1994;Tanner, 2006, 2014). These varying unconformities have been linked to the initiation of the Cordilleran magmatic arc and associated thrusting along the western continental margin (Reynolds and others, 1989;Marzolf, 1991).…”
