Abstract: Middle Triassic strata of the Moenkopi Formation and Upper Triassic strata of the Chinle Group are
correlated from the Colorado Plateau eastward across the northern Rio Grande rift to the southern High Plains
of eastern New Mexico. This correlation demonstrates the continuity of Middle and Late Triassic deposition
across northern New Mexico and significant (tens of meters of) stratigraphic relief on the Tr-1, Tr-3, and J-2
unconformities. Relatively little regional stratigraphic relief on the Tr-4 unconformity is consistent with previous
interpretations that suggest that it is an intrabasinal unconformity that represents a relatively brief temporal
hiatus in deposition.
