Although an aeolian origin for the siliciclastics of the Permian (Guad
alupian) Delaware and adjacent basins and shelf has been recognized, t
heir source has remained elusive. An Ancestral Rockies source to the w
est and northwest has been traditionally favored. We propose instead t
hat these sediments were derived from aeolian systems to the northeast
and represented by the Whitehorse Group in the Anadarko Basin. This h
ypothesis is based upon (1) recognition of the aeolian nature of the W
hitehorse, (2) regional correlation of the Whitehorse Group with porti
ons of the Artesia Group, (3) paleoclimatic model-predicted and measur
ed southwestward sediment transport for the Whitehorse, and (4) a prop
osed transport corridor over emergent mudflats along the northern marg
ins of basins in the Texas Panhandle and onto the New Mexico shelf. Po
tentially, a Whitehorse-Artesia link could show the formation of this
mixed carbonate/siliciclastic system as the result of the interactions
of diverse and distant environmental systems under eustatic and clima
tic forcing factors. (C) 1998 Elsevier Science B.V. All rights reserve
