Upper Palaeozoic strata of West Texas record the convergent history of a portion of the southern North American continental margin and associated development of the Marathon and Val Verde basins.
The Tesnus, Dimple and Haymond Formations (Chesterian—Late Atokan; 3,400 m thick) of the Marathon area were formed within a probable remnant ocean basin setting in part developed adjacent to the more eastern Kerr peripheral basin. The Gaptank, Neal Ranch, Lenox Hills, ‘Wolfcamp’, and equivalent Permo–Pennsylvanian formations (Late Desmoinesian–Late Wolfcampian) were deposited in orogenic clastic wedge, starved basin, submarine fan, and shelf/platform settings (Val Verde Peripheral Basin Facies). A maximum preserved thickness of 6,200 m is present near the southern Val Verde basin margin.
We suggest that structural weaknesses developed in the Late Precambrian/Early Cambrian were reactivated in the late Palaeozoic as reverse faults in response to compressional stresses. These reactivated structural elements, in conjunction with Ouachita orogenesis, apparently influenced the distribution of intrabasin palaeohighs and concomitant patterns of sedimentation. Northward migration of the Val Verde basin axis was accompanied by continued fold-thrust belt development and reworking of earlier deposits of the Val Verde Peripheral Basin Facies.
