In recent years five wells have been drilled in the rearward areas of the Ouachita folded belt. These wells, under the old conception, should have either encountered pre-Cambrian rocks or the ordinary sequence of dark, steeply dipping, varyingly metamorphosed beds characterizing the Ouachita folded belt. Instead, these wells, under the normal thickness and facies of Mesozoic formations, found Paleozoic beds that showed no evidence of metamorphism, and that exhibited flat dips in cores. It is proposed to describe these occurrences in some detail and to assess the effect they have on presently held theories concerning Llanoria and the Ouachita folded belt.
