Investigation of the structure of the Todilto limestone in the Grants district indicates a genetic relationship between the Todilto folds and joints resulting from the Zuni uplift.nDrill-hole data from three test areas indicate that most ore bodies in the Todilto lie on anticlines or synclines, the larger ones on anticlines. The larger ore bodies are elongate in a manner that suggests control by a conjugate joint system. Finally, ore bodies appear to trend in general conformity with the structures.
