Abstract: Development of a small, shallow basin for the deposition of the Bongaya sediments of late Miocene age in the Pitas region was controlled by earlier faults trending NE-SW, N-S and NW-SE on the underlying rocks of the area (Crocker and Chert-Spilite Formations). This nearly circular-shaped basin was filled by sediments sourced from older uplifted rocks to the east, south and southeast by the overlapping of numerous fluvio-deltaic fan lobes.
