Geological assessment of the structure and stratigraphy of several districts. The Waingaromia Structure has definitely been proved to be connected with the Tauwhareparae Structure to the N by a long regional fold. The extensive outcrops of Upper Mangatu rocks exposed in the central portion of this area are flanked by steep-dipping Lower Ihungia and Wheao beds, which have been overlapped by flat-dipping Tutamoe sandstone. Overthrust faulting is recognised as controlling the attitude and distribution of the Mangatu rocks along the W flank, but the boundaries of the Mangatu and overlying Tertiary rocks on the other flanks represent a normal contact revealed by erosion of the upper members and not complicated by any system of faults. Although the structural conditions are recognised as not being ideal, they are well understood and no argument can be logically made to show why, if oil is present at depth in the Mangatu rocks at Waitangi, it should not be also present at depth on the Structure 8 side of the Waingaromia Syncline.
