The geology of the Coromandel subdivision, Hauraki, Auckland . side of a ridge of land consisting of Tokatea Hill andMoehau rocks. The former is the more feasible hypothesis. The relationship of the Manaia Hill Series to the Tokatea Hill and Moehau Series has been consideredin earlier sections of this chapter. In correlating the various isolated areas on both sides of the peninsulawith the undoubted Jurassic strata of the Manaia Hill, the writers have relied almost entirely upon thephysical and mineralogical character of the rocks. At Tawhetarangi, twelve miles north of Manaia,there was discovered in the fine conglomerates a small fragment of the prismatic layer of a bivalveshell(?) agreeing in structure with similar m?„terial from Manaia Hill. This discovery affords con-siderable support to the deductions based on physical and mineralogical data. The widespread occurrence of fine conglomerates and grits is evidence of sedimentation in com-paratively shallow water. Igneous material has contributed very largely to these sediments.
