The geology of the flat point area, eastern Wairarapa

Summary The stratigraphy and structure of the Flat Point area, eastern Wairarapa is described and illustrated by a map. Strata in upward succession are: Mokoiwian greywackes with spilites; Ngaterian to Piripauan graded‐bedded sandstone, siltstone and conglomerate; Haumurian and Teurian brown siltstone with glauconitic sandstone; Lower Dannevirke limestone and greensand; Upper Dannevirke and Bortonian bentonitic siltstone and greensand; Pareora and Southland alternating sandstone and siltstone. Dolerite intrusions that cut Ngaterian and Raukumara strata have alkaline affinities and are co‐magmatic with teschenites described to the north. The strata are strongly folded along north‐north east fold axes, and are disrupted by parallel faults.
