Stratigraphy
Geological group:Stranraer Formation:Naseby Greensand
Stratigraphic resolution:bed
Stratigraphy comments: Listed as "probably middle bed of greensand". Described in text as from units of the Naseby Series (now Naseby Greensand), part of the Pareora Formation of Hutton (1875). From Bishop (1979): Naseby Greensand (Stranraer Group) is approximatey 250-300 m thick, underlain by metamorphosed schist or siltstone of the Eocene Swinburn Formation (Stranraer Group), and overlain conformably by current-bedded quartz sands and gravels of the late Oligocene/early Miocene Wedderburn Formation (Stranraer Group).
