“…Although no fossils were found in this outcrop a very similar sequence of sediments associated with minor shell beds was found in Lime and Marble Company boreholes W34 and W33, and the whole sequence is included here in the marine Greenwood Formation. Lithologically the beds are similar to those described by Gregg (1959) from Lower Waipara, and a column erected for the Coalgate area is shown in Fig. 5.…”

“…To the north-east, Burnt Hill Group is contemporaneous with at least the upper portion of the fully marine calcareous Mount Brown Beds (Thomson 1920;Wilson 1963), Double Corner Shellbeds (Gregg 1959) of the Waipara district, and muddy and calcareous sandstones of the Mandamus-Pahau area (beds M7-9 of Mason 1949) of Mount Grey. In this general area both dominantly calcareous and dominantly non-calcareous lower to middle Miocene sequences occur, suggesting the interfingering of coeval lithofacies.…”

“…The age of Greenwood Formation at Waipara is regarded as Waipipian, possibly Nukumaruan (Gregg 1959), and this age is accepted for the Coalgate area. Gregg (1959) correlated the type Greenwood Formation of Lower Waipara with the Mount Grey area (lowest part of Mason's Kowhai Series) and with Motunau or Greta beds in the Middle Waipara and Weka Pass (Thomson 1920). In these areas the equivalent units pass up gradationally into the non-marine lower Pleistocene Kowai Gravels.…”

Stratigraphic and sedimentologic studies of the Cretaceo-Tertiary sequence overlying Torlesse rocks in the Coalgate area permit a review of the lithostratigraphy of the region. Much new information has come from borehole logs and cores. Coal measures conformably overlain by shallow marine strata and associated igneous rocks, including View Hill Basalt, are assigned to the Eyre Group (modified name) of upper Cretaceous and possibly Paleocene age. Burnt Hill Group (new name) is erected to accommodate some 200 m of Oligocene-Miocene non-calcareous marine, estuarine, and associated igneous rocks of central and northern Canterbury. Formations include: Homebush Standstone (new name for a massive estuarine deltaic deposit) (oldest unit); Thongcaster Formation of Duntroonian age (new name for a fossiliferous clayey fine sandstone); Wairiri Volcaniclastite (new name for a tuff-breccia deposit); Chalk Quarry Sandstone of Waiauan age (modified name); Chalk Hill Clay; Sandpit Tuff (name now formalised) consisting of sandy and silty tuffs and tuff breccias; Bluff Basalt (name now formalised) including breccia, flow and dike rocks; Harper Hills Basalt (name altered and restricted in usage); Coalgate Bentonite (rank of unit changed) (youngest unit). Burnt Hill Group is overlain by 55 m of sandstone and sandy mudstone of Greenwood Formation, of probable Waipipian age, and up to 40 m of viviantic sands, clays, and gravels of possible Castlecliffian and perhaps younger age which are included in Aitkens Formation (new name). Much of the area is blanketed by Hawera Series outwash gravels which help to obscure the stratigraphic relationships of older formations in surface exposure.

Recent work has resulted in recognition of an additional glaciation preceding the Waimaunga Glaciation in the late Pleistocene. This followed the mid-Pleistocene climax of earth movements responsible for most of the present mountainous relief of New Zealand, but only after an interval of time long enough for the construction and subsequent deep dissection of Banks Peninsula shield volcano. It is inferred from this and other geological evidence that the earliest late Pleistocene glaciation was separated from the early Pleistocene Ross Glaciation by several hundred thousand years, and that the Pleistocene Period altogether covers at least one million years.
