Stratigraphy
Geological group:Mata Formation:Tahora Member:Maungataniwha
Stratigraphic resolution:group of beds
Stratigraphy comments: Upper layers of formation, age of layer is early Hamurian according to Eagle (1994), about 100 m above the Piripauan-Hamurian boundary.
Lithology and environment
Primary lithology:wave ripples,"cross stratification",bioturbation,concretionary,nodular poorly lithified calcareous sandstone
Includes fossils?Y
Includes fossils?Y
Lithology description: Moderately indurated, poorly bedded, fine-grained, highly bioturbated, grey-mottled sandstone and lenticular shell-beds. Low angle planar cross-bedding and minor, low amplitude symmetrical ripples are also prevalent (Crampton & Moore 1990). Calcareous and phosphatic concretions and pyrite nodules are locally common in the exposed strata. The upper part of the unit is highly fossiliferous and rich in finely comminuted plant material, slightly glauconitic near the top. A coarse pebble to cobble basal conglomerate 50-60 m thick containing blocks of grey wacke, ripped-up sandstone clasts and minor lenses of carbonaceous mudstone and coal interfingers with the sandstone.
Environment:shoreface
Geology comments: Presence of low-angle planar cross-bedding and symmetrical ripples suggests a shoreface environment.
