The sandstone sequence, which is about 35 m thick, fines upwards, becomes more thinly bedded and comprises more quartz-rich, mature sediment.
The pale green tuffaceous mudstone beds are medium bedded and contain abundant radiolarian fossils.
The formation consists of fine-grained, thinly bedded, silty sandstones and siltstones which were deposited in a turbidite setting.
These sediments are locally interbedded with siliceous limestone and rare thin-bedded sandstones.
