Abstract

Lying 125 km west of Brisbane on the escarpment of the Great Dividing Range, the conurbation of Toowoomba is mainly floored by basalts and associated rocks of the late Tertiary Main Range Volcanics (MRV). Land surfaces including lateritic profiles developed before, during and after the eruption of the MRV. Subsequent latest Tertiary and Quaternary denudation has resulted in westward migration of the Great Divide with the development of the east-facing escarpment. The topography and soils developed on these rocks provide a range of surficial conditions which must be considered in urban planning and development. Located on the Great Divide, the conurbation depends chiefly on pumping from surface reservoirs at lower levels for its water supply; groundwater from aquifers in the MRV represents both a source of supply and a strategic resource. The MRV provides blue metal and road base.
