This report deals with the regional stratigraphy of surficial deposits in the region of the Murray Basin and adjoining Gambier Embayment of the Otway Basin. The aim is to place deposits described in selected earlier publications of anthropologists, geologists, geomorphologists, pedologists and others into the regional stratigraphic framework prepared by the writer. The original source of material by other authors is acknowledged wherever possible in the text. Any difference in emphasis and interpretation resulting from the incorporation of so much material written at other times and with other aims is the present author's responsibility. The stratigraphic framework is the result of a state-wide study of surficial deposits commenced in 1964. During the study, physical sequences were first described in terms of depositional environment and time of formation, and geological events were inferred (Firman, 1967b). This work was later revised and set out in terms of natural regions in Firman (1969a). Relationships between surficial deposits and soils were described in Firman (1968; 1969c and 1970a). The distribution of units and their stratigraphic position as now understood is shown on the regional map and stratigraphic table. Most emphasis is placed upon sedimentary materials within the basins proper. Weathering profiles and provenance areas in the highlands of the basin margins are not discussed in detail, and soil and landform are discussed only where they are important in the reconstruction of events. The oldest deposits are described first. This approach favours an evolutionary treatment and the description of successive geological events. Emphasis is placed upon the environment prevailing earlier at the time of deposition and later in the present landscape. This emphasis is essential, because environment controls both the kind of parent material and its condition in the modern regolith. There is some overlap of discussion in the text, because certain depositional environments are maintained for a considerable period and other depositional events are initiated elsewhere during this time. It is particularly important for stratigraphic purposes to determine when a deposit first made its appearance in the landscape, and also to relate katamorphic events to the sediments with which they are stratigraphically associated. These reasons have made it necessary in some places to discuss separately those deposits, which although similar and occurring together in the same area, are of very different age.
