Formatted abstract
Some aspects of the land and marine geology of the Point Vernon area, Hervey Bay, Queensland are presented. The Lower Cretaceous Maryborough formation (6,000 feet, mainly marine) and the Burrum Coal Measures (8,000 feet, mainly fluviatile and lacustrine) are compositionally
alike and consist of volcanite bearing arkosic sandstones, mudstones, and silt-shales. The Burrum Coal Measures also contain coal seams and intraformatioual mud-pebble conglomerates.

The Lower Cretaceous strata vere folded during the Late Cretaceous Maryborough Orogeny and hare since undergone a complex diagenetic history. The Early Tertiary Takura Beds (a talus deposit of oligomictic breccia) and the Elliott Formation (fluviatile orogenic orthoquartzite) were extensively lateritized after the extrusion of the Dundowran Basalt (olivine basalt).

The recent marine sediments in this area are mainly carbonate rich, quartzose, gravelley, fine and medium grained sands. The marine area has been subdivided into a number of physiographic zones, based on considerations of bathymetry, hydrography, coastal morphology, and organisms. These factors control the sediment characteristics, which can be used to define facies groups. A five component system was used to evaluate the finer details of the active sedimentary processes.

Interpretations of continuous marine seismic profiling showed that the Urangan Syncline is a broad feature. Within this the Cretaceous strata are tightly folded into a series of extremely linear, north-north-westerly plunging anticlines and synclines.
