Description
The inner shelf of the Great Barrier Reef province is characterized by active terrigenous sedimentation. In the area south of Townsville, the Burdekin River acts as a major point source of fine grained clastic sediment and contributes 3.5 x 10^6 tonnes per annum to the inner shelf. An examination of the sedimentation patterns in this area, based on 240 subtidal samples and extensive examinations of tidal flat, mangrove and supratidal terrains, has revealed that by far greatest volume of Holocene marine sediment is contained in a prograding sequence of intertidal coastal sediment bodies. Vertical accumulation on the inner shelf is limited and negligible sedimentation is occurring on the middle shelf. ...
