Description: Coals form in depositional settings sensitive to
changes in relative sea-level such as coastal mires & delta tops, making
them high resolution recorders of changes in sea-level, salinity, climate and
sediment supply. Integration of detailed coal petrographic analysis with
sequence stratigraphy can provide a timely model for the high resolution
stratigraphic responses of ancient coastal wetlands to changes in sea-level.
The key issues of this research are 1) the stratal, petrological and
geochemical expressions of base-level change within the coal seam; 2) the
significance of laterally extensive coal seam splits in terms of palaeofloral
and water table changes across the whole peat swamp; and 3) the exact timing of
coal formation with respect to delta progradation and subsequent
flooding. |
