Abstract:
Data compiled from some 32,000 coal exploration borehole records were used to demonstrate the inter-relationship between the distribution patterns of thick coal seams, their splitting patterns and thick interburden relative to depositional environment, basement structure and fluctuating base levels (ACARP Supermodel 2000 Project). Four major coal ‘superseams’ occur within a southerly thinning terrestrial clastic wedge that can be correlated along a 250 km subcrop of the Moranbah and German Creek Coal Measures on the western limb of the Bowen Basin, Queensland. Seams split and merge along strike, but areas of thick, >10 m merged seams in the northern alluvial environment tend to occur over areas of stable basement domains interpreted from regional gravity.
