Conodont colour alteration data for the Lower Palaeozoic strata of the
North Greenland carbonate platform indicate a pattern of increased th
ermal maturity northwards within the Franklinian Basin. There is littl
e variation in values through the Canadian-Llandovery (Lower Ordovicia
n-Lower Silurian) interval at any given locality. A simplified thermal
model for the platform suggests that the predominant control of conod
ont colour alteration and thermal maturation was maximum depth of buri
al, which occurred during the mid- to late Silurian. A preliminary int
egrated scheme for conodont and organic thermal maturity indicators ca
n be compiled from the data now available from North Greenland.
