Abstract Tectonism has played a significant role in the formation of many coal basins throughout the world. In addition, tectonic factors provide stability or instability for peat accumulation and are catalysts for detrital influxes that terminate mires (Lyons and Rice, 1986; Korsch and Totterdell, 1995). Tectonic processes, such as folding and faulting, modify the coal deposit. Deciphering the tectonic history of a region and identifying the location and character of faults can be a challenge. A fault is a natural break in strata where opposing block(s) have been subjected to movement. There are many fault classifications in the literature, most being based on genetic stress regimes and/or geometric configurations. Faults within coal deposits are derived through the processes of tectonism, sediment compaction, combustion, and glaciation.
