The objective of this study is to identify the most suitable portions of the C1 coking coal seam in the North Block of the East-Parvadeh coal deposit (Central Iran), according to ash and sulfur values, using C-N fractal modeling. Based on the C-N log-log plots, different geochemical populations were evaluated based on their sulfur and ash content. They were then divided into five populations each according to their sulfur and ash percentages. The first sulfur containing population, located in the northern and western sections of the area, contains the best quality coking coal. The sulfur content ranges from 0-1.51%, known as “very low”. Situated primarily in the western and northeastern sections of the North Block are two ash populations with ash values between 0 and 12.88%. Known as “very low” and “low”, they are also of suitable quality for coking coal.
