چکیده انگلیسی
⺠These coals have a fluvial deposition as supported by increasing ash yield and a low (< 1%) CaO content. ⺠Coal formation initiated under oxic condition followed by increased water cover in the paleomire. ⺠Carbon isotope data of coal and associated sediments indicate their terrestrial source. ⺠This contention is also revealed in petrography, gelification and tissue preservation indices. ⺠Vitrinite has enhanced the â13C as revealed by their correlation (r = 0.849).
