The Occurrence and Geochemistry of Di-and Trimethyl-2-(4,8,12-trimethyitridecyl)Chromans and Benzohopanes in Fushun Cannel Coal,Northeast China
The distribution of methy1-2-(4,8,12-trimethyltridecyl)chromans (M-MTTC)is relat-ed to sedimentary environments.5,7,8-tri-Me-MTTC,5,8-di-Me-MTTC and 7,8-di-Me-MTTC have been found in coal for the first time,implying thatM-MTTC is widely spread in sediments.The distri-bution of M-MTTC the presence of C32-C35 benzohopanes,high Pr/Ph ratio,obvious even-odd pre-dominance in C24-C34 alkanes and odd-even predominance in normal alkanes provide strong evidence of a near-shore lacustrine environment.
