摘要
甲基-2-甲基-2-(4,8,12-三甲基十三基)色满(M-MTTC)的分布与沉积环境有关。在抚顺烛煤中发现5,7,8-三甲基-MTTC和5,8-二甲基-MTTC以及7,8-二甲基-MTTC,不存在一甲基-MTTC。M-MTTC的这种分布反映了抚顺烛煤的淡水滨湖相沉积环境。与此相应的是,抚顺烛煤含有C_(32)—C_(35)苯并藿烷,具有很高的姥鲛烷/植烷比值,高碳数正烷烃的奇偶优势和C_(24)—C_(34)异构烷烃的偶奇优势。
The distribution of methyl-2-methyl-2-(4, 8, 12-trimethyltridecyl) chromans (M-MTTC) is related 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 that M-MTTC is widely spread in sediments. The distribution of M-MTTC, the presence of C32-C35 'benzohopanes, high Pr/Ph ratio, obvious even-odd predominance in C24-C34 380 alkanes and odd-even pre-dominance in normal alkanes provide strong evidence of a nearshore lacustrine environment.
