摘要：

江南隆起一带下古生界煤化沥青的δ13C 值一般在-28‰左右,同上震旦统、下寒武统的石煤、炭质页岩相近,这说明它们之间有亲缘关系。下古生界煤化沥青δ13C 值比母质不同的河池煤化沥青轻约6‰,比腐殖煤轻7‰以上。

Abstract:

δ13C-value of carbobitumen from the Lower Paleozoic along the Jiangnan Uplift in the south of the Chang jiang River is generally about 28‰,which is very close to that of bone coal and carbonaceous shale from the Upper Sinian and the Lower Cambrian.This shows that they have close relations with each other.Carbobitumen from the Devonian in Hechi County,Guangxi,originated from Devonian sediments itself,which has something to do with the occurence of higher plants,δ13C-value of which is 6‰ heavier than that of the Lower Paleozoic carbobitumen.δ13C-Value of Lower Paleozoic carbobitumen is at least 7‰ lighter than that of humic coal in the same area,indicating that their origins are not guite the same.
