摘要：

利用穆斯堡尔效应可以测定生油岩中铁白云石的相对含量,进一步可以推断生油岩的成熟度。但白云石铁与岩石总铁量之比,还与岩性有关。本文用3口钻井22个样品的资料对此作了说明。

Abstract:

Relative contents of ferrodolomite in source rocks identified by Mössbauer effect can be used to deduce the maturity of source rocks.22 samples collected from 3 drill holes in Jurong County,Jiangsu Province,the Middle-Lower Triassic,Permian and Lower Silurian in age,are studied with this technique.The results suggest that Middle Triassic sediments are immatured or lowmatured source rocks,the ferrodolomite of them could hardly be found or found in the bottom,whereas Lower Triassic sediments are matured,the ratio of the iron contents of ferrodolomite to total iron increases with the increases of burial depth of the formation,and the ratio of mudstone samples is lower than that of limestone samples.As for the Lower Siluriam,Lower Permiam and the coal-series of the lower part of Upper Permian,the dolomite contents are naught possibly in relation to that they are supermatured.
