Abstract

Longtan coal measures of the Late Permian in Meishan

north Zhejiang Province

is a suite of delta sediments with a thickness of 130-240m. Oil can be found in sandstones there. The coal is bark liptobiolite. Its suberinite con-tent is 44.98-65.47%

and the tar productivity of dry distillation 9.3-21.4%.The coal-formed oil is rich in isoprenoid

cycloalkane

sterane and C

re-arranged sterane. All the Pr/Ph

Pr/n-C

and Ph/n-C

are greater than 1.The main peak of n-alkane is at C
