Abstract
Summary
Oil-proneType I and Type II kerogens, as well as oil/gas prone Type II-III kerogens, considered capable of generating oil and gas at higher maturity within the area.
Biomarker signatures [n-alkanes >n-C25 are dominant, high C29/C30 17α (H) hopane ratios (1.10–3.3) & high C29 steranes (49.0–71.3 %)] and chemical compositions [low total sulfur and V/(V+Ni) ratio] suggest a predominantly terrestrial source input with some contribution from aquatic microorganism as indicated by common occurrence of amorphous organic matter.
