    Abstract

    Concentrations of organic carbon in samples from the Peterborough Member ranged from 0.5 to 16.6% and δ values of total organic carbon (TOC) ranged from -27.7 to -23.1‰ v. PDB. Isotopic composition of pristane and phytane in the Peterborough and Stewartby Members average -31.7‰, those in the Weymouth Member average -29.8‰. Values of δ for long-chain n-alkanes average -28‰. Together these indicate δ values for primary inputs as follows: terrestrial vascular plants, -23.5‰; Peterborough Member algae, -28.2; Stewartby Member algae, -29.1‰; Weymouth Member algae, -26.6‰. -from Authors
