The Organic Maturation Levels of Carboniferous Rocks in South County Wexford, Ireland

Organic maturation levels of the Carboniferous rocks of the Wexford Outlier and Hook Head (0.77% - 2.54% Rm; CAI 3 - 4) are considerably lower than those of Carboniferous strata in adjacent areas. Results are presented from 54 vitrinite reflectance, 15 spore colour (TAI)/fluorescence and 53 conodont...

Description
Summary:Organic maturation levels of the Carboniferous rocks of the Wexford Outlier and Hook Head (0.77% - 2.54% Rm; CAI 3 - 4) are considerably lower than those of Carboniferous strata in adjacent areas. Results are presented from 54 vitrinite reflectance, 15 spore colour (TAI)/fluorescence and 53 conodont colour (CAI) determinations. These date show that observed maturation levels in the Wexford Carboniferous can be attributed to normal burial processes, and that the present maturation levels may have been attained during late Carboniferous times. However, the maturation level of the youngest known Carboniferous in the area, the Westphalian D Richfield Formation, may be due to post-Variscan burial.
