Palynological counts: raw counts of the palynofacies analysis. Includes MPA (micropalaeontology sample number), SSK (subsample Keyworth) number provided by the National Geological Repository; Depth in meters; the raw counts grouped by Heterogeneous amorphous organic matter (AOM), Homogeneous AOM, Phytoclasts, Spores and Pollen, Fungal debris and Mineral Matter. 3. Thermal Maturity as random mean vitrinite reflectance data: includes SSK sample number, depth in meters; mean random vitrinite reflectance (%Rr), Standard Deviation (SD) and the number of measurements taken for each sample (n). 4. Spore counts: Includes MPA (micropalaeontology sample number), SSK (subsample Keyworth) number provided by the National Geological Repository; Depth in meters; raw counts of spores identified in selected samples. All the data are based on sample materials from the Holywell Shale Formation from the Ellesmere Port 1 Borehole. These data are in support of: Hennissen et al.’s The Holywell Shale Formation in the Blacon Basin: resource potential in the Geological Society of London Special Publications.

Residual carbon was oxidised at 300–850 °C at a rate of 20 °C/min. Hydrocarbons released were measured using a flame ionization detector while CO and CO2 were measured using an infra-red cell. Palynology: 5 g of crushed sample material was broken down using HCl (36%) and HF acid (40%) to dissolve and decant carbonates and silicates. After neutralisation w the remaining kerogen was sieved on a 10 ?m nylon mesh and strew mounted on microslides using Elvacite™ 4345. Vitrinite reflectance: Aliquots of the kerogen isolates obtained using the palynological preparation protocol were strewn on a PTFE treated cover slip and mounted on a microslide using Metprep™ Kleer-Set polyester resin.
