Statement

Three positions in the Craven Basin were selected for analysis; outcrop Hind Clough (grid ref: 364430 453210, British National Grid projection) and boreholes Marl Hill 4 (MHD4) (grid ref: 367426 446752) and Cominco S9 (grid ref: 386010 463500). The stratigraphic framework was based on recognition of ammonoid biozones, enabling correlation. True thicknesses at Hind Clough were estimated using the dip and strike of bedding with an Abney level. 341 samples were collected using hammer and chisel from Hind Clough ('HC02' prefix in dataset), and MHD4 and Cominco S9 core sampled at the British Geological Survey. Samples were cleaned, dry/ wet cut and some surfaces polished depending on sample quality, photographed and described prior to selection of subsamples. 100 homogenised powdered subsamples weighing approximately 10 g were selected for Rock-Eval pyrolysis, XRF and LECO elemental analysis. 74 samples were analysed for mineralogy (phase identification) using XRD. Samples were milled using an agate planetary mill and air-dried at 35 degrees C prior to pyrolysis. 90 ultrathin (20 µm) uncovered and uncoated sections were described using scans and transmitted light, and a subset analysed under scanning electron microscope. These data were interpreted together with 20 drill-core samples previously acquired from Hind Clough (‘HC01’ prefix). See http://dx.doi.org/10.5285/c39a32b2-1a30-4426-8389-2fae21ec60ad for further information regarding this drill-core dataset. 1.1. Organic Analysis Pyrolysis was conducted on finely powdered samples (60 mg subsamples) in a Rock-Eval 6TM apparatus (Vinci Technologies) at the British Geological Survey. Repeat measurements (n=3 to n=4) provide estimates for precision (two sample standard deviations) of less than ± 10 % for S1 and S2 parameters. Accuracy for total organic carbon (TOC) is reported at ± 7 %. 1.2. Elemental Analysis Total carbon (TC) and total sulphur (TS) were determined by analysis using a LECO CS 230 elemental analyser (30 mg subsamples). Accuracy is estimated at ± 5 % for C and ± 15% for S. Typical sample precision is estimated using two standard deviations at ± 3 % for C and ± 8 % for S. XRF data were acquired with a PANalytical Axios Advanced X-Ray Fluorescence spectrometer. Major element concentration was determined on fused beads using default PANalytical SuperQ conditions and trace element concentration was determined on 32 mm diameter pressed powder briquettes. Accuracy is estimated as ± 5 % for major elements and ± 5 % for trace elements. Similarly, precision (sample standard deviation) is typically up to ± 5 % (but commonly ± 1 %) for major elements and of ± 10 % (but commonly ± 5 %) for trace elements. These estimates are based on appropriate reference materials (repeat analyses). The majority of elements were detected in concentrations at least 10 times greater than the lower limit of detection. 1.3. Mineralogical Analysis Whole-rock powder XRD data were collected on a Bruker D8 Advance Powder Diffractometer equipped with a LynxEye Position Sensitive Detector with a Bragg Brentano, flat plate θ-θ geometry using CuKα radiation. Whole-rock data were acquired at a step size of 0.01° 2θ and step time of 0.5 seconds with a scan range from 0° to 135° 2θ. Scanning electron microscopy (SEM) was conducted on uncoated 'ultathin' sections using an S-3600N Hitachi microscope with Oxford INCA 350 EDS used for elemental mapping.
