Geochemistry of drillcore Bing Bong 5, McArthur Basin, NT

Abstract

Bing Bong 5, drilled by Shell in 1982, is one of a number of wells drilled in the McArthur Basin that intersect Paleoproterozoic organic-rich rocks. The well intersects the Lynott Formation from 0 m to 60.28 m, the Reward Dolostone from 60.28 m to 214.6 m, the Barney Creek Formation from 214.6 m to 352.65 mj, and the Teena Dolostone from 352.65 m to 370 m at total depth. This data release contains the results of a geochemical study of Bing Bong 5 and includes mineralogy from X-ray diffraction (XRD), source rock characterisation from Rock-Eval pyrolysis and trace metal data from Xray fluorescence (XRF) and quadrapole inductively coupled plasma mass spectrometry (Q-ICP-MS). This work was carried out in the Isotope and Organic Geochemistry, and Inorganic Geochemical Laboratories at Geoscience Australia and was undertaken as part of the Australian Source Rock Study Project.

All rocks analysed in this study are listed in the supplementary information, of which the 61 samples analysed covered three formations; the Lynott Formation, the Reward Dolostone and the Barney Creek Formation including the Here's Your Chance (HYC) Pyritic Shale Member from 302.16 m to 318.35 m.
