The analyses are performed by various laboratories in service and exploration companies, Australian government institutions, and universities, using a range of instruments. Sedimentary rocks that contain organic matter are typically referred to as source rocks (e.g., organic-rich shale, oil shale and coal) and the organic matter within the rock matrix that is insoluble in organic solvents is named kerogen. Data includes the borehole or field site location, sample depth, stratigraphy, analytical methods, other relevant metadata, and various data types including; elemental composition, and the stable isotopes of carbon, hydrogen, nitrogen, and sulfur. Results are also included from methods that separate the extractable organic matter (EOM) from rocks into bulk components, such as the quantification of saturated hydrocarbon, aromatic hydrocarbon, resin and asphaltene (SARA) fractions according to their polarity. The stable carbon (13C/12C) and hydrogen (2H/1H) isotopic ratios of the EOM and derivative hydrocarbon fractions, as well as fluid inclusion oils, are presented in delta notation (i.e., δ13C and δ2H) in parts per mil (‰) relative to the Vienna Peedee Belemnite (VPDB) standard. These data are used to determine the molecular and isotopic compositions of organic matter within rocks and associated fluid inclusions and evaluate the potential for hydrocarbon generation in a basin. Some data are generated in Geoscience Australia’s laboratory and released in Geoscience Australia records. Data are also collated from destructive analysis reports (DARs), well completion reports (WCRs), and literature. The bulk data for sedimentary rocks are delivered in the Source Rock Bulk Properties and Stable Isotopes web services on the Geoscience Australia Data Discovery Portal at https://portal.ga.gov.au which will be periodically updated. {"type": "Polygon", "coordinates": [[[112.0, -44.0], [154.0, -44.0], [154.0, -9.0], [112.0, -9.0], [112.0, -44.0]]]} 112.0 154.0 -44.0 -9.0 Data Management And Data Science EFTF – Exploring for the Future Energy Systems Exploration geochemistry Information Systems Isotope geochemistry ORGCHEM schema Onshore Energy Systems Organic geochemistry Published_External Sedimentary rocks Source rocks aromatic hydrocarbon bulk composition carbon isotopes elemental composition extractable organic matter (EOM) hydrogen isotopes laboratory analyses nitrogen isotopes saturated hydrocarbon saturated, aromatic, resin, asphaltene (SARA) fractions stable isotopes sulfur isotopes Link to Geoscience Australia Data Discovery Portal documentDigital Link to Geoscience Australia Data Discovery Portal HTML Link to Geoscience Australia Data Discovery Portal - Source Rock and Fluid Atlas documentDigital Link to Geoscience Australia Data Discovery Portal - Source Rock and Fluid Atlas HTML
