In 2014–2016 more than 600 specimens of semi-solid crude oil were recovered from 30 ocean beaches along the coastline of South Australia, as part of the recently completed Great Australian Bight Research Program. All are believed to be products of submarine oil seepage. Their source-specific biomarker signatures provide the basis for their assignment to sixteen oil families, some previously unrecognised. Two of these families (asphaltite and asphaltic tar) likely originated from Cretaceous marine source rocks in the offshore Bight Basin. The others comprise waxy oils of lacustrine, fluvio-deltaic and marine source affinity. Their biomarker characteristics do not match those of any Australian crude oil. However, they are strikingly similar to those of oils found in Cenozoic and Mesozoic basins throughout the Indonesian Archipelago and elsewhere in Southeast Asia.

搁浅在南澳大利亚海岸线上的原油的特征和来源。第二部分:潜在的母石油系统

2014-2016 年,作为最近完成的大澳大利亚湾研究计划的一部分,从南澳大利亚海岸线的 30 个海滩中回收了 600 多个半固体原油标本。所有这些都被认为是海底石油渗漏的产物。它们特定于来源的生物标志物特征为将它们分配到 16 个油族提供了基础,其中一些油族以前未被识别。其中两个家族(沥青岩和沥青焦油)可能起源于近海 Bight 盆地的白垩纪海相烃源岩。其他包括湖相、河流三角洲和海洋来源的蜡质油。它们的生物标志物特征与任何澳大利亚原油的特征都不匹配。然而,
