“…Petroleum and low-temperature hydrothermal Au deposits may form together and exhibit similar evolutionary trends in their formation, migration, and enrichment. Under certain circumstances, oil reservoirs and low-temperature hydrothermal Au deposits, such as Carlin-type deposits, exhibit a close coupling relationship on macro-to micro-scales [1][2][3][4][5][6][7] that may manifest in three ways, as follows. (i) Oil and gas reservoirs and Au deposits may have similar spatial distributions.…”

“…Currently, many geologists focus on the role of hydrocarbon fluid in the metallogenic process, the ability to mobilize and transport metal elements, and the metallogenic mechanism of hydrocarbon fluid during basin evolution [3,4,27]. Noble metals such as gold are thought to play a catalytic role in the process of hydrocarbon generation to improve the efficiency of hydrocarbon generation [5]. Petroleum is thought to provide reduced sulfur directly or indirectly for sulfide precipitation during mineralization [1].…”

Gold and petroleum are also strategic resources of great importance to national security. With the increasing demand for energy, multi-energy cooperative exploration has become an inevitable trend of resource development and utilization. Petroleum and hydrothermal gold deposits may form together, with similar evolutionary trends in their formation, migration, and enrichment. Petroleum reservoirs and gold deposits are closely coupled under certain geological conditions. The solubility of gold in crude oil and its forms of occurrence are important in determining the mechanisms of interaction between gold and petroleum and in facilitating the recovery of gold from gold-bearing petroleum. In this study, the occurrence of gold in crude oil from the Linnan Depression in the Bohai Bay Basin, China, was studied using inductively coupled plasma–mass spectrometry and X-ray photoelectron spectroscopy. Concentrations of gold in crude oil from the Linpan and Shanghe oilfields averaged 44.5 ppb, which is well above the minimum concentration required for hydrothermal gold mineralization. Gold has an affinity with carbon, oxygen, and sulfur, and its concentration in crude oil is positively correlated with total acid and sulfur contents. We speculate that gold may exist in crude oil as complexes with organic acids or thiols, with crude oil thus being a transport medium for gold.
