The belief that hydrocarbon-rich areas correlate with deep-seated structural features of the crust is supported by several factors. According to the search results, hydrocarbons are often found in geographic patterns of long lines or arcs, which are related to deep-seated large-scale tectonic structures source. These structures can create traps at various levels where hydrocarbons accumulate due to structural deformation source. Additionally, deep fault systems that penetrate the lower crust may facilitate the transfer of hydrocarbon-rich fluids from greater depths source. Furthermore, the abiogenic hypothesis suggests that hydrocarbons form deep within the Earth's crust under high pressure and temperature conditions, and then migrate to the surface source. These factors collectively contribute to the correlation between hydrocarbon-rich areas and deep-seated structural features of the crust.
