Uzon volcano caldera (Kamchatka): A unique natural laboratory of the present-day naphthide genesis

Research at Uzon volcano caldera, Kamchatka, reveals it as a unique natural laboratory for studying present-day oil formation. Analysis of thermal spring oil shows using gas chromatography–mass spectrometry demonstrates that these compounds share genetic identity with organic matter from Pliocene–Quaternary deposits, confirming their biogenic origin. The study debunks theories suggesting hydrothermal abiogenic synthesis, providing critical insights into naphthide genesis processes in volcanic environments.
