Origin, Migration, and Accumulation of Crude Oils in the Chaoyang Step-Fault Zone, Fushan Depression, Beibuwan Basin: Insight from Geochemical Evidence and Basin Modeling
The Fushan Depression is a hydrocarbon-rich depression in the Beibuwan Basin, South China Sea.In this study, 14 source rocks and 19 crude oils from the Chaoyang Step-Fault Zone and Southern Slope Zone were geochemically analyzed to determine their origins.The hydrocarbon generation, migration, and accumulation processes were also determined using t
