琼州海峡西口表层沉积物地球化学特征及其对沉积环境的指示

Key Points

• The western entrance of Qiongzhou Strait shows significant variance in sediment geochemical characteristics, indicating diverse sources.
• Key elements like SiO2 and TiO2 suggest that sediment sources primarily originate from Hainan Island granites and basalt weathering products.
• Geochemical analysis and particle size assessment identify a strong oxidation environment reflected by materials such as MnO and P2O5 levels.
• Findings underscore the complex dynamics of sedimentation processes and their implications for understanding regional geological structures.
