| 摘 要： | 对泉州湾13个表层沉积物样品进行了矿物碎屑定量分析．通过矿物分析，发现泉州湾不同站位的轻、重矿物组分、含量和表征存在差异．根据矿物的分布和组合特征．将耒州湾划分为4个组合区，不同组合区所处沉积环境是不同的．分析表明，研完区表层沉积物的碎屑矿物具有明显的亲陆性，物质来源主要为河流输砂和沿湾海岸侵蚀来砂，且其分布受物源、水动力条件和矿物物理性质等因素所控制。 |
| 关 键 词： | 泉州湾海域 表层沉积物 矿物碎屑 分布特征 环境差异 组合特征 矿物分析 |

| Abstract: | The quantitative analysis of mineral detritus in 13 surface sediment samples from the Quanzhou Bay was made, and it is shown from the analysis results that the compositions, contents and characteristics of light and heavy minerals at different stations in the Quanzhou Bay are different from each other. Based on the mineral distributions and assemblage characteristics, the Quanzhou Bay can be divided into 4 assemblage provinces, and the sedimentary environments in different assemblage provinces are different. It is shown from the analysis results that the detrital minerals in surface sediment from the bay are obviously terrigenous, the main material sources are sediment discharged by rivers and eroded sediment from the Quanzhou Bay coast, and the distributions of the detrital minerals are mainly controlled by the material source, hydrodynamic condition and mineral physical properties. |
| Keywords: | Quanzhou Bay mineral detritus assemblage characteristics environmental difference |
