| 摘要: |
| 利用砂岩碎屑颗粒类型、砂岩组分阴极发光、重矿物组合、砂体百分含量变化,以及岩相古地理格局等物源分析的方法,对珠江口盆地惠州凹陷古近纪沉积期进行了物源分析。结果表明,恩平组发育了一套沼泽、三角洲-浅湖沉积体系,物源来自于盆地北部和中部隆起带;珠海组发育了一套三角洲-浅海沉积体系,物源来源于北部隆起带。 |

| Abstract: |
| The provenance analysis of the Palaeogene has been studied in the Huizhou depression, Zhujiangkou Basin, Guangdong. clastic type, cathodoluminescence, heavy mineral assemblage, sandstone percentage and palaeogeographic framework from Enping and zhuhai Formation suggest that The Enping Formation consists of the swamp, delta -shallow lak e depositional systems and the source of detritus was mainly derived from the northern and southern uplifted zones in the basin, and the Zhuhai Formation was made up of the delta -shallow marine depositional systems and the principal source of detritus was derived from the northern uplifted zones in the basin. |
