| 摘 要： | 长坡油页岩矿区位于海南岛的北部,是北部湾盆地南部坳陷的一个次级单元。区内沉积盖层主要为新近系的陆相和海相地层。长坡组地层自上而下按岩性分为5段,油页岩主要赋存在第四段中,与褐煤互层产出。油页岩矿层产状平缓,构造简单,按产出位置分为上、中、下3层。通过对油页岩矿沉积特征及形成环境研究,表明油页岩形成于气候温暖湿润陆相湖泊沼泽相环境。

| Abstract: | Changpo oil shale exploration area,a sub-unit of south depression in Beibuwan Basin,locates in the north of Hainan Island.Sedimentary strata in this area mainly consist of Neogene continental strata and marine strata.The Changpo Formation is divided into five lithological segments.Oil shale imbedding with lignite was deposited in the fourth segment.The sedimentary characteristics indicate the oil shale deposited in lacustrine-swamp environment and turf-swamp environment.The oil shale beds are flat and the tectonic structure is simple.The oil shale is subdivided into three layers.Research on depositional characteristics and forming environment indicates that oil shale was formed in warm and wet continental lake-swamp environment. |
