| 摘 要： | 茂名盆地是一个半地堑式盆地,金塘油页岩矿区位于茂名盆地中部。油页岩主要赋存于始新渐新统油柑窝组。钻井、孢粉等化石资料分析表明其形成于亚热带温带温暖潮湿气候下的半深湖深湖相沉积环境,受盆地北部边缘的高棚岭控盆断裂控制。受其影响油页岩从西南向东北方向厚度逐渐增大,后期受北西向断裂破坏,油页岩层产生较大落差。

| Abstract: | Jintang mining area of oil shale lies in the central Maoming Basin which is a half-graben basin.The oil shale mainly occurs in the Eocene-Oligocene Youganwo Formation.The data of drilling,spores-pollen and the fossils show that the Jintang oil shale formed in semi-deep to deep lacustrine facies under the warm and moist climatic conditions of subtropical-to temperate-zones.Dominated by Gaopengling fault,an ore controlling fault,in the northern margin of the basin,the thickness of the oil shale gradually increases from southwest to northeast.Therefore,the thickness of oil shale-bearing strata exist with a great difference afterwards owing to the effect of the northwest direction fault. |
