| 摘 要： | 分析了赣南三百山盆地地层层序和岩石地层划分的研究现状及存在分歧的原因,提出前人建立的地层层序与野外新发现的地质事实不相吻合,三百山盆地不存在所谓的双峰式火山岩组合和推覆构造。依据地层层序律,将三百山盆地自下而上可划分为砂岩层、长英质火山岩层、镁铁质火山岩层和砂砾岩层四套;通过地层对比,将第一套砂岩层划归上侏罗统武夷群双峰岭组、第二套长英质火山岩层划归上侏罗统武夷群鹅湖岭组、第三套铁镁质火山岩层和第四套砂砾岩层划归下白垩统罗塘群白埠组。

| Abstract: | The analyses for the research state and existent bifurcation according to strata sequence and lithostratigraphic division in Sanbaishan Basin show that the former strata sequence is conflicting with new phenomena detected in the field, there are not any double-peaking association of volcanic rocks and nappe structure in Sanbaishan area. The late Mesozoic strata in Sanbaishan Basin from bottom to top can be divided into four beds, i.e. sandstone, felsic volcanic rock, mafic volcanic rock and sand-conglomerate, on the basis of stratigraphic sequence. Through stratigraphic correlation first set of sandstone bed is incorporated into upper Jurassic Shuangfengling formation of Wuyi group, second set of felsic volcanic rock into upper Jurassic Ehuling formation of Wuyi group, third set of mafic volcanic rock and four set of sand-conglomerate into lower Cretaceous Baibu formation of Luotang group. |
