| 摘 要： | 闽西南丁屋岭一带浅变质岩系中夹持着一套紫红色粗碎屑岩系 ,1970年《长汀幅》区域地质调查时将其划为震旦系南沱组下段 ,之后改称丁屋岭组下段 (习称“丁屋岭砾岩”) ,认为是澄江运动或晋宁运动的产物。长期以来因缺少化石 ,对其地层划分和时代归属一直存在争议。本次《瑞金市幅》区调工作首次在“丁屋岭砾岩”中获得孢子 ,为将“丁屋岭砾岩”置于上泥盆统提供了有力证据

| Abstract: | A set of purple-red coarse detrital rocks intercalated within a slightly metamorphized Sinian—Cambrian rock series was taken as the lower part of the Sinian Nantuo Formation in 1970, and subsequently remaned the lower member of Dingwuling Formation——the “Dingwuling Conglomerate” and considered to be Pre-Sinian or Sinian in age. Much dispute as regards its chronological correlation remains to be solved. Recently, some spores,?Retispora lepidophyta, Cymbosporites sp., Archaeozonotriletes sp., Stenozonotriletes sp.,etc. have been found from its top of the Conglomerate in a section around the Dingwuling area of southwestern Fujian, and the discovery of these spores indicates the Dingwuling Conglomerate should be Late Devonian in age. |
