| 摘 要： | 滇西保山—施甸地区泥盆系沉积相类型包括碳酸盐台地相、陆棚相反盆地相。其中碳酸盐台地相可划分为台地边缘生物礁、台地边缘浅滩、台缘斜坡及开阔台地相和礁后泻湖-潮坪等亚相。根据其沉积特征及陆源碎屑岩化学成分的判别分析结果,泥盆纪时该区沉积盆地的大地构造性质属早期的被动大陆边缘或裂陷带边缘。

| Abstract: | The sedimentary facies type of Devonian in Baoshan-Shidian district consists of carbonate platform, shelf, slope and basin facies. The carbonate platform facies can be subdivided into platformmargin reef, platform-margin shoal, fore-platform slope, open platform and lagoon-back reef-tidal flat facies. According to the sedimentary feature and the discriminant scores of chemical composition of the sandstones, the property of the depositional basin during Devonian in Baoshan-Shidian district is of passive continental margin or aulacogen edge environment. |
