中文摘要：
陡山沱早期，沉积环境自北西向南东可大致分为碳酸盐台地潮上坪-台缘浅滩相和浅海陆棚盆地相；陡山沱晚期，自北西向南东可大致分为开阔台地相区和深水陆棚-次深海相区。庙河型生物群的产出位于晚期开阔台地向深水陆棚-次深海过渡相区中的黑色页岩、硅质页岩中，其沉积环境为最大浪基面以下的宁静、贫氧环境，其沉积方式为悬浮沉积。
英文摘要：
Sedimentary environments in northeastern Guizhou and its adjacent areas may be divided into the intraplatform supertidal flat -periplatforrn shoal and shallow-sea shelf basin facies during the early Doushantuoan, and deep-water shelf-bathyal facies also from northwest to southeast during the late Doushantuoan. The Miaohetype biotas occur in the black shale and siliceous shale in the transitional areas from the late open platform facies to deep-water shelf-bathyal facies. The preceding sedimentary environments are interpreted as the quiet and dysaerobic environments below the maximum wave base, and suspension deposition acts as a main kind of depositional styles.
