The bayan bold gold deposit is situated in the obduction zone of platform margin to the north of inner mongolian suture zone 摘要白音宝力道金矿床位于内蒙古古缝合带北侧的陆缘逆冲带内。
In addition, by means of seismic profiles, the platform margin and the platform inner sag margin can be finally identified, integrated with distribution of organic reefs 分析中上奥陶统烃源岩沉积环境,重要的是寻找碳酸盐岩台地边缘、台地内凹陷边缘,从而能够确定台缘斜坡、台地内凹陷、陆棚等烃源岩沉积环境。
The carbonate source rocks of middle-upper ordovician in tarim basin are widely distributed in different sedimentary environments at the same period such as platform margin slope, platform inner sag, continental shelf, abyssal basin, etc 摘要塔里水盆地中上奥陶统碳酸盐岩烃源岩在同一时期不同的沉积环境(台缘斜坡、台地内凹陷、陆棚、深海盆地等)中均有发育。
According to the differences of sedimentary facies and environment, the source rock are divided into four types such as lime-mud reef in platform margin, platform inner sag, deep-water flat slope or continental shelf, abyssal basin, the lime-mud reef type is distributed in platform margin of upper ordovician, the remained three types are widely distributed in cambrian-ordovician system 根据沉积相带与沉积环境的不同,可将烃源岩划分为在不同沉积环境中的4种类型烃源岩;台地边缘灰泥丘型烃源岩、台地内凹陷型烃源岩、深水缓坡与陆棚型烃源岩、深海盆地型烃源岩。
