摘要
贵阳中三叠世垄头组发育于扬子台地西南缘浅水碳酸盐岩台地向黔桂湘碎屑岩深水盆地的过渡带,主要由生物碎屑灰岩,藻纹层灰岩,含砾屑颗粒灰岩以及角砾灰岩组成。并通过渗流豆粒灰岩的岩石学特征、垄头组渗流豆粒的碳氧同位素特征进行了详细的分析。
Head group of the Triassic ridge in guiyang shallow-water carbonate platform of sw development in Yangtze platform to qian Gui Xiang clastic rock of deep water basin transition zone, is mainly composed of bioclastic limestone, algal laminated limestone, conglomeratic crumbs limestone particles and the composition of brecciated limestone. And through petrology characteristics of seepage bean grain limestone, ridge head group of carbon and oxygen isotope characteristics of seepage pea has carried on the detailed analysis.
