摘要
本文主要研究朋村—盘龙中下泥盆统碳酸盐岩的物质成分特征及成岩作用。岩石以灰岩与白云岩为主,很少出现过渡类型的岩石。成岩过程中的压实作用、压溶作用以及新生变形作用都有明显的表现。应用阴极发光分析方法与岩组分析方法确定了成岩过程中形成的胶结物,区分了亮晶与假亮晶,为压溶作用提供了可靠的证据。
The diagenesis and the compositional characteristics of carbonate rocks of middle-lower Devonian in Pengcun-Panlong are studied in the article. Limestons and dolostones are the main types of carbonate rocks. Transtional rock types seldom appear. The compaction, pressure solution and neomorphism in diagenesis are distinctive. We determine cements formed in diagenesis, distinguish spar from pseudospar and provide dependable evidence for compaction by means of fabric analysis and cathodo-luminescence microscopy.
