| 摘 要： | 资阳地区灯影组为一套形成于潮坪环境、以藻白云岩为主的地层，岩层中发育大量的葡萄花边构造。通过对葡萄花边、藻白云岩、充填白云石进行岩矿鉴定、电镜扫描、Ｘ射线衍射、碳氧同位素、微量元素等的分析，并结合本区成岩演化史，认为葡萄花边有两种成因：（１）准同生混合水成因；（２）表生混合水成因。葡萄花边的存在，能够指示溶蚀作用的存在，因而对研究古岩溶储层具有重要意义。

| Abstract: | Dengying Formation of Sinian is a set of algal dolomitite forming at tidal flat, and in which the botryoidal lace can be often seen. Throng studying in very detailed by a series analysis such as: thin section, SMZ, X ray diffraction, isotopes, traces elements of botryoidal lace, protolith and filling dolomites, it can be disclosed that botryoidal lace has two kinds of origins: a. penecontemporaneous mixing water origin; b. epigenetic mixing water origin. Because the botryoidal lace can indicate dissolution(especially palo karst), it has the important significance for the study of palo karst reservoirs. |
