中文摘要:

      本文利用扫描电镜,通过对碳酸盐岩试样的观察,系统研究了其矿物特征、微观喀斯特作用机理及喀斯特孔隙类型.研究表明,表面反应控制下的选择性溶蚀是微观喀斯特作用的最本质特征,碳酸盐矿物的菱形解理是选择性溶蚀的优势点,岩石结构控制了喀斯特孔隙的发育和演化.

英文摘要:

      SEM is a versatile and pewed tool for undetrstanding the textur and pore rpace properties of mineralsls and rocks as well as karst mechanism Based on the observations of rock samples by SEM the authors have studied Systematically the crystalline properties of carbonate minerals,micro-mechanism of karst pore type.
