摘要
本文首次运用Ｘ射线能谱仪与扫描电镜耦合技术，对碳酸盐岩天然风化样品和溶蚀试验后样品进行了点扫描分析，定点地研究了微区空间化学成分配置关系对微观溶蚀形态的影响，在罕见晶形方解石矿物的确定、溶蚀过程中化学成分的演化与重新配置，鲕粒灰岩的差异性溶蚀，不溶物颗粒周围的环形溶孔成因等方面得到了一些新的认识。
This paper studies the micro-corrosive features of carbonate rock samplcs(includingnatural weathering samples and corrosive test samples)by point scanning analysis with SEMand energy dispersive X-ray spectrometer(EDX).The relationship between corrosive micro-morphological features and chemical compositions of rock can be shown by comparing EDXspectrums in different micro-areas. The author gets some new ideas in respect of carbonate mineral morphology,evolution of chemical compositions during corrosive test,differentialcorrosion of oolitic carbonate rock,and origin of circular pores surrounding an insoluble par-ticle.
