摘要
本文首次运用ｘ射线波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岩样进行了线扫描分析，定位地研究了化学成分和微观溶蚀形态的关系。尽管溶孔溶隙的发育和演化受岩石成分、矿物和岩石结构、渗流条件、岩石赋存环境等因素综合控制，但可溶质与非可溶质的配置关系仍然起着重要作用。
This paper studies the micro-corrosive features of carbonate rock samples(includingnatural weathering samples and corros ive test samples)by linear scanning a nalysis withSEM and fitting it wavelength dispersive X-ray spectrometer.Photomicrographs show thateven though corrosive micromorphology is controlled comprehensively by many factorssuch as chemical composition, microstructure of carbonate minerals and rocks,waterpercolation features, and rock occurrence environment as well,the inhomogeneity of chem-ical composition in micro- areas or distribution relationship between soluble and insolublecomponent plays a very important role. By use of the method,on the one hand, themicro-corrosive mprphology.can be shown;on the other hand,the chemical compositionof rocks and relative change in a given scanning line can be determined,in turn, the rela-tionship between them can be established.Therefore,it is a very versatile and powerful toolfor studying micro-karstific mechanism.
