The authors have summarized relevant data studied by overseas scientists and suggested the definition of chalky texture formation as "Chalky texture formation refers to that magnesium calcite and aragonite are transformed into the framework of micrite and microspar of low-magnesium calcite via neomorphism, and result in and maintain intercrystalline pore and throat networks in it; enhanced chalky texture formation refers to that the micrite and microspar are successively subjected to dissolution and leaching, so that the secondary network of solution voids is formed".

综合各国学者的有关研究资料，建议将白垩状结构化定义为：&碳酸盐沉积物和碳酸盐岩中的镁方解石和文石在不同成岩阶段通过新生变形而转变成低镁方解石微晶和微亮晶格架，并在其中产生和保存晶间孔喉网络的作用；强化白垩状结构化是指微晶和微亮晶格架受到进一步溶蚀和淋滤，从而形成次生溶蚀孔隙网络的作用&。
