【摘要】 根据大量的扫描电镜照片和辅助的X射线能谱分析资料,对残积红粘土微观结构进行了分类研究,指出前人研究不足之处是没有充分考虑土的形成条件、形成环境、土的成因以及组成矿物成分和形态。经研究认为,残积红粘土具有叠片状、絮凝状、粒斑状、斑状、斑块状、球粒状等结构,这些结构与组成红粘土的矿物形态及其成因密切相关。更多还原

【Abstract】 According to a large number of photograph of scanning electron microscope and Xray energy spectrum, microtexture of residual red clay and their classification are studied,and at the same time noted that some former researchers have not sufficiently consider the forming conditions, the environment, the genesis, the mineral composition and their shape in the studies on microtexture of red clay. Through preliminary research by SEM., there are following microtexture in the studied residual red clay: multiplefilm shape, floc shape, granularspotted shape, spotted shape, patch shape, pelletoidshape and so on. They are very closely related to the shape of minerals and the origin of residual red clay. 更多还原
