Scanning electron microscopy of calcium oxalate stones indicates a zonary structure of the Weddellite crystals of urine concrements which is due to concentration-dependent growth oscillations representing the precipitation of various calcium oxalate hydrates. In addition to the phenomenological demonstration of Weddellite crystal shapes, incubation experiments with different solutions give rise to the postulation of a dehydration process of primary Weddellite crystals via dissolution and recrystallization to Whewellite. The solvent attack starts at energetically preferred corners, edges and lattice disorders of the Weddellite crystals. The Weddellite-stabilizing role of urinary Mg ions is emphasized.
草酸钙结石的扫描电子显微镜检查表明，尿结石的水草酸钙晶体具有带状结构，这是由于浓度依赖性生长振荡导致的，代表了各种草酸钙水合物的沉淀。除了对水草酸钙晶体形状进行现象学展示外，用不同溶液进行的孵化实验还引发了一种假设，即初级水草酸钙晶体通过溶解和再结晶脱水形成方解石。溶剂侵蚀始于水草酸钙晶体能量上优先的角、边和晶格无序处。强调了尿液中镁离子对水草酸钙的稳定作用。
