Stalagmites have the advantages of wide distribution, long-time span, well-preserved after formation, and various proxy indicators compared with other paleoclimate proxies. The widely applied proxy in stalagmites is oxygen isotope (δ18O), though there are many debates about its significance. In order to deepen the understanding of this important paleoclimate indicator, this paper lists the geochemical significance of oxygen isotope and briefly introduces its application in cave sediments within the region of monsoonal China. %K 氧同位素, %K 地球化学, %K 洞穴沉积物, %K 古气候
