介绍了氢氧同位素水／岩反应的基本原理及有关参数的确定，在此基础上给出了热液矿床的氢氧同位素水／岩反应演化曲线，确定了水／岩比值（W／R）.根据δ（18O）值空间变化，得出岩浆热液成因的矿床由矿体→蚀变岩→未蚀变岩，其δ（18O）值呈逐渐降低的趋势，即矿化中心正是δ（18O）的高值区，这对找矿具有重要的指导意义.
The basic principles of water / rock reaction of hydrogen and oxygen isotopes and the determination of relevant parameters are introduced. Based on this, the evolution curves of hydrogen and oxygen isotopes of water / rock in hydrothermal deposits are given, and the water / rock ratio (W / R) According to the spatial variation of δ (18O), the origin of magmatic hydrothermal deposits is from ores → alteration rocks → unchained rocks, and the δ (18O) values show a gradually decreasing trend, that is, the mineralization centers are δ (18O) high value area, which has important guiding significance for prospecting.
