| 中文摘要: |
| 本文介绍了氧同位素找矿方法的基本原理,采样要求和一些应用实例.对于热液矿床来说,成矿热液中H2O和CO2是最活泼的组分.它们对矿化围岩的影响十分显著,范围也很大,从而很容易改变其同位素比值,形成清晰均匀的同位素晕.通常,在热(矿)源体的周围,δ18(和δ13C)值常形成一个明显的低"谷".利用这种"谷"的标志来指导找矿,特别是找寻盲矿(岩)体具有重大意义. |
| 英文摘要: |
| The basic principies of mineral exploration using oxygen isotopes are introduced in this paper,as well as the collection of the samples and some applying examples.According to hydrothermal deposits,H2O and CO2 in ore-forming solution are the most active elements which have a strong and wide affections upon the host rocks.Therefore the isotope compositions are changed very easily and formed a clear and uniform isotopic abnormal halo.In general,the value of δ18O (or δ13C) formng a clear low "V" shape is very useful in mineral exploration,especially in finding buried ore and rockbodies. |
