云南老王寨金矿区煌斑岩与金矿化在时间上、空间上密切共生。主要元素分析表明，本区煌斑岩属钾质－富绅质钙碱性煌斑岩；与原始地幔和大洋中脊玄武岩相比，岩石相对富集稀土元素；模拟计算表明，岩石来源于稀土元素相对富集的交代富集地幔；地质发展史、不相容元素分配型式、Ｓｒ、Ｎｄ同位素组成及有关模拟计算表明，俯冲进入地幔楔的地壳物质脱水形成的流体是引起该区地幔交代作用的主要因素。
The lamprophyres and gold mineralization in the Laowangzhai gold deposit in Yunnan Province are symbiotic in time and space. The main elemental analysis shows that the lamprophyre in this area is a potassic-rich-rich calc-alkali lamprophyre; compared with the original mantle and mid-oceanic basalts, the rocks are relatively enriched in rare earth elements; and the simulation results show that the rocks are derived from rare earth The enrichment of the elements enriched the mantle; the history of geological evolution, the pattern of incompatible elemental distributions, Sr, Nd isotopic composition and related simulations show that the fluids formed by dehydration of crustal materials subducting into the mantle wedge are responsible for the metasomatism The main factor.
